摘要: 目的:了解河北地区杀虫植物资源概况,寻找和开发本省植物性杀(抑)虫剂。方法:丙酮和植物干粉按6∶1的比例浸泡提取,提取液以水稀释30倍和100倍浸渍处理淡色库蚊Ⅲ~Ⅳ龄幼虫。结果:以30倍稀释液处理,造成蚊幼虫死亡率达50%以上的植物有44种;以100倍液浸渍,造成蚊幼虫死亡率95%以上的植物共7种,其中茵陈蒿、薄荷提取液的死亡率达100%;试验中发现一些植物提取液对蚊幼虫具有生长发育的抑制作用。结论:杀虫植物所含成分对不同昆虫生物活性的敏感性不同,蒺藜、茵陈蒿、薄荷、佩兰、曼佗罗、葎律草等植物,在防制蚊虫方面具有进一步开发利用的价值。

Abstract: species of plants were collected mainly in Hebei province for selection of botanical insecticides. These plants were air-dried and ground, then extracted by acetone in a ratio of acetone/plant powder=6/1. In the tests of soaking 3-4 instar larvae of Culex pipiens pallens with 30-fold diluents of the plant extractions, 44 species of plants caused at least 50% mortality of the larvae. Treated with 100-fold diluents, 7 plants extractions caused more than 95% mortality of the larvae, and 2 of those,Memtha haplocalyx and Artemisia capillaris caused 100% mortality. In conclusion, some plants, such as Tribulus terresteis, Memtha haplocalyx, Artemisia capillaris, Eupatorium fortunei, Datura stramouium and Humulus scamdens, have value of development.
