Response of Three Populations of Liriomyza Trifolii (Diptera:Agromyzidae) to Topical Applications of Permethrin and Bifenthrin
Abstract
Susceptibility to the pyrethroid insecticides permethrin and bifenthrin was determined for three populations of Liriomyza trifolii (Burgess) originally collected from commercial chrysanthemums in California, Florida, and Maryland. The Maryland population was significantly more resistant to both compounds than either the California or Florida population. Susceptibilities may have been affected by the number of generations populations were maintained as laboratory colonies.Downloads
