摘　　要：为了筛选防治西花蓟马的高毒替代药剂，采用浸叶法测定了毒死蜱、丁硫克百威等7类15种药剂（原药）对西花蓟马的室内毒力。结果表明，94．8％阿维菌素、97．1％氟虫腈、95％毒死蜱、98．5％吡虫啉以及90．4％多杀菌素的致死中浓度（LC50）均低于10mg／L，作用效果较好，其中90．4％多杀菌素的作用效果最好，LC50为0．33mg／L。959，6氯噻啉、93．7％噻虫嗪、98．3％甲萘威以及92％丁硫克百威的LC50介于10～100mg／L，作用效果一般。97％啶虫脒、92．5％氟氟氰菊酯、96．5％高效氯氟氰菊酯、97％残杀威、97％高效氯氰菊酯以及97．9％联苯菊酯的LC50在100mg／L以上，作用效果较差，其中97．9％联苯菊酯的效果最差，LC50为486．1mg／L。从总体上看，生物源类药剂比其他种类药剂的作用效果好，而菊酯类药剂的作用效果相对最差。To screen new pesticides instead of high-toxic pesticides for control of western flower thrips, the toxicity of fifteen pesticides was determined by the leaf dipping method in the laborato- ry. The result indicated that 94.8 % abamectin, 97.1% fipronil, 95 % chlorpyrifos, 98.5 % imida- cloprid and 90.4% spinosad had good effects,with the LGs0 lower than 10 mg/L,in which 90.4% spinosad showed the best,with LG50 of 0.33 mg/L. The LGs0 of 95% imidaclothiz,93.7% thiame- thoxam,98.3% carharyl and 92% earbosulfan ranged from 10 mg/L to 100 mg/L. The effects of 97% aeetamiprid, 92.5%cyfluthrin, 96.5 % lambada-cyhalothrin, 97 % propoxur, 97 % beta-eypermethrin,and 97. 9% bifenthrin were worse,with LGso over 100 mg/L. 97.9% bifenthrin was least effective,with LG50 of 486.1 mg/L. Generally speaking, the bio-medicaments had the best effect and the pyrethroid pesticides relatively had the least effect.
