摘要
室内毒力测定结果显示，阿维菌素与苦参碱以有效含量的质量比1：24复配，对朱砂叶螨的毒力指数为苦参碱的47．45倍，共毒系数达155．84，具有明显的增效作用。田间小区试验表明，使用5％阿·苦水乳剂1000、2000、3000倍液防治朱砂叶螨，药后2～5d的防效均在93％以上，药后7d的防效在83％以上，持效期为7d。
The result of the test in laboratory showed that the co-toxicity coefficient of the mixture of abamectin and matrine （mass ratio 1：24） against Tetranychus cinnabarinus （Boisduval） is 155.84. Its toxicity is as 47.45 times as that of matrine and the synergism of the mixture is remarkable. In the field trial, the control effects of 1 000, 2 000 and 3 000 times of the 5 % mixture of abamectin and matrine EW to Tetranychus cinnabarinus are all over 93 % within 2-5 days and over 83 % on the 7th day after application, with the effectiveness maintained for 7 days.
