(Coleoptera: Curculionidae), Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), and Stegobium paniceum (L.) (Coleoptera: Anobiidae), and two urban pests. Blattella germanica (L.) (Blattodea: Blattellidae) and Cimex lectularius L. (Hemiptera: Cimicidae), were monitored individually by infrared sensors, microphones, and a piezoelectric sensor in a small arena to evaluate effects of insect locomotory behavior and size on the ability of an inexpensively constructed instrument to detect insects and distinguish among different species. Adults of all species could be detected when crawling or scraping. The smallest insects in the study, first-fourth-instar C. lectularius nymphs, could not be detected easily when crawling, but could be detected when scraping. Sound and vibration sensors detected brief, 3-10-ms impulses from all tested species, often grouped in distinctive trains (bursts), typical of impulses in previous acoustic detection experiments. To consider the potential for targeting or focusing detection on particular species of interest, indicators were developed to assess the likelihood of detection of C. lectularius. Statistically significant differences were found between C. lectularius and other species in distributions of three measured variables: infrared signal durations, sound impulse-burst durations, and sound pressure levels (energy) of impulses that best matched an averaged spectrum (profile) of scraping behavior. Thus, there is potential that signals collected by an inexpensive, polymodal-sensor instrument could be used in automated trapping systems to detect a targeted species, 0.1 mg or larger, in environments where servicing of traps is difficult or when timeliness of trapping information is important.10aSitophilus oryzae1 aMankin, R., W.1 aHodges, R., D.1 aNagle, H., T.1 aSchal, C.1 aPereira, R., M.1 aKoehler, P., G.  uhttps://weevil.myspecies.info/acoustic-indicators-targeted-detection-stored-product-and-urban-insect-pests-inexpensive-infrared--002337nas a2200217   4500008004500000020001400045245016200059210006900221260000900290300001200299490000700311520153700318653003001855100001901885700001601904700001701920700001501937700001601952700001601968856013501984       2008                        Engldsh    a0015-404000aTemporal and spectral features of sounds of wood-boring beetle larvae: identifiable patterns of activity enable improved discrimination from background noise0 aTemporal and spectral features of sounds of woodboring beetle la  cJune  a241-2480 v913 aRhynchophorus (curculionid) larvae produce economic damage to ornamental and date palm crops that could be mitigated significantly by early detection and treatment. Acoustic technology enables early detection, but often it is difficult to distinguish insect sounds from background noise containing energy at the resonant frequencies of stiff, fibrous structures in trees and other plants. Tests were conducted with currently available acoustic instrumentation and software to assess the capability of these methods to discriminate curculionid, cerambycid, and buprestid larval sounds from background noise in woody structures. An approach to the discrimination problem is to monitor the temporal patterns of the 3-10-ms sound impulses produced by locomotory and feeding activities. Playback and computer analyses of larval sounds revealed trains of impulses separated by intervals of less than 500 ms that experienced listeners frequently use as indications of potential insect sounds. Further analyses identified a subgroup of trains, denoted as bursts, containing > 6 and 200 impulses, which occurred frequently when larvae were present but only rarely when larvae were absent. The incorporation of bursts into the analysis process significantly improved the capability to distinguish sounds produced by beetle larvae from background noise when these insects were hidden in stiff, fibrous structures, and likely will be of assistance also in other applications where consistent activity patterns of hidden pests can be identified.10aRhynchophorus ferrugineus1 aMankin, R., W.1 aMizrach, A.1 aHetzroni, A.1 aLevsky, S.1 aNakache, Y.1 aSoroker, V.  uhttps://weevil.myspecies.info/temporal-and-spectral-features-sounds-wood-boring-beetle-larvae-identifiable-patterns-activity-ena-002337nas a2200217   4500008004500000020001400045245016200059210006900221260000900290300001200299490000700311520153700318653003001855100001901885700001601904700001701920700001501937700001601952700001601968856013501984       2008                        Engldsh    a0015-404000aTemporal and spectral features of sounds of wood-boring beetle larvae: identifiable patterns of activity enable improved discrimination from background noise0 aTemporal and spectral features of sounds of woodboring beetle la  cJune  a241-2480 v913 aRhynchophorus (curculionid) larvae produce economic damage to ornamental and date palm crops that could be mitigated significantly by early detection and treatment.

(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.
