The effects of several pesticides on the survival of eggs and adult females of three predacious mites, Phytoseiulus persimilis Athias-Henriot, Amblyseius californicus (McGregor) and A. womersleyi Schicha, were evaluated by using a spraying tower in the laboratory. Eleven insecticides, four acaricides, two fungicides were harmless to the three predacious mites. These chemicals seem to be usable in IPM systems with those natural enemies.
