Inheritance and persistence of permethrin resistance in the predatory mite, Amblyseius fallacis (Acarina: Phytoseiidae)
Environmental Entomology 12 (1), 215-218
Abstract: Genetic analysis of permethrin resistance in the predatory mite, Amblyseius fallacis, indicated a polygenic, recessive basis for resistance. In the laboratory, with and without the immigration of resistant biotypes, permethrin resistance did not decline in mites left untreated over 25 generations. This was comparable to the stability of azinphosmethyl resistance in this same strain. In the field when influenced by large immigrant populations of susceptible biotypes, permethrin-resistant predators persisted initially after a permethrin spray applied in an apple orchard during the early growing season, but by late fall they were flooded out and resistance was diminished through hybridization. The implications of these results for management of S-P-resistant A. fallacis in apple integrated pest management systems are discussed.
