摘　　要：[目的]筛选冬季清园时防治菱纹叶蝉有效药剂。[方法]通过室内毒力测定试验和田间防效试验研究了印楝素等5种植物源杀虫剂对菱纹叶蝉的防治效果。[结果]冬季清园使用0.5%藜芦碱可溶性液剂防治菱纹叶蝉,持效期长,可维持10~14 d,使用0.3%印楝素乳油持效期为7 d,菱纹叶蝉对它们十分敏感,是防治菱纹叶蝉比较理想的药剂,适宜推广;生产上推荐使用0.5%藜芦碱可溶性液剂1 000倍稀释液和0.3%印楝素乳油600倍稀释液冬春伐时防治菱纹叶蝉,可有效降低越冬基数。采用1.1%百部·楝·烟乳油防治桑树上菱纹叶蝉,不仅使用量低,而且残效消解快,无残留,不污染环境,建议在第1代菱纹叶蝉发生期使用1.1%百部·楝·烟乳油1 200倍稀释液。[结论]试验结果为菱纹叶蝉的有效防治提供了理论依据。[ Objective] The aim was to screen out effective drugs to control Hishirnones sellatus Uhler. [ Method] W e studied indoor virulence and field efficacy of several botanical insecticides against Hishirnones sellatus Uhler. [ Result] The 0. 5% veratrine solubility agent was used to control Hishhnones sellatus Uhler in garden in winter,and had long persistent period of 10 - 14 days,meanwhile the persistent periodin EC was 7 da.ys＇,Hishirnones sellatus Uhler was very sensitive to t h e m, so they were ideal drugs and suitable for generalization. In the production,1 000-time dilution of 0. 5% veratrine solubility agent and 600-time dilution of 0. 3% azadirachtin EC were used Uhler in winter and spring and could decrease the over-wintered number of Hishirnones sellatus Uhler. The Llilang No. 2 was mones sellatus Uhler on mulberry, not only needed less dosage, but also had no residue and n1 200-time dilution of Llilang No. 2 was used to control Hishirnones sellatus Uhler at the occurrence perioresults provide theoretical basis for the control of H i sh im o n s sellatus Uhler.
