Abstract
To construct a conservation biological control program for open field eggplant production, the effects of fenpyroxymate-buprofezin, indoxacarb MP, pyrifluquinazon, and permethrin on the twenty-eight-spotted ladybird (TESL) and Orius spp. were investigated in an eggplant field. Control effects of the four insecticides on TESL were detected at a high level. Indoxacarb MP had no effect on Orius spp. Fenpyroxymate-buprofezin affected Orius spp. about 2 weeks after treatment. Pyrifluquinazon affected Orius spp. 3 days after treatment, but the effective period was less than 1 week. Permethrin affected Orius spp. for more than 2 weeks.
