文摘The sensitivity of laboratory reared Anastatus japonicus adults to field concentrations of ten bio-insecticides was evaluated by toxic paper method. The results indicated that NPV, B. t aizawai, B. t qiansheng, B. t chongwen and plant derived insecticides, such as neem oil and, cineol, were harmless to A. joponicus.; B. t and rotenone had sonic toxicity., but were comparatively safe while trichlorfon was highly toxic to A japonicus. In order to reduce the harmful effects of insecticides to A japonicus, the use of some highly toxic insecticides must stop and some reasonably low-toxi insecticides, especially biological insecticides can be used when parasites are released to control insect pests.
