摘　　要：开展了0.5%印楝素乳油、1%苦皮藤素乳油防治茶卷叶蛾室内药效试验。0.5%印楝素乳油800倍液和1%苦皮藤素乳油液750倍防治茶卷叶蛾效果良好,药后1、3、5 d防治效果分别为70.00%、85.19%、100%和66.67%、88.89%、95.83%,速效性也较好。初步试验结果表明,0.5%印楝素乳油、1%苦皮藤素乳油适用于茶园防治茶卷叶蛾幼虫。Effects of 0.5% azadirachtin EC and 1%Celangulins EC against the larva of Homona coffearia Meyrick were performed in laboratory. Both 2 botanic Pesticides exhibited the high control efficiency against Homona coffearia Meyrick with fast availability in laboratory, and the mortality of Homona coffearia Meyrick were 70%, 85.19% and 100%, and 66.7%、88.89% and 96.67% after treatment with dilutions of 800 times（0.5% azadirachtin EC）and 750 times（1%Celangulins EC）for 1, 3 and 5 days, respectively. The preliminary results suggested that 0.5% azadirachtin EC and 1% Celangulins EC were both suitable for the controlling of Homona coffearia Meyrick in tea plantation.
