| 摘 要： | 采用管测药膜法测定了4种新型杀虫剂及7种常用杀虫剂对螟黄赤眼蜂的急性毒性，并参考各药剂的田间推荐剂量进行了安全性评价，旨在为农药的安全合理使用提供科学依据，同时为协调生物与化学防治有害生物的关系提供理论指导。结果表明，供试4种新型杀虫剂中，仅乙基多杀菌素对螟黄赤眼蜂成蜂表现为中等风险性，溴氰虫酰胺、三氟苯嘧啶和氟苯虫酰胺的表现相对安全；7种常用杀虫剂中，毒死蜱对螟黄赤眼蜂成蜂表现为高风险性，阿维菌素、吡虫啉和烯啶虫胺表现为中等风险性，氯虫苯甲酰胺、茚虫威和甲维盐的表现相对安全。

| Abstract: | The acute toxicity of four new insecticides and seven conventional insecticides to natural enemy Trichogramma chilonis was measured with the method of film residue in a tube, and safety assessment was conducted according to the field recommended dosages. Results showed that among the four new insecticides, Spinetoram had exhibited a medium risk on T. chilonis adults while Cyantraniliprole、Triflumezopyrim and flubendiamide exhibited relative safety; Among the seven conventional insecticides, Chlorpyrifos had exhibited a high risk on T. chilonis adults while Abamectin, Imidacloprid and Nitenpyram was defined as a medium risk, Chlorantraniliprole, Indoxacarb, and Emamectin benzoate exhibited relative safety. Our results provided a valuable reference to the applications of chemical control and nature enemy control of insect pests. |
