The effectiveness of SIT depends on the ability of the released sterile males to mate with and inseminate wild females. Irradiation is effective for sterilizing mass-reared insects, and the negative impacts of this procedure are not limited to reproductive cell damage. In this study, we evaluated the death-feigning that is considered as an antipredator behavior of male Cylas formicarius (Summers) (Coleoptera: Blentidae) irradiated with 200 Gy, which is the dose used in the SIT program in Okinawa Prefecture. Irradiated male insects were observed in the laboratory for 10 d after irradiation. On d 0, fewer irradiated males feigned death than nonirradiated males. The number of irradiated and nonirradiated males who feigned death and the duration of their death-feigning were about the same from 2 d after irradiation. On the basis of our results, we discuss the optimal release time of irradiated male C. formicarius.10aCylas formicarius1 aKuriwada, Takashi1 aKumano, Norikuni1 aShiromoto, Keiko1 aHaraguchi, Dai  uhttps://weevil.myspecies.info/effect-irradiation-death-feigning-behavior-male-sweetpotato-weevil-cylas-formicarius-coleoptera-blen01885nas a2200193   4500008004100000020001400041245014100055210006900196260000900265300001200274490000700286520115300293653002701446100002201473700002101495700002101516700001901537856013501556       2009                        eng d  a0015-404000aHigh population density and egg cannibalism reduces the efficiency of mass-rearing in Euscepes postfasciatus (Coleoptera: Curculionidae)0 aHigh population density and egg cannibalism reduces the efficien  cJune  a221-2280 v923 aThe West Indian sweetpotato weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) is a major pest of sweetpotato Ipomoea batatas (L.) Lam (Solanales: Convolvulaceae) in some countries. In order to improve mass-rearing for an eradication program employing the sterile insect technique (SIT), optimal population density of E. postfasciatus in an artificial diet was examined. Six population densities (1000, 4000, 7000, 10000, 13000, and 16000 individuals per container with 200 g of artificial diet) were compared for effect on the number of eggs collected and hatchability. The total number of eggs collected after 24 d increased with an increase in population density and reached a saturation level at 13,000 individuals, whereas hatchability was not affected by population density. The results indicated that optimal population density in mass rearing was 13,000 individuals on 200 g of artificial diet. Furthermore, we examined cannibalism by adult weevils in the presence of other diets . The result suggested that egg cannibalism may be a major reason for the low rate of egg collection in the mass rearing of E. postfasciatus.10aEuscepes postfasciatus1 aKuriwada, Takashi1 aKumano, Norikuni1 aShiromoto, Keiko1 aHaraguchi, Dai  uhttps://weevil.myspecies.info/high-population-density-and-egg-cannibalism-reduces-efficiency-mass-rearing-euscepes-postfasciatus-c02267nas a2200241   4500008004100000020001400041245011000055210006900165260000800234300001200242490000700254520143300261653002401694100002101718700002301739700002601762700002501788700002001813700002001833700002101853700002201874856012901896       2011                        eng d  a0015-404000aDIVERSITY OF SCOLYTINAE (COLEOPTERA: CURCULIONIDAE) ATTRACTED TO AVOCADO, LYCHEE, AND ESSENTIAL OIL LURES0 aDIVERSITY OF SCOLYTINAE COLEOPTERA CURCULIONIDAE ATTRACTED TO AV  cJun  a123-1300 v943 aThe redbay ambrosia beetle, Xyleborus glabratus Eichhoff (Coleoptera: Curculionidae: Scolytinae), is an exotic wood-boring insect that vectors laurel wilt, a lethal vascular disease of trees in the Lauraceae, including avocado (Persea americana) and native Persea species (redbay, swampbay). As part of research to identify host-based attractants for X. glabratus, we discovered that a diverse array of non-target ambrosia beetles was attracted to the same substrates as X. glabratus. During Sep-Dec 2009, several field tests were conducted in north Florida (in woodlands with advanced stages of laurel wilt) with traps baited with commercial lures of the essential oils, manuka and phoebe, and with freshly-cut wood bolts of avocado (a known host) and lychee (Litchi chinensis, a non-host high in the sesquiterpene [alpha]-copaene, a putative host attractant). In addition, manuka-baited traps were deployed in avocado groves in south Florida to monitor for potential spread of X. glabratus. The combined trapping results indicated that none of these substrates was specific in attraction of X. glabratus. Numerous non-target ambrosia beetles were captured, including 17 species representative of 4 tribes within the subfamily Scolytinae.

