Abstract
Twelve populations of the predatory phytoseiid mite, Amblyseius fallacis Garman were tested for susceptibility to the pyrethroid, permethrin, and the organophosphorous insecticide, azinphosmethyl. Most populations had LC 50 's considerably below field rates of permethrin. Two populations had LC 50 's approaching field rates; these populations showed some level of resistance and could form the basis for further selections for highly resistant predators. Permethrin LC 50 's showed no correlation with azinphosmethyl LC 50 's.This publication has 0 references indexed in Scilit:
