摘要：目的对10味常用杀虫中药的杀虫效果进行筛选,为研制新的植物源农药奠定基础。方法以中药提取物对3种害虫的校正死亡率为观察指标,分别采用载玻片浸渍法、微量点滴法、虫体浸渍法测定10种常用杀虫中药的水提物及醇提物对朱砂叶螨、甘蓝蚜、黏虫的触杀作用。结果中药醇提物对3种害虫均有触杀作用,水提物无明显效果。其中,百部醇提物对3种害虫均有明显的触杀作用,校正死亡率分别为78.7%、85.9%、96.7%;苦皮藤、苦参、苍耳子、甘遂乙提物对朱砂叶螨有较好的触杀作用,将苦皮藤、百部、苦参、苍耳子、甘遂按体积比2∶1∶1.5∶1.5∶1.5∶1.5配伍时,对朱砂叶螨杀虫活性较单味药提取物增强,校正死亡率为96.5%。瑞香狼毒、藜芦、苍耳子、白芥子醇提物对甘蓝蚜有较强的杀灭作用,将苍耳子、百部、瑞香狼毒、藜芦按体积比1∶1.5∶2∶2配伍时,其对甘蓝蚜的活性增强,校正死亡率为93.1%。结论中药提取物经配伍后,其杀虫活性增强。
Objective To lay the foundation of new botanical pesticides by screening the insecticidal efficacy of 10 commonly used TCM pesticides.Methods Slide immersion method, trace intravenous drip method and insect body dipping method were respectively used to measure contact action of water extract and ethanol extract of the 10 commonly used TCM pesticides toTeranychus cinnbarinus,Brevicoryne brassicaeandMythimna separate, with herbal extracts to three kinds of insect pests of corrected mortality as observation indexes,Results Alcohol extracts for three kinds of insect pests were found to have contact action, and water extracts had no obvious effect. The Stemonae Radix alcohol extract had obvious contact action on three kinds of insect pests, and corrected mortality rates were 78.7%, 85.9%, and 96.7%, respectively; ethanol extracts of Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix showed good contact action to Teranychus cinnbarinus,. The volume ratio of compatibility among Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix was 2:1:1.5:1.5:1.5:1.5. The insecticidal activity to Teranychus cinnbarinus, was stronger than extracts of single herbs, and corrected mortality was 96.5%. Alcohol extracts of Stellera, hellebore, white mustard seed, and Xanthii Fructus showed good contact action toBrevicoryne brassicae. When the volume ratio of compatibility among Xanthii Fructus, Stemonae Radix, Stellera, and hellebore was 1:1.5:2:2, the activity toBrevicoryne brassicae increased. and corrected mortality was 93.1%.Conclusion The insecticidal activity will be enhanced after TCM extracts are under compatibility.
