Susceptibility of the predatory mite, Phytoseiulus persimilis to 8 insecticides was evaluated. In treatments with insecticides tested, 78-92% of adult female predators survived after 168 hrs after treatment. Adult female predators treated with insecticides tested produced 62.6-93.4% as many eggs as did control females and eclosion of eggs deposited by treated predators was not affected. Moreover, hatch percentage of P. persimilis eggs and survival of nymphs were not seriously affected by exposure to the insecticides tested. Immatures of P. persimilis survived on the leaf disc treated with insecticides tested and 98-100% of immature predators reached adulthood. Based on the results, insecticides tested are expected to be promising candidates for use in integrated pest management program with P. persimilis.
