(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--002644nas a2200217   4500008004100000020001400041245016100055210006900216260000800285300001400293490000800307520184400315653002202159100001902181700001902200700001802219700001402237700002002251700002002271856013502291       2010                        eng d  a0022-049300aAcoustic Indicators for Targeted Detection of Stored Product and Urban Insect Pests by Inexpensive Infrared, Acoustic, and Vibrational Detection of Movement0 aAcoustic Indicators for Targeted Detection of Stored Product and  cOct  a1636-16460 v1033 aCrawling and scraping activity of three stored-product pests, Sitophilus oryzae (L.)