The antenna of parthenogenetic females and of both sexes of bisexual reproductive weevils consisted of the scape, pedicel, and 6 flagellar segments. Females, regardless of mode of reproduction, had longer antennal segments than males. The 3 adult forms/genders can be correctly classified into their respective groups with a set of discriminant mathematical functions based on 4 morphological measurements of length or maximum width of segments of the antennae. For both sexes, 6 morphological sensilla types were found on the antennae, including hydrofuge scales I (hsI), trichoid sensilla (ts), 2 types of squamiform sensilla (ssI, ssII), tuft hairs (th), and Bohm bristles (Bb). No remarkable sexual differences in the types or distribution of sensilla were found on the antennae among parthenogenetic and both sexes of bisexual reproductive weevils, except for hsI. Both the length and basal diameter of hsI of females were significantly greater than those of the males. The hsI of the parthenogenetic females were significantly longer than those of the bisexual females. The numbers of branches of hsI on the sixth flagellum of the parthenogenetic females were significantly more than on both sexes of bisexual adults. The numbers of branches of hsI of the females were significantly more than those of the males. From the information gained from this scanning electronic microscope study of antennae, we can separate rice water weevils by gender and reproductive mode.10aLissorhoptrus oryzophilus1 aKang, Gui-Juan1 aZhu, Zeng-Rong1 aCheng, Jia-An1 aWay, Michael, O.  uhttps://weevil.myspecies.info/antennal-sensilla-parthenogenetic-and-bisexual-lissorhoptrus-oryzophilus-coleoptera-curculionidae00822nas a2200181   4500008004100000245026000041210006900301300001200370490000700382100001500389700001500404700001400419700001500433700002500448700001800473700001400491856013500505       2002                        eng d00aExploration in Belize for parasitoids attacking eggs of citrus weevils and an evaluation of Pediobius irregularis and Horismanus bennetti (Hymenoptera : Eulophidae) as potential Biological Control agents of Diaprepes abbreviatus and Pachnaeus litus (Coleo0 aExploration in Belize for parasitoids attacking eggs of citrus w  a660-6630 v851 aHall, D.G.1 aEger, J.E.1 aPeña, J.1 aDuncan, R.1 aO'Brien, Charles, W.1 aEvans, G., G.1 aMcCoy, C.  uhttps://weevil.myspecies.info/exploration-belize-parasitoids-attacking-eggs-citrus-weevils-and-evaluation-pediobius-irregularis-an01444nas a2200169   4500008004100000020001400041245009000055210006900145260001300214300001200227490000700239520084900246653002401095100002101119700002501140856010901165       2011                        eng d  a0015-404000aNatural History of the Crambe feeder, Lixus circumcinctus (Coleoptera: Curculionidae)0 aNatural History of the Crambe feeder Lixus circumcinctus Coleopt  cDecember  a987-9920 v943 aField investigations showed that Lixus circumcinctus Boheman 1835 (Coleoptera: Curculionidae) is a major herbivore species living on Crambe orientalis in northeastern Anatolia and on Crambe tataria in central Anatolia.

A commercial preparation of this fungus was used to study its potential as a biocontrol agent of the citrus root weevil, Diaprepes abbreviatus. Laboratory reared adult weevils were placed in clean plastic bags with 0.05 g of powdered inoculum per bag, shaken for thirty seconds, and placed in holding cages. In order to determine the spore concentration, germination, and position of ingress, inoculated weevils were dipped in a collodion solution after 30 min, 6 h, 12 h, 18 h, and 30 h. Collodion peels from various areas of the exoskeleton were removed, stained with lactophenol cotton blue, and observed microscopically. At 12 h post-inoculation spores began to swell, and at 18 h close to 25% germinated on all body parts except on the elytra. After 30 h, between 45% and 75% of the spores germinated, depending on the body part. Most active spore germination occurred around the eyes (75%), followed by the ventral abdomen (65%), the dorsal pronotum (60%), scales (45%), and dorsal surface of the elytra (7%). Spores were washed from the surface of inoculated weevils with distilled water and plating onto potato dextrose agar. Spore density on the weevils' surface was determined to be 15,815 [plus or minus] 479 spores initially after inoculation, and was reduced to 5,782 [plus or minus] 136 spores after 3 h.10aDiaprepes abbreviatus1 aGillett-Kaufman, Jennifer, L.1 aKimbrough, James, W.  uhttps://weevil.myspecies.info/modified-method-visualize-infection-sites-spores-entomopathogen-beauveria-bassiana-deuteromycotina-h02492nas a2200325   4500008004100000020001400041245008500055210006900140260000900209300001200218490000700230520159600237653001401833653002101847653001001868653001301878653002001891100002501911700002501936700001401961700001401975700001401989700002202003700002302025700001702048700002002065700001902085700002102104856004102125       1996                        eng d  a0015-404000aChemical and behavioral ecology of palm weevils (Curculionidae: Rhynchophorinae)0 aChemical and behavioral ecology of palm weevils Curculionidae Rh  cJune  a153-1670 v793 aPalm weevils in the subfamily Rhynchophorinae (Curculionidae) (Rhynchophorus spp., Dynamis borassi, Metamasius hemipterus, Rhabdoscelus obscurus, and Paramasius distortus) use male-produced aggregation pheromones for intraspecific chemical communication.

