Abstract:The topical I.D30 values of 34 analogues of dimethoate were determined using dimethoate-resistant (R) and susceptible (S) strains of ,Musca domestica L. Dimethoate and dimethoxon were the most toxic to R and S strains of house flies. Resistance was demonstrated in the R strain to all the compounds tested. In no case was resistance circumvented by using the various analogues. Studies with ,N-alkyl and N,N-dialkyl analogues of dimethoate demonstrated that and amidase was not involved in the resistance mechanism. Resistance generally was higher to the phosphates than to their phosphorothionate counterparts, indicating that the resistance mechanism probably was associated with the degradation of the phosphate analogues.
