2007 Annual Report
Application of acoustic technology as an IPM tool: Many invasive and established pests live in conditions that make them difficult to locate such as in wood or underground. New analyses of temporal patterns of feeding sounds were developed that help distinguish feeding sounds made by wood infesting beetles (Asian longhorned beetle and red palm weevil) and subterranean grubs from background noises. The capability to detect and monitor hidden infestations can direct control measures to the specific spots where pests occur strengthen quarantines, and minimize the destruction of commodities suspected of exposure to these hidden insects. Research addresses NP-304, Crop Protection and Quarantine, and the Problem Statement associated with Action Plan Component V: Pest Control Technologies.
Cotton Infested by Corn Strain fall army worm moths: There are two different strains of fall army worm with different hosts, behaviors and responses to insecticides, including Bt genes inserted into genetically modified cotton. Larvae and adult fall army worms were subjected to carbon isotope analysis and to molecular analysis of strain-specific genes. It was found that the majority of fall armyworm adults present during the early cotton season arise from corn, sorghum, etc. and that the host strain that later develops on cotton is the “corn” and not the “rice”. Knowing where multiple host-pests, like fall army worm, seasonally occur can help target proactive control measures to prevent their expansion into additional crops and direct what might be the best control technique to employ. Research addresses NP-304, Crop Protection and Quarantine, and the Problem Statement associated with Action Plan Component II: Biology of Pests and Natural Enemies.
Flower found to attract important family of natural enemies: The Braconidae are small wasps whose larvae develop in and kill many insect species, including major agricultural pests. Pest mortality might be increased if these insects could be concentrated and maintained by the presence of adult foods such as flowers. Traps baited with flowering plants found that one species in particular, alyssum, attracted several subfamilies of braconids. This flower might be advantageously planted along the margins of early season crops to suppress caterpillars. Research addresses NP-304, Crop Protection and Quarantine, and the Problem Statement associated with Action Plan Component II: Biology of Pests and Natural Enemies (Microbes) and III: Plant, Pest, and Natural Enemy Interactions, and Ecology.
