Resistance of horn flies (Diptera: Muscidae) to permethrin and fenvalerate






Journal of Economic Entomology 78(2): 402-406

Resistance of horn flies (Diptera: Muscidae) to permethrin and fenvalerate

The susceptibilities of Haematobia irritans from 4 locations to fenvalerate and permethrin were compared by exposure of adults. The flies were collected from dairy cattle at 2 locations in Okeechobee County, Florida. One group (FLA) was collected from breeding dairy heifers treated the previous year and the other (FLB) from untreated yearling dairy heifers about 1 km from the breeding heifers. Collections in Texas were made from beef cattle (TX) and from a laboratory strain (LAB).
