Researchers in California tested several common insecticide baits used for management of German cockroaches (Blattella germanica) and found evidence of resistance to all but one bait in several field-caught populations.
Testing field-caught mosquitoes for insecticide resistance is a critical effort in the fight against malaria and other vector-borne diseases. Researchers in Thailand say a "forced oviposition" method has proven successful in inducing field-caught Anopheles mosquitoes to lay eggs and spawn lab populations big enough for insecticide-resistance testing.
Cotton and corn are threatened by growing resistance in the pest Helicoverpa zea (a.k.a. bollworm or corn earworm) to the insecticidal properties of Bt crops. Two researchers identify contributing factors and identify insecticide resistance management practices that could help slow the problem.
Organized by the ESA Student Affairs Committee, this symposium at Entomology 2018 will gather a variety of perspectives on the latest research and strategies for managing insecticide resistance in mosquitoes, bed bugs, moths, and more.
