In order to give full play to the role of chemical control in comprehensive pest control and to find new safe and effective insecticides, we started to cooperate with relevant units in 1980 to eliminate 14 kinds of agricultural pests by over 40 insecticidal plants, including Meliaceae , Antifeedant, systemic, touch and control of insect growth and development of a series of indoor and field experiments, and achieved some gratifying results.
