摘要
[目的]从武夷山众多植物中筛选出一种高效杀虫植物。[方法]采用叶碟法,分别就博落回等多种植物对菜粉蝶幼虫的生物活性进行了测定。[结果]用1.00%的植物乙醇提取物处理过的叶碟饲喂菜粉蝶5龄幼虫后,根据其24和48 h的非选择性拒食率,发现博落回提取物对菜粉蝶5龄幼虫的生物活性最强。[结论]博落回植物是一种高效杀虫植物。
[ Objective ] The aim of the research was to select a new effective pesticide plant. [ Method ] Using leaf-disc method, the bioactivities of ethanol extract from the plants such as Macleya cordata against the 5^th instar larvae of Pieris rapae was determined resp. [ Result] The 5th instar larvae of Pieris rapae was treated with 1.00% ethanol extracts from the plants, The non-selective antifeedant rate of ethanol extract from the Macleya cordata against the 5^th instar larvae of Pieris rapae was most strong after 24 and 48 h rspe. [ Conclusion] The plant Macleya cordata was a new effective pesticide plant.
