The use of sex pheromones to collect males is economical; however, pre-exposure to sex pheromones may affect male mating behavior, and would thus reduce the effectiveness of the SIT programs. Males exposed to sex pheromone may become attractive to other males due to pheromone adsorption on their body impregnation, prevent mating and reduce the dispersal of sterile males. We examined the effect of pre-exposure to sex pheromone on the mating behavior of male sweetpotato weevil Cylas formicarius. Pre-exposure to high-dose sex pheromone for 24 h did not affect the male mating behavior of C. formicarius, and the exposed males did not attract other males. These results suggest that male C. formicarius that were collected from a mass-rearing facility using sex pheromone can be effectively used in SIT programs.10aCylas formicarius1 aKuriwada, Takashi1 aKumano, Norikuni1 aShiromoto, Keiko1 aHaraguchi, Dai  uhttps://weevil.myspecies.info/pre-exposure-sex-pheromone-did-not-affect-mating-behavior-sweetpotato-weevil-cylas-formicarius01324nas a2200181   4500008004500000020001400045245009500059210006900154260001400223300001200237490000700249520068200256653002000938100002900958700002800987700001601015856011101031       2008                        Engldsh    a1612-475800aFirst record of the ambrosia beetle, Monarthrum mali (Curculionidae, Scolytinae) in Europe0 aFirst record of the ambrosia beetle Monarthrum mali Curculionida  cSeptember  a175-1780 v813 aDuring research conducted in northern Italy for the State Forestry Service LIFE Nature project, a single male specimen of the scolytine ambrosia beetle Monarthrum mali (Fitch) was collected in an ethanol-baited window flight trap. Trapping started in 2005, but the species was first collected in August 2007, suggesting that the establishment of M. mali in northern Italy is very recent. Monarthrum mali represents the second North American ambrosia beetle to be introduced to Europe, and joins Phloeotribus limnaris and Xylosandrus crassiusculus as recent scolytine introductions to Europe via Italy that pose potential threats to Europe's nurseries, orchards and plantations.10aMonarthrum mali1 aKirkendall, Lawrence, R.1 aDal Cortivo, Marialuisa1 aGatti, Enzo  uhttps://weevil.myspecies.info/first-record-ambrosia-beetle-monarthrum-mali-curculionidae-scolytinae-europe02489nas a2200193   4500008004100000020001400041245012500055210006900180260001000249300001000259490000700269520179300276653003002069100001702099700001502116700001802131700001102149856013502160       2011                        eng d  a1612-475800aEffect of host plants on development and reproduction of Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae)0 aEffect of host plants on development and reproduction of Rhyncho  cMarch  a33-390 v843 aThe development, survivorship and reproduction of red palm weevil Rhynchophorus ferrugineus, reared on five ornamental palm slices, were studied in the laboratory at constant temperature of 26[degree]C. The developmental time of R. ferrugineus was 68.8 days on Washington palm (Washingtonia filifera), 74.1 days on Canary Island date palm (Phoenix canariensis), 82.1 days on Chusan palm (Trachycarpus fortunei), 85.4 days on pindo palm (Butia capitata) and 90.6 days on silver date palm (Phoenix sylvestris), respectively, and the developmental time on silver date palm was significantly longer than that on the other plants. The survival of immature R. ferrugineus ranged from 25.0 to 38.3%. Most mature larvae began to pupate at eighth-instar on Canary Island date palm and Washington palm, while on Chusan palm, Pindo palm and silver date palm, most of them began to pupate at ninth-instar. The mean lifetime fecundity of R. ferrugineus on Canary Island date palm, Chusan palm, Pindo palm, Washington palm and silver date palm was 267.8, 134.0, 109.8, 216.0, and 131.4 eggs, respectively, and lifetime fecundity on Canary Island date palm and Washington palm was significantly greater than that on the other plants. The intrinsic rate of natural increase (r m ), net reproductive rate (R 0) and mean generation time (T) were 0.038, 78.3 and 115.0 days on Canary Island date palm, 0.028, 33.1 and 125.5 days on Chusan palm, 0.029, 40.9 and 128.2 days on Pindo palm, 0.041, 64.0, 101.4 days on Washington palm, and 0.025, 30.6, 135.6 days on silver date palm, respectively. Based on population growth parameters, it is concluded that Canary Island date palm and Washington palm were the more suitable host plants and silver date palm was the least suitable host plant for R. ferrugineus.10aRhynchophorus ferrugineus1 aJu, Rui-Ting1 aWang, Feng1 aWan, Fang-Hao1 aLi, Bo  uhttps://weevil.myspecies.info/effect-host-plants-development-and-reproduction-rhynchophorus-ferrugineus-olivier-coleoptera-curculi01885nas a2200169   4500008004100000020001400041245014200055210006900197260000800266300001100274490000700285520122300292100002401515700001801539700002301557856013501580       2007                        eng d  a1612-475800aInsect natural enemies of Ips typographus (L.)

