Abstract
A 100-fold difference in toxicity was obtained when cyhexatin was tested with a slide-dip method on a laboratory-pressured cyhexatin-resistant (ShJp) and susceptible (S) strain of twospotted spider mite, Tetranychus urticae Koch. No difference in penetration or metabolism of cyhexatin was observed between the two strains of mites. A 6.5-fold difference in cyhexatin inhibition of oligomycin-sensitive (OS) Mg2+ ATPase activity was found between the two strains of mites. An altered target site appears to be responsible in part for cyhexatin resistance.This publication has 0 references indexed in Scilit:
