Acoustic detection can be used to assess the likelihood of insect infestations in bags of grain, flour, and other commodities that are stored in small holdings in developing countries, enabling rapid targeting of treatments. A portable postharvest insect detection system was developed with the goal to provide low-cost capability to acoustically assess infestations in small-scale storage facilities. Electret microphones input pest insect sounds to a 32-bit microcontroller platform that digitized and stored the signals on a digital memory card transferable to a portable laptop computer. The insect sounds then were analyzed by custom-written software that matched their spectra to those of known pests. Infestations of Sitophilus oryzae (L) in 2.6-kg bags could be detected down to densities of 1.9 adults\/kg in grain and Tribolium castaneum (Herbst) down to 3.8 adults\/kg in flour in laboratory settings. Also, differences in the rates of sounds per insect in treatments with different numbers ranging from 5 to 50 insects suggested that the sound rates of adults of different species at different population densities may be noticeably affected by aggregation pheromones or other behaviorally active semiochemicals. Further testing is needed but previous experience with acoustic detection systems suggests that the prototype has potential for use in small storage facilities where early detection of infestations is difficult to provide.<\/jats:p>","DOI":"10.1093\/jee\/toaa203","type":"journal-article","created":{"date-parts":[[2020,8,14]],"date-time":"2020-08-14T19:29:06Z","timestamp":1597433346000},"page":"3004-3010","source":"Crossref","is-referenced-by-count":25,"title":["Performance of a Low-Cost Acoustic Insect Detector System with <i>Sitophilus oryzae<\/i> (Coleoptera: Curculionidae) in Stored Grain and <i>Tribolium castaneum<\/i> (Coleoptera: Tenebrionidae) in Flour"],"prefix":"10.1093","volume":"113","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3369-8110","authenticated-orcid":false,"given":"R W","family":"Mankin","sequence":"first","affiliation":[{"name":"United States Department of Agriculture, Agricultural Research Service Center for Medical, Agricultural and Veterinary Entomology (CMAVE), Gainesville, FL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E","family":"Jetter","sequence":"additional","affiliation":[{"name":"Department of Public Health, University of Florida, Gainesville, FL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Rohde","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Yasir","sequence":"additional","affiliation":[{"name":"Department of Entomology, University of Agriculture, Faisalabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,9,23]]},"reference":[{"key":"2020120907235636200_CIT0001","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1016\/j.jspr.2018.03.002","article-title":"On-farm comparison of different postharvest storage technologies in a maize farming system of Tanzania central corridor","volume":"77","author":"Abass","year":"2018","journal-title":"J.