Only Thanasimus spp. (Col., Cleridae) was significantly more abundant in managed forest, possibly because it was favored by the more open, sunny stands. However, the experiment was performed in stands where spruce is only a minor component and during the non-epidemic phase of the bark beetle population, so further experiments may be necessary to determine if the effects of sanitary fellings are greater in different forest types and at different stages of the population cycle1 aHilszczanski, Jacek1 aGibb, Heloise1 aBystrowski, Cezary  uhttps://weevil.myspecies.info/insect-natural-enemies-ips-typographus-l-coleoptera-scolytinae-managed-and-unmanaged-stands-mixed-lo01260nas a2200193   4500008004100000020001400041245010400055210006900159260001300228300001000241490000700251520058200258653002400840100002500864700002100889700002000910700001700930856011900947       2007                        eng d  a1612-475800aFirst record of the wood boring weevil, Pentarthrum huttoni, in Austria (Coleoptera: Curculionidae)0 aFirst record of the wood boring weevil Pentarthrum huttoni in Au  cFebruary  a59-610 v803 aThe wood boring weevil, Pentarthrum huttoni Wollaston, is reported for the first time from Austria. It was recorded from coffins in the crypt of St. Michael's church in the centre of Vienna. Extensive tunnelling of the larvae and surface damage by the adults caused disintegration of the historically significant wooden 18th century coffins. Beetles were also detected in rotten cardboard on the loamy soil of the crypt. Infestation by this Cossonine weevil is promoted by the very damp conditions in the crypt, a consequence of the closure of ventilation funnels in the 1940s.10aPentarthrum huttoni1 aHalmschlager, Erhard1 aLadner, Christof1 aZabransky, Petr1 aSchopf, Axel  uhttps://weevil.myspecies.info/first-record-wood-boring-weevil-pentarthrum-huttoni-austria-coleoptera-curculionidae02249nas a2200169   4500008004100000020001400041245015200055210006900207260001000276300001000286490000700296520157600303653002001879100002101899700002401920856013501944       2011                        eng d  a1612-475800aBreeding performance of the second generation in some bivoltine populations of Ips typographus (Coleoptera Curculionidae) in the south-eastern Alps0 aBreeding performance of the second generation in some bivoltine   cMarch  a15-230 v843 aThe spruce bark beetle, Ips typographus, is one of the most extensively studied European forest pests. Gaps exist in the knowledge about second generation breeding performance in bivoltine populations. In this study, the breeding performance of the second generation was evaluated in three bivoltine populations of I. typographus in the SE Alps. Length of the maternal galleries (from 40.5 to 44.8 mm), population growth rate (PGR; from 0.7 to 3.6), and emerged adults per m2 (from 669 to 1,570 insects/m2) varied among populations and were negatively correlated with bark colonisation density. Pheromone traps set up in the three investigated forests differed in the number of trapped beetles, with mean captures ranging between 5,310 and 19,850 insects per trap. The populations giving the highest captures in the traps showed the lowest bark colonisation density (248 vs. 489 maternal galleries per m2) and the best breeding performance. The populations of parasitoids and predators corresponded to just 1[long dash]9 and 2[long dash]10% of the emerging I. typographus adults, respectively, and phloem temperature never reached thresholds lethal to I. typographus. Interspecific competition was negligible, whereas intraspecific competition was found to be the main factor affecting the breeding performance of the second generation, although with different intensity according to the colonisation density. It is hypothesised that competition with the first generation and spring precipitation influence the number of suitable hosts available to the second generation.10aIps typographus1 aFaccoli, Massimo1 aBernardinelli, Iris  uhttps://weevil.myspecies.info/breeding-performance-second-generation-some-bivoltine-populations-ips-typographus-coleoptera-curculi02410nas a2200157   4500008004100000020001400041245017100055210006900226260000800295300001200303490000700315520175600322100001702078700002202095856013502117       2011                        eng d  a1612-475800aDetermining suitability of thermal development models to estimate temperature parameters for embryonic development of Sitona lepidus Gyll. (Coleoptera: Curculionidae)0 aDetermining suitability of thermal development models to estimat  cSep  a303-3110 v843 aThe clover root weevil, Sitona lepidus Gyll. is a pest of clovers (Trifolium spp.), particularly white clover (T. repens). Larva feeding severely impairs the capacity of white clover to fix atmospheric nitrogen, by attacking the nitrogen-fixing root nodules. Development of the egg stage was studied at six different constant temperatures ranging from 9 to 30[degree]C to improve the basis for phenological forecasts. Development occurred over the entire range of temperatures, although hatching percentage at 30[degree]C was only 24.4% compared to 90.1% at 28.5[degree]C. Developmental time decreased with increase in temperature from 9 to 28.5[degree]C but increased markedly at 30[degree]C. At 28.5[degree]C, the embryo development period was the shortest (10.35 days); whereas at 9[degree]C, this parameter was the longest (55.08 days). Using linear regression, the lower threshold temperature was calculated 4.38[degree]C and the thermal constant was 236.45 degree-days. The relationship between constant temperature and developmental rate was evaluated using nine models. The suitability of the models was evaluated based on eight indicators (R 2, RSS, R adj 2, AIC, BIC, AICC, W j, and Z i ). Of the nonlinear models, the Logan-6, Sharpe and DeMichele, and Lactin models were the most accurate at calculating t opt of 27, 27.50, and 28[degree]C, respectively. The results suggest that of the three models (Lactin, Briere, and Hilbert and Logan), that estimated critical temperatures, (t min, t opt, and t max), Lactin gave the most suitable fit of data. This response of S. lepidus to temperature can be used for developing phonological models to predict the timing of egg hatch which are important for management programs targeting the weevil.1 aArbab, Abbas1 aMcNeill, Mark, R.  uhttps://weevil.myspecies.info/determining-suitability-thermal-development-models-estimate-temperature-parameters-embryonic-develop
