Abstract
Two strains of the two-spotted spider mite, Tetranychus urticae, were 20–40 times more tolerant to permethrin than 3 strains of the phytoseiid Metaseiulus occidentalis. One predator colony was 2 times more susceptible to permethrin than the other two. The authors note that very low rates of permethrin might preserve M. occidentalis populations in the field.This publication has 1 reference indexed in Scilit:
