摘要
采用室内毒力测定法 ,就辣蓼、博落回、胡桃、烟草 4种植物提取物对菜蚜、蛞蝓两种蔬菜害虫的杀灭作用进行了试验。结果表明 ,辣蓼、烟草和博落回的乙醇粗提物以及辣蓼和博落回的水粗提物对菜蚜有很强的毒杀作用 ;辣蓼、博落回的醇提液对蛞蝓具有毒杀作用 ,水提液和醇提液均对蛞蝓有拒食和驱逐作用。
Indoor experiments on the killing effect of several crude extracts from plant such as Polygonum hydropiper , Madeaya cordate , Juglans regia and Nicotiana tabacum on vegetable aphids and slugs, were made.The results revealed that the ethanol extracts from Polygonum hydropiper ,Nicotiana tabacum and Madeaya cordate , and the water extracts from Polygonum hydropiper and Madeaya cordate were efficient in preventing and killing vegetable aphids. The ethanol extracts from Polygonum hydropiper and Madeaye cordate had killing effect on slug, extracts of water and ethanol had expel and antifood effect.
