Side effects of five new acaricides on the predator Galendromus occidentalis (Acari, Phytoseiidae).
Contact and residual effects of etoxazole, spiromesifen, fenpyroximate, bifenazate, and acequinocyl on life parameters of Galendromus occidentalis (Nesbitt) were studied under laboratory conditions. Fenpyroximate reduced adult female longevity to <24 h, and no eggs were laid. Longevity of spiromesifen- and acequinocyl-treated adult females was reduced to 4 days, with observed reductions in fecundity and fertility. Etoxazole and bifenazate did not reduce adult female longevity, but progeny were not produced.
