摘　　要：在室内测定了6种杀虫剂对橡副珠蜡蚧3龄若虫和斑翅食蚧蚜小蜂成虫的毒力。结果表明,6种农药对橡副珠蜡蚧和斑翅食蚧蚜小蜂的选择毒性为:溴氰菊酯>三氟氯氰菊酯>敌介灵>甲胺磷>啶虫脒>毒死蜱,其中溴氰菊酯的选择倍数最高为35.59,毒死蜱的选择倍数最低,仅为0.0006。建议在天敌较多的季节,可优先选用溴氰菊酯防治橡副珠蜡蚧,三氟氯氰菊酯可以与溴氰菊酯交替使用。Toxicity of 6 insecticides to Coccophagus ceroplastae and Parasaissetia nigra was studied in the laboratory. The result showed that the order of selective toxicity was： deltamethrin 〉 lambda-cyhalothrin 〉 chlorpyrifos ＆ cypermethrin 〉 acephate 〉 acetamiprid 〉 chlorpyrifos. Deltamethrin showed the highest selective toxicity between Aneristus ceroplastae and Parasaissetia nigra and the lambda-cyhalothrin came second. The rest of four insecticides （chlorpyrifos, cypermethrin, acephate, acetamiprida） had no selection protection to Aneristus ceroplastae. It is recom- mended that deltamethrin should be selected to control Parasaissetia nigra during seasons when Aneristus ceroplastaea and other natural enemies are relatively numerous and lambda-cyhalothrin may be alternatively used.