(RPW). This pest of economic importance in regions of Asia, the Middle East, and the Mediterranean was not observed in the Americas until 2009. Due to its economic and environmental damage, there is an urgent need to manage or eradicate RPW in Curacao to reduce its impact on the island as well as avoid the possibility of transference to surrounding regions. Studies were conducted to explore methods available for monitoring adults with traps and acoustically assessing larval infestations in trees in the warm, dry but humid Curacao environment - considering also some special challenges of urban conditions, such as increased traffic noise or unwanted human curiosity that could negatively affect monitoring success. Bucket traps baited with 4- methyl-5-nonanol/ 4-methyl-5-nonanone pheromone lure, ethyl acetate and a molasses - ethylene glycol mixture captured RPW adults at consistent rates for ca. 7/d, but the rates of capture were reduced for the 9th to 14th d of a two-week sampling period. The weevils were observed to escape rapidly from dry traps but not from liquid-containing traps. A portable, user-friendly acoustic sensor system enabled identification of larvae in individual infested trees through the use of signal processing analyses that screened out bird and wind noise. This information gained about liquid baits and acoustic differences between background noise and RPW-produced sounds can assist future efforts to monitor, control, or eradicate RPW in Curacao as well as other urban landscapes.10aRhynchophorus ferrugineus1 aFiaboe, K., K.

In 5 commercial fields, insecticide-treated and untreated plots were established 4.5, 30 and 60 m from one edge of the field. Soil core samples were collected on 2 dates and inspected for L. oryzophilus immatures. Rice yields were determined by harvesting 15 m2 plots in 2009 or 1 m2 per plot in 2010. Analysis of variance (ANOVA) showed that in most locations, immature populations were higher in plots 4.5 or 30 m from the field's edge than in plots 60 m from the field's edge. Yields from treated and untreated plots did not differ significantly Linear regression of immature populations and rice grain yield per plot per location did not yield a significant, inverse density-yield relationship. Results indicate that border applications of insecticides for L. oryzophilus management are appropriate; however, growers are advised to inspect their fields to confirm border populations and effects on yield. Research needs regarding sampling and economic thresholds are discussed.10aLissorhoptrus oryzophilus1 aEspino, Luis  uhttps://weevil.myspecies.info/occurrence-and-abundance-lissorhoptrus-oryzophilus-coleoptera-curculionidae-relative-field-borders-c00588nas a2200157   4500008004100000020001400041245009700055210006900152260000900221300001200230490000700242100002100249700001900270700002100289856012000310       2009                        eng d  a0015-404000aSampling methods for Myllocerus undecimpustulatus undatus (Coleoptera: Curculionidae) adults0 aSampling methods for Myllocerus undecimpustulatus undatus Coleop  cJune  a388-3900 v921 aEpsky, Nancy, D.1 aWalker, Alison1 aKendra, Paul, E.  uhttps://weevil.myspecies.info/sampling-methods-myllocerus-undecimpustulatus-undatus-coleoptera-curculionidae-adults02423nas a2200205   4500008004500000020001400045245010500059210006900164260000900233300001200242490000700254520170900261653001401970100002101984700002602005700001902031700002102050700002202071856012402093       2008                        Engldsh    a0015-404000aLife history and damage of a new Baradinae Baridinae weevil (Coleoptera: Curculionidae) on amaryllis0 aLife history and damage of a new Baradinae Baridinae weevil Cole  cJune  a214-2190 v913 aA small Baradinae weevil that feeds on amaryllis plants has been known in Florida for over 15 years. It is yet to be named taxonomically and its life history has not been studied previously. Observations on weevil damage were made on containerized amaryllis (Hippeastrum hybrids) plants naturally infested in a greenhouse or used for colony rearing. Laboratory studies were conducted at ambient room temperature (75[degree]C) with excised leaves to obtain information on weevil life history. Adults lived about 3 months, and fed on basal versus apical leaf tissue. Females inserted eggs near the thickened leaf base, and eggs were 0.65 [plus or minus]0.02 mm long by 0.40 [plus or minus]0.01 mm wide. Females laid >400 eggs over their lifetime, with egg production increasing over the first 7 weeks and then tending to decline. Eclosion ranged from 51% for eggs removed from host tissue within 24 h to 84% for eggs removed from host tissue after 24 h of oviposition. In tests with excised leaf tissue, eggs hatched after 7.1 d and larval development was complete after 28.8 d, of which 9.9 d were spent as prepupae. In no-choice tests, survival was lower and pupal developmental time period was longer when larvae were reared on excised bulb versus excised leaf tissue. Although larval development was poorer on bulbs versus leaves in the laboratory studies, in intact plants larvae tunnel through leaf tissue towards the bulb where they feed and complete development. In severe infestations, larvae hollow out the inside of the bulb and may cause plant death. Adult damage is primarily to the foliage through feeding and oviposition. This is the first report to quantify the life history of this weevil.10aBaridinae1 aEpsky, Nancy, D.1 aWeissling, Thomas, J.1 aWalker, Alison1 aMeerow, Alan, W.1 aHeath, Robert, R.  uhttps://weevil.myspecies.info/life-history-and-damage-new-baradinae-baridinae-weevil-coleoptera-curculionidae-amaryllis00754nas a2200193   4500008004100000020001400041245013900055210006900194260000800263300001200271490000700283100001500290700003100305700002200336700002100358700002000379700002600399856013500425       2010                        eng d  a0015-404000aNEW RECORD OF RED PALM WEEVIL, RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: CURCULIONIDAE) ON ARECANUT (ARECA CATECHU) FROM MEGHALAYA, INDIA0 aNEW RECORD OF RED PALM WEEVIL RHYNCHOPHORUS FERRUGINEUS COLEOPTE  cSep  a446-4480 v931 aDutta, Ram1 aThakur, Narain, Singh Azad1 aBag, Tusar, Kanti1 aAnita, Ngashepam1 aChandra, Satish1 aNgachan, Shishomvanao  uhttps://weevil.myspecies.info/new-record-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-curculionidae-arecanut-areca-catechu02473nas a2200205   4500008004100000020001400041245012100055210006900176260000800245300000800253490000700261520173000268653001901998100002702017700002002044700002502064700002302089700002002112856013502132       2011                        eng d  a0015-404000aACQUIRED NATURAL ENEMIES OF THE WEED BIOLOGICAL CONTROL AGENT OXYOPS VITIOSA (COLEPOTERA COLEOPTERA : CURCULIONIDAE)0 aACQUIRED NATURAL ENEMIES OF THE WEED BIOLOGICAL CONTROL AGENT OX  cMar  a1-80 v943 aThe Australian curculionid Oxyops vitiosa Pascoe was introduced into Florida in 1997 as a biological control agent of the invasive tree Melaleuca quinquenervia (Cav.) S. T. Blake. Populations of the weevil increased rapidly and became widely distributed throughout much of the invasive tree's adventive distribution. In this study we ask if O. vitiosa has acquired natural enemies in Florida, how these enemies circumvent the protective terpenoid laden exudates on larvae, and what influence 1 of the most common natural enemies has on O. vitiosa population densities? Surveys of O. vitiosa populations and rearing of field-collected individuals resulted in no instances of parasitoids or pathogens exploiting weevil eggs or larvae. In contrast, 44 species of predatory arthropods were commonly associated (>5 individuals when pooled across all sites and sample dates) with O. vitiosa. Eleven predatory species were observed feeding on O. vitiosa during timed surveys, including 6 pentatomid species, 2 formicids and 3 arachnids. Species with mandibulate or chelicerate mouthparts fed on adult stages whereas pentatomids, with haustellate beaks, pierced larval exoskeletons thereby bypassing the protective larval coating. Observations of predation were rare, with only 8% of timed surveys resulting in 1 or more instances of attack. Feeding by the pentatomid Podisus mucronatus Uhler accounted for 76% of all recorded predation events. Podisus mucronatus numerically responded to fourth instars but no response was observed for other life stages. Damage to M. quinquenervia plants from feeding by O. vitiosa, however, was not influenced by P. mucronatus densities, indicating that predation does not alter plant suppression.10aOxyops vitiosa1 aChristensen, Robin, M.1 aPratt, Paul, D.1 aCostello, Sheryl, L.1 aRayamajhi, Min, B.1 aCenter, Ted, D.  uhttps://weevil.myspecies.info/acquired-natural-enemies-weed-biological-control-agent-oxyops-vitiosa-colepotera-coleoptera-curculio00660nas a2200169   4500008004100000020001400041245012700055210006900182260001300251300001400264490000700278100001600285700002000301700001800321700001600339856013500355       2011                        eng d  a0015-404000aFirst Report of Damage by the Sugarcane Root Weevil Diaprepes abbreviatus (Coleoptera: Curculionidae) to Florida Sugarcane0 aFirst Report of Damage by the Sugarcane Root Weevil Diaprepes ab  cDecember  a1063-10650 v941 aCherry, Ron1 aHall, David, G.1 aWilson, Alvin1 aBaucum, Les  uhttps://weevil.myspecies.info/first-report-damage-sugarcane-root-weevil-diaprepes-abbreviatus-coleoptera-curculionidae-florida-sug02699nas a2200169   4500008004100000020001400041245012500055210006900180260000800249300001200257490000700269520206600276653001502342100002002357700001702377856013502394       2010                        eng d  a0015-404000aEFFECTS OF HOST QUALITY ON FLIGHT MUSCLE DEVELOPMENT IN NEOCHETINA EICHHORNIAE AND N.

