Abstract:
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.
