| 摘 要： | 采用药膜法测定了０．５％楝素杀虫乳油对广赤眼蜂，暝黄赤眼蜂和松毛虫赤眼蜂的毒。结果表明，三种赤肯蜂对０．５％楝素杀虫乳油的敏感性均显著低于对照药剂溴氰菊酯约６０倍以上，其ＬＣ５０分别为１４０．０７，５０４．０７和５４．５４ｍｇ／Ｌ。田间药效试验证明，０．５％楝素杀虫乳油对菜青虫绒茧蜂，蚜茧蜂及瓢虫，食蚜蝇等昆虫天敌无明显影响。

| Abstract: | Toxicity of Toosendanin 0. 5 EC to Trichogramma evanescens Westwood, T. confusum Viggiani,T. dendrolimi Matsumura were measured by means of exposing to pesticide residue. The resultsshowed that susceptability of three inseet natural enemies to Toosendanin 0. 5 EC were all about60 times lower than decamethrin and with LC50140.07, 504. 07 and 54. 54 mg/L respectively.Results of field testing also showed that Toosendanin 0. 5 EC had no obvious effects to Apanteles gleartus Linnaeus, Diaeretiella rapae M' Intosh, Coccinellidae spp. and Syrphidao spp. ete. |
