摘要： 为了科学有效地防治丹参旋心异跗莹叶甲，从而进行了农药药剂筛选试验。结果表明：所选的9种农药在室内毒力测试中，对旋心异跗莹叶甲成虫均具有一定的毒力作用，但相互间存在较大的差异，其中2种微生物农药绿僵菌和阿维菌素的效果较差；化学农药中硫丹的效果最好，其试验用最大浓度的校正死亡率达到97.08%；其次，效果较好的为吡虫啉和高效氯氟氰菊酯；3种植物源农药效果均较好，1%苦参碱SL、0.5%黎芦碱SL、0.3%印楝素EC最大试验浓度的校正死亡率分别为97.08%、96.35%、77.37%。在田间防效试验中1%苦参碱SL、0.5%黎芦碱SL的防效较好，施药后7天的防效分别达到了97.04%、98.25%；而25%硫丹EC、2.5%高效氯氟氰菊酯ME施药后7天的防效分别为84.17%、71.33%。可见，2种生物农药1%苦参碱SL和0.5%黎芦碱SL的防效优于其他测试农药，值得在生产实践中推广应用。

Abstract: The pesticide screening tests were done to order to control Apophylia flavovirens Fairmaire. effectively in salvia fields. The results showed that, all of 9 pesticides have certain toxicity to Apophylia flavovirens Fairmaire. adults, but there was a great difference between each other. In laboratory the control effects of 2 kinds of microbial pesticides including Metarhizium and Avermectin were worse than other pesticides. The control effects of Benzoepin was the best in 4 kinds of chemical pesticide, which the adult corrected mortality made by was up to 97.08 % with the maximum concentration in tests; them of Imidacloprid and Lambda-cyhalothrin were better than Thiamethoxam. The control effects of 3 kinds of botanical pesticides including 1% Matrine SL, 0.5% Veratridine SL and 0.3% Azadirachtin EC were also better than other pesticides, whose corrected mortality treated with the maximum concentration were 97.08%, 96.35% and 77.37% respectively. In field experiment, the control effects of 1% Matrine SL and 0.5% Veratridine SL were better than other pesticides, that 7 days after treatment the control effects of them were 97.04% and 98.25% respectively. And which of 25% Endosulfan EC, 2.5% Lambda-cyhalothrin ME were just 84.17% and 71.33% respectively. Therefore, the control effects of 1% Matrine SL, 0.5% Veratridine SL were better than the other tested ones, which were worthy of application in practice for controlling Apophylia flavovirens Fairmaire..
