영문 초록

The susceptibility of Neoseiulus womersleyi, a natural enemy of Tetranychus kanzawai, to extracts of Melia azedarach, Piper nigrum, and Syringa velutina and their mixtures was evaluated. In the treatments with the plant extracts tested, 74-90% of the adult female predators survived at 7 days after treatment. The adult female predators treated with the plant extracts tested produced 65.5-82.2% as many eggs as did the control females and the eclosion of eggs deposited by the treated predators was not affected. Moreover, the treatments of the plant extracts tested showed no toxic effect on the N. womersleyi eggs and larvae after hatching. The survival of the N. womersleyi nymphs was not seriously affected by their exposure to the plant extracts tested. The immature N. womersleyi survived on the leaf disc treated with the plant extracts tested and 76-94% of the immature predators reached adulthood. These results suggest that the extracts of M. azedarach, P. nigrum, S. velutina and their mixtures are promising candidates for use in an integrated management program where N. womersleyi is a native natural enemy.
