Abstract
Four resistant strains of the predacious mite Amblyseius gossipi as well as a susceptible strain were chosen to study the effect of resis­tance on life span, fecundity, sex ratio and food consumption. The re­sults showed that the egg incubation period of the resistant strains in­creased significantly in comparison with the susceptible strain. The resistant strains had longer laryal stage, lower fecundity and higher fe­male ratio. Although the feeding capacity decreased as well, the resist­ant strains could withstand the frequent use of pesticides, and could survive in conditions in which their number is very low.
