Monitoring western corn rootworm (Coleoptera: Chrysomelidae) susceptibility to carbaryl and cucurbitacin baits in the areawide management pilot program.
Areawide pest management involves the uniform application of a pest control strategy over wide geographic areas. Therefore, these programs are likely to impose intense selective pressures, and the risk for resistance development among pest species for which areawide management programs are implemented is likely to be high. Pilot studies for areawide management of western corn rootworm, Diabroti...

متن کاملToxicity of insecticide-bait mixtures to insecticide resistant and susceptible western corn rootworms (Coleoptera: Chrysomelidae)
Organophosphate resistant and susceptible populations of the western corn rootworm, Diabrotica virgifera virgifera LeConte. were subjected to adult feeding bioassays with different combinations of insecticide and a cucurbitacin bait. Five technical grade insecticides (methyl-parathion, carbaryl, fipronil, bifenthrin and indoxacarb) were used in combination with Invite ECt as the feeding stimula...
متن کاملSusceptibility of Nebraska Western Corn Rootworm (Coleoptera: Chrysomelidae) Populations to Bt Corn Events.
Transgenic plants have been widely adopted by growers to manage the western corn rootworm, Diabrotica virgifera virgifera LeConte, in field corn. Because of reduced efficacy in some Nebraska fields after repeated use of Cry3Bb1-expressing hybrids, single plant bioassays were conducted in 2012 and 2013 to characterize the susceptibility of western corn rootworm populations to the rootworm-active...
متن کاملCytochrome P450-Mediated N-Demethylation Activity and Induction in Insecticide-Resistant and Susceptible Western Corn Rootworm Populations (Coleoptera: Chrysomelidae)
Elevated cytochrome P450 monooxygenase-based metabolism is associated with carbaryl and methyl parathion resistance in western corn rootworm (Diabrotica virgifera virgifera LeConte) populations in the state of Nebraska. The objectives of this study were to identify potential differences in cytochrome P450 in resistant and susceptible rootworm populations using the model substrate 4-chloro-N-met...
