摘　　要：联合毒力测定和室内毒效试验结果表明,高效氯氰菊酯和毒死蜱以百分含量3.5∶11.5的配比混合时共毒系数最大,增效作用最明显,毒效最高。按此比例混配而成的"15%高效氯氰菊酯·毒死蜱乳油"混剂(科绿),兑水1500倍和1000倍喷雾防治果期后期荔枝蒂蛀虫,喷施3次,隔7d喷1次,最后的防治效果分别为90.59%和93.73%,明显高于常规药剂4.5%高效氯氰菊酯乳油1500倍的防效。该混配剂对荔枝安全,杀虫谱广,能兼治荔枝蝽、尺蛾、毒蛾和卷叶蛾等多种荔枝害虫,是目前防治荔枝蒂蛀虫最好的药剂之一。The result of co-toxicity test and laboratory trial showed that the co-toxicity coefficient of alphacypermethrin and chlorpyrifos was highest against Conopomorpha sinensis when their mixture was 3.5：11.5, showing the highest synergism among all mixed ratio in the test. The field trial of the 15% alphaeypermethrin.chlorpyrifos EC （KeltiTM） which was mixed with 3.5% alphacypermethrin and 11.5% ehlorpyrifos against C. sinensis was conducted. The result showed that Compared to 4.5% beta-cypermethrin, Kelii was more effective to C. sirtensis and the control efficacy was 90.59% and 93.75% respectively after twice foliar spray, applied in 1 000 and 1 500 times volume of water per 7 days as a foliar spray. Being safe to lichi trees and fruits, having a broad spectrum and being effective to lichi stink bugs, loopworms, tussock moths and leaf rollers as well, Kelti had been regarded as one of the best pesticides that was used to control C. sinensis at present.
