摘　　要：采用喷雾塔喷雾法测定高效氯氟氰菊酯、高效氯氰菊酯等7种药剂及其加入有机硅表面活性剂后对螺旋粉虱成虫的杀虫活性,以期明确有机硅表面活性剂对杀虫剂的增效作用。结果表明,高效氯氟氰菊酯、高效氯氰菊酯、阿维菌素、甲氨基阿维菌素苯甲酸盐、联苯菊酯、啶虫脒和杀虫单等单剂对螺旋粉虱成虫药后24h的LC50值分别为5.7405、8.6831、16.8958、19.9352、25.0438、41.9243、101.0852mg/L,加入0.1%有机硅后LC50值分别为0.9452、1.7138、13.2780、10.7363、7.6237、7.5898、29.9689mg/L,毒效比分别为6.07、5.07、1.27、1.86、3.28、5.52、3.37。表明有机硅表面活性剂对所选药剂的触杀作用均有不同程度的增效,其中对高效氯氟氰菊酯的增效作用最好,毒效比达6.07。因此,在防治药剂中添加有机硅表面活性剂,可明显提高药剂对螺旋粉虱的防治效果,值得在生产上推广应用。The toxicity of 7 kinds of insecticides and the insecticides added silicone against spiraling whitefly were determined with potter spraying method,in order that analysis the synergistic effect of silicone on different insecticides.The results showed that the silicone had good synergistic effect.Spiraling whitefly had the most sensitivity to Lambda-cyhalothrin,followed by beta-cypermethrin and avermectins.Their LC50 value were 5.7405 mg/L,8.6831 mg/L and 16.8958 mg/L.After added silicone,their LC50 value was 0.9452,1.7138,13.2780 mg/L.The toxicity ratio were 6.07,5.07 and 1.27.As a result,added the silicone to insecticides could improve the effection of the insecticides against spiraling whitefly.
