摘　　要：采用室内浸渍法，将三唑磷与甲氰菊酯、三唑磷与三氟氯氰菊酯各以５种不同比例混配，对棉蚜进行了增效作用研究。经测定，三唑磷与甲氰菊酯以５∶５，７∶３，９∶１混配，共毒系数分别为４５１．８１，３１２．３和２１７．４；三唑磷与三氟氯氰菊酯以７∶３，９∶１，２０∶１混配，共毒系数分别为１２０．７，１７７．７，１３８．８。此结果表明，这几种药剂以适当比例混配对棉蚜具有增效作用，为加工生产混剂和使用提供必要的理论根据。The present paper tested the synergism of phentriazophos combined respectively with fenpropathrin and cyhalothrin to the cotton aphids by using immersion. The results showed that phentriazophos combined with fenpropathrin in 5: 5, 7: 3, 9: 1 had significant syniergictic action, the cotoxicity coefficients were 451.8, 312, 217.4 respectively, when combined with cyhalothrin in 7: 3, 9: 1, 20: 1, the cotoxicity coefficients were 120.7, 177.7, 138.8 respectively. It was suggested that these two different kinds of insecticides combination was an useful method for controlling resistant cdtton aphids.