This reportedly alternates with oogenesis and is reversible. We examined host quality as a possible explanation for the transitions between these 2 states by allowing populations of the 2 species to develop on plants differing in nutritive quality and then examining the status of their ovaries and flight muscle development. The leaf nitrogen content of the plants increased directly with fertilizer treatment levels but herbivory by the weevils changed the pattern of variation. Neochetina eichhorniae suppressed overall nutritive quality while still enabling tissue nitrogen levels to increase with fertilizer treatments. Neochetina bruchi, however, negated these effects and tissue nitrogen levels failed to correlate with fertilizer treatments. As a result, herbivore intensity (the number of weevils per plant) and the proportion of the populations that responded in one way or the other (either oogenesis or flight muscle development) differed between the 2 species. Very few N eichhorniae responded in the lowest fertilizer treatment and none produced flight muscles. This increased in the intermediate treatments to about an 80% response with most individuals reproductive. At higher levels, the overall response declined somewhat with an increasing proportion becoming dispersive. Very few N bruchi developed flight muscles except in the highest fertilizer treatment. The frequency of reproductive N bruchi varied little across fertilizer treatments, tracking host quality instead. We conclude that transitions from reproduction to dispersal in these 2 species are not in response to low nutritive quality of the plant tissue and require adequate nutrition to occur. Host quality, however, is affected by a multitude of factors, including the intensity of herbivory, which complicates interpretation of nuanced responses.10aNeochetina1 aCenter, Ted, D.1 aDray, F., A.  uhttps://weevil.myspecies.info/effects-host-quality-flight-muscle-development-neochetina-eichhorniae-and-n-bruchi-coleoptera-curcul00666nas a2200157   4500008004100000020001400041245016900055210006900224260000800293300001200301490000700313520001600320100002000336700001700356856013500373       2010                        eng d  a0015-404000aA SIMPLE, EFFICIENT METHOD FOR EXTRACTING NEOCHETINA EICHHORNIAE AND N.

The weevils reared on 'Sukkary' showed significantly better growth expressed in most parameters such as length, width and weight at larval, pupal and adult stages. Significantly greater numbers of eggs were laid on cv. 'Sukkary' as compared to the other 3 cultivars. This might be because of higher sugar content of cv. 'Sukkary'. Adult lifespan was significantly longer on cv. 'Khasab'. Though more cocoons were harvested from 'Khalas', frequency of adult emergence was better on 'Sukkary'.

To facilitate behavioral and biological studies on this important pest, a study to optimize rearing procedures was conducted at King Saud University, Riyadh, Kingdom of Saudi Arabia. RPW pairs were introduced into date palm bolts and subsequent RPW populations were harvested at the pupal stage. The populations of RPW resulting from different numbers of introduced RPW pairs and the use of mated vs. virgin RPW pairs were compared for different date palm cultivars and sizes of the bolts. Results indicated that RPW can successfully be reared on date palm bolts. Subsequent population was increased with increases in numbers of introduced RPW pairs. Date palm cultivars significantly influenced the subsequent RPW population. Thickness of the date palm bolt wase positively correlated with the subsequent RPW population. Introducing mated vs. virgin RPW pairs did not show any significant effect on subsequent RPW population.10aRhynchophorus ferrugineus1 aAldawood, A., S.1 aRasool, K., G.  uhttps://weevil.myspecies.info/rearing-optimization-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-curculionidae-date-palm-ph01858nas a2200181   4500008004100000020001400041245013200055210006900187260001300256300001200269490000700281520114400288100002701432700002401459700003101483700002701514856013501541       2011                        eng d  a0015-404000aDistribution and Abundance of Phoretic Mites (Astigmata, Mesostigmata) on Rhynchophorus ferrugineus (Coleoptera: Curculionidae)0 aDistribution and Abundance of Phoretic Mites Astigmata Mesostigm  cDecember  a748-7550 v943 aThe red palm weevil, Rhynchophorus ferrugineus Olivier, is the most important insect pest on date palms. Weevils were collected from randomly selected infested date palms in Al Ain, United Arab Emirates (UAE). Mites from three families were recorded. Uroobovella sp. (Acari: Urodinychidae) were the most common phoretic mites. Curculanoetus sp. (Acari: Histiostomatidae) were second in abundance. Uropoda orbicularis (Acari: Uropodidae) was recorded on one beetle. The abundance of phoretic mites varied among body parts of R. ferrugineus, and the maximum numbers occurred in the subelytral space. The mean intensity, mean abundance, and prevalence of Uroobovella and Curculanoetus mites did not differ between male and female weevils. Uroobovella had significantly greater mean intensity, abundance and prevalence compared to Curculanoetus . Most Uroobovella and Curculanoetus aggregated under the sublytral space, which presumably offers protection from the hot and dry