Abstract
The present study was directed to evaluate toxicity of six chemical of different mode of action, four pesticides (abamectin, ethion, chlorfenapyr and cyhalothrin), one mineral oil (Nat 1), and one plant extract (black cumin) against the adult female mites Tetranychus utricae and their predatory mites Amblyseius fallacies and phytoseiulus persimilis using standardized method for bioassay. The effects of sublethal doses of these chemicals on some biological aspects of mites and their predators were also evaluated. A bamectin has a special position in integrated mite management while chyalothrin is a promising compound in mite control programs. The contaminated prey egg consumption was different according to the chemical used.
