Background. The presence in interline hybrids two-spotted spider mite Tetranychus urticae Koch two genes determining resistance to acaricides of various chemical classes significantly increases their sensitivity to the action of each these toxicants. Materials and methods. The resistant and susceptible to malathion, bifenthrin and abamectin inbred lines of spider mite by disruptive selection cycles were obtained. The toxicological tests were performed by diagnostic concentrations of acaricides. The protein marker gene of resistance to malathion was determined by poliacrylamide disc-electrophoresis. Results. The epistatic interaction of resistance genes to different acaricides is not manifestation at the stages of transcription and translation of genetic information. Conclusion. The epistatic effect of another gene on the resistance gene to the current acaricide is a different consequence of metabolism processes encoded by each gene at the stage of phenotypic regulation.