environment. This study is the first to document the presence of phoretic mites on R. ferrugineus in UAE and will help to direct future research on their interactions.1 aAl-Deeb, Mohammad, Ali1 aBin Muzaffar, Sabir1 aAbuagla, Abdullah, Mohamed1 aSharif, Eyas, Mohammad  uhttps://weevil.myspecies.info/distribution-and-abundance-phoretic-mites-astigmata-mesostigmata-rhynchophorus-ferrugineus-coleopter02108nas a2200181   4500008004100000020001400041245011400055210006900169260001400238300001200252490000700264520144400271653003001715100001601745700001901761700001701780856012901797       2009                        eng d  a0015-404000aLife history of the red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Dryophtoridae), in southern Japan0 aLife history of the red palm weevil Rhynchophorus ferrugineus Co  cSeptember  a421-4250 v923 aWe surveyed the life history of the red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae), in southern Japan, including seasonal changes in the flight activity of adults and composition of R. ferrugineus in different developmental stages in a total of 17 infested Phoenix canariensis trees which were cut down in 2003-2005. The flight of adults began in Mar, showed some peaks in summer and autumn, and ceased in mid-Dec. Various stages of individuals inhabited infested R canariensis trees throughout the year. The composition of individuals at different stages in late fall was dependent on the resource (white intact tissue) availability in R canariensis trees. In R canariensis trees where considerable resource remained, all stages of larvae, pupae, and adults were found, whereas in palm trees with no resource, few young- and medium-stage larvae were observed. The temperature in the infested part of a palm trunk was 30[degree]C or higher even in winter. From these results, we view the life history of R. ferrugineus in southern Japan as follows: Adults emerge from host trees in spring and continue to attack host trees until late fall. Rhynchophorus ferrugineus grows even in winter if intact tissue remains at the peripheral part of trunks, and there may be 3 or 4 generations per year. A cold winter probably does not have any negative effects on successful colonization of R. ferrugineus in Japan.10aRhynchophorus ferrugineus1 aAbe, Fukiko1 aHata, Kunihiko1 aSone, Koichi  uhttps://weevil.myspecies.info/life-history-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-dryophtoridae-southern-japan02348nas a2200181   4500008004100000020001400041245015300055210006900208260000800277300001200285490000700297520163600304653002601940100002201966700002301988700002002011856013502031       2011                        eng d  a0015-404000aLEAF GAS EXCHANGE AND DAMAGE OF MAHOGANY AND POND APPLE TREES FROM ADULT DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) FEEDING AND SOIL FLOODING0 aLEAF GAS EXCHANGE AND DAMAGE OF MAHOGANY AND POND APPLE TREES FR  cSep  a655-6680 v943 aThe effects of feeding on leaves by adult Diaprepes root weevil, Diaprepes abbreviatus L. (Coleoptera: Curculionidae), and flooding on leaf gas exchange (net CO2 assimilation (A), transpiration (E), and stomatal conductance (g,)), plant growth (root, stem, leaf, and total plant dry weights, stem diameter, and plant height) and adult host plant preference (feeding damage and oviposition) were determined on mahogany, Swietenia mahagoni Jacq., and pond apple, Annona glabra L., trees in outdoor screen cages. Flooding reduced leaf gas exchange, plant growth, and D. abbreviatus feeding damage of mahogany trees. Leaf gas exchange of infested and non-infested trees of both mahogany and pond apple were similar except for one measurement date for mahogany. Leaf dry weights were greater for non-infested than infested mahogany trees. There was no effect of infestation on dry weights of pond apple trees. Based on feeding injury to leaves, adults preferred non-flooded to flooded mahogany trees. The lack of response in leaf damage or oviposition to flooding for pond apple was attributable to the avoidance of leaves by adult D. abbreviatus of this plant species despite it being a host for root weevil larvae. The results indicate that while flooding of the root zone adversely affects growth and physiology of mahogany trees, it does not predispose trees to greater damage from adult D. abbreviatus. In fact, adult insect damage was greater for non-flooded than flooded trees. Pond apple was not greatly affected by root zone flooding and was not a preferred host of adult D. abbreviatus under flooded or non-flooded conditions.10aDiaprepes abbreviatus1 aMartin, Cliff, G.1 aMannion, Catharine1 aSchaffer, Bruce  uhttps://weevil.myspecies.info/leaf-gas-exchange-and-damage-mahogany-and-pond-apple-trees-adult-diaprepes-abbreviatus-coleoptera-cu02330nas a2200181   4500008004100000020001400041245016600055210006900221260000800290300001200298490000700310520160600317653002601923100002201949700002301971700002001994856013402014       2011                        eng d  a0015-404000aLEAF GAS EXCHANGE AND GROWTH RESPONSES OF GREEN BUTTONWOOD AND SWINGLE CITRUMELO TO DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) LARVAL FEEDING AND FLOODING0 aLEAF GAS EXCHANGE AND GROWTH RESPONSES OF GREEN BUTTONWOOD AND S  cJun  a279-2890 v943 aEffects of flooding and herbivory by Diaprepes abbreviatus L.

Raf. x Citrus paradisi Macf.) trees were tested. Growth and survival of the larvae were also examined. For each plant species, there were 2 larval infestation treatments (infested and non-infested) and 2 flooding treatments (flooded and non-flooded). Beginning 6 d after larval infestation, plants were flooded in three 1-wk cycles each with 2 d of flooding followed by 5 d of non-flooding. For green buttonwood, E was higher for non-flooded than flooded plants on the third of 5 measurement dates and A and gs were higher for non-flooded than flooded plants on the fifth (final) measurement date. For Swingle citrumelo, E and gs were higher for non-infested than infested plants on the fifth (final) measurement date. Root dry weight of Swingle citrumelo was higher for flooded, infested than for non-flooded, infested plants and for non-flooded, non-infested than for non-flooded, infested plants. Larval survival rate, head capsule width, and root damage rating of Swingle citrumelo were lower for flooded than for non-flooded plants, whereas flooding did not affect larval survival or growth on green buttonwood. Thus, short-term cyclical flooding of three 2-d cycles may control D. abbreviatus larvae on Swingle citrumelo but did not control larval populations or reduce damage on green buttonwood.10aDiaprepes abbreviatus1 aMartin, Cliff, G.1 aMannion, Catharine1 aSchaffer, Bruce  uhttps://weevil.myspecies.info/leaf-gas-exchange-and-growth-responses-green-buttonwood-and-swingle-citrumelo-diaprepes-abbreviatus01845nas a2200181   4500008004100000020001400041245013900055210006900194260000800263300001200271490000700283520114300290653002601433100002201459700002701481700002001508856013501528       2010                        eng d  a0015-404000aSURVIVAL OF DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) LARVAE ON GREEN BUTTONWOOD TREES IN FLOODED MARL SOIL AND POTTING MEDIUM0 aSURVIVAL OF DIAPREPES ABBREVIATUS COLEOPTERA CURCULIONIDAE LARVA  cJun  a153-1600 v933 aSurvival of Diaprepes root weevil Diaprepes abbreviates (L.)

Root-zone flooding may be a viable control option for flood-tolerant ornamental plants including buttonwood. Significantly more larvae survived after 38 d in non-flooded than in flooded marl soil. Similarly, more larvae survived in non-flooded than in flooded potting medium; no larvae were recovered from flooded potting medium. Larval survival rates were significantly higher in flooded marl soil than in flooded potting medium, but there was no difference in survival between non-flooded marl soil and non-flooded potting medium. Larvae recovered from flooded marl soil had significantly smaller head capsule widths and probably were at least 1 instar younger than larvae recovered from non-flooded marl soil or non-flooded potting medium.

Only redbay and 'Simmonds' avocado plants were killed, suggesting that avocado susceptibility to laurel wilt may vary among plants or cultivars of different genetic background.10aXyleborus glabratus1 aMayfield, A., E.1 aPena, J., E.1 aCrane, J., H.1 aSmith, J., A.1 aBranch, C., L.1 aOttoson, E., D.1 aHughes, M.  uhttps://weevil.myspecies.info/ability-redbay-ambrosia-beetle-coleoptera-curculionidae-scolytinae-bore-young-avocado-lauraceae-plan00549nas a2200133   4500008004500000020001400045245010200059210006900161300001200230490000700242653002500249100002500274856011600299       1982                        Engldsh    a0015-404000aHilipinus nearcticus, new species in a genus new to the United States (Curculionidae: Coleoptera)0 aHilipinus nearcticus new species in a genus new to the United St  a211-2150 v6510aHilipinus nearcticus1 aO'Brien, Charles, W.  uhttps://weevil.myspecies.info/hilipinus-nearcticus-new-species-genus-new-united-states-curculionidae-coleoptera00415nas a2200121   4500008004100000245006100041210006000102300001200162490000700174100001600181700001800197856007800215       1995                        eng d00aArthropods associated with Annona spp. in the neotropics0 aArthropods associated with Annona spp in the neotropics  a329-3490 v781 aPeña, J.E.1 aBennett, F.D.  uhttps://weevil.myspecies.info/arthropods-associated-annona-spp-neotropics00548nas a2200109   4500008004100000245015300041210006900194300001200263490000700275100002100282856013500303       1991                        eng d00aA New Species of Plocetes from the Florida Keys with Notes on Other Species Occurring in the United States (Curculionidae; Curculioninae; Tychiini).0 aNew Species of Plocetes from the Florida Keys with Notes on Othe  a105-1100 v741 aAnderson, R., S.  uhttps://weevil.myspecies.info/new-species-plocetes-florida-keys-notes-other-species-occurring-united-states-curculionidae-curculio00646nas a2200133   4500008004100000245019200041210006900233300001200302490000700314100001400321700001700335700002500352856013500377       2002                        eng d00aOld traps for new weevils: new records for curculionids (Coleoptera: Curculionidae), brentids (Coleoptera: Brentidae) and anthribids (Coleoptera: Anthribidae) from Jefferson Co., Florida.0 aOld traps for new weevils new records for curculionids Coleopter  a632-6440 v851 aBloem, S.1 aMizell, R.F.1 aO'Brien, Charles, W.  uhttps://weevil.myspecies.info/old-traps-new-weevils-new-records-curculionids-coleoptera-curculionidae-brentids-coleoptera-brentida00512nas a2200109   4500008004100000245012600041210006900167300001200236490000700248100001900255856012800274       1993                        eng d00aA new species of Pityophthorus Eichhoff (Coleoptera: Scolytidae) from southern Florida with a key to the Florida species.0 anew species of Pityophthorus Eichhoff Coleoptera Scolytidae from  a608-6160 v761 aAtkinson, T.H.  uhttps://weevil.myspecies.info/new-species-pityophthorus-eichhoff-coleoptera-scolytidae-southern-florida-key-florida-species00549nas a2200121   4500008004100000245012900041210006900170300001200239490000700251100001900258700001500277856013500292       1994                        eng d00aAnnotated checklist of the bark and ambrosia beetles (Coleoptera: Paltypodidae and Scolytidae) of tropical southern Florida.0 aAnnotated checklist of the bark and ambrosia beetles Coleoptera   a313-3290 v771 aAtkinson, T.H.1 aPeck, S.B.  uhttps://weevil.myspecies.info/annotated-checklist-bark-and-ambrosia-beetles-coleoptera-paltypodidae-and-scolytidae-tropical-southe02496nas a2200325   4500008004500000020001400045245008500059210006900144260000900213300001200222490000700234520159600241653001401837653002101851653001001872653001301882653002001895100002501915700002501940700001401965700001401979700001401993700002202007700002302029700001702052700002002069700001902089700002102108856004102129       1996                        Engldsh    a0015-404000aChemical and behavioral ecology of palm weevils (Curculionidae: Rhynchophorinae)0 aChemical and behavioral ecology of palm weevils Curculionidae Rh  cJune  a153-1670 v793 aPalm weevils in the subfamily Rhynchophorinae (Curculionidae) (Rhynchophorus spp., Dynamis borassi, Metamasius hemipterus, Rhabdoscelus obscurus, and Paramasius distortus) use male-produced aggregation pheromones for intraspecific chemical communication. Pheromones comprise 8, 9, or 10 carbon, methyl-branched, secondary alcohols. (4S,5S)-4-Methyl-5-nonanol (ferrugineol) is the major aggregation pheromone for R. ferrugineus, R. vulneratus, R. bilineatus, M. hemipterus, and D. borassi and a minor component for R. palmarum. (5S,4S)-5-Methyl-4-octanol (cruentol), (3S,4S)-3-methyl-4-octanol (phoenicol), and (4S,2E)-6-methyl-2-hepten-4-ol (rhynchophorol) are the main aggregation pheromones for R. cruentatus, R. phoenicis, and R. palmarum, respectively. Plant kairomones strongly enhance pheromone attractiveness but none of the identified volatiles, such as ethyl acetate, ethyl propionate, or ethyl butyrate are as synergistic as fermenting plant (palm or sugarcane) tissue. Studying orientation behavior of foraging weevils to semiochemical devices helped to design and test traps for weevil capture. Generally, 3 mg per day of synthetic pheromone (with non-natural stereoisomers being benign) plus insecticide-treated plant tissue constitute highly attractive trap baits. Potential exists for pheromone-based mass-trapping of weevils to reduce their populations and the spread of the weevil-vectored red ring disease, for monitoring their population dynamics to facilitate pest management decisions, and for detection and possible interception of non-native weevils at ports of entry.10aBehaviour10aChemical signals10aHosts10aparasite10aRhynchophorinae1 aGiblin-Davis, R., M.1 aOehlschlager, A., C.1 aPerez, A.1 aGries, G.1 aGries, R.1 aWeissling, T., J.1 aChinchilla, C., M.1 aPena, J., E.1 aHallett, R., H.1 aPierce, H., D.1 aGonzalez, L., M.  u<Go to ISI>://ZOOREC:ZOOR13300017286
