【摘要】 本文应用干扰作用控制指数(IIPC)评价了30种植物乙醇提取物对小菜蛾实验种群的干扰作用,结果表明:在供试的30种植物乙醇提取物中,含羞草、飞机草、香茅草和鼬瓣花乙醇提取物对小菜蛾种群的干扰效果是明显,其IIPC值低于0.1之下,即这些提取物对十字花科蔬菜的保护效果达到90％以上,可作为组建十字花科蔬菜植物保护剂的成分。更多还原

【Abstract】 In the paper, the interference indices of population control (IIPC) were used to evaluate the effects of spraying alcohol extracts of the non - preferable plants on the experimental population of DBM Plutella xylostella L.. The results showed that the alcohol extracts of Mimosa pudica L., Eupatorium odoratum L. , Cymbopogon citratus Stapf and Galeopsis bifida Boenn. gave noticeable effect to protect the plant against Plutella xylostella. L.. The IIPC of these extracts are below 0.1, it means that the effects of these extracts were over 90% . These extracts maybe used as repellents to construct the cruciferous plant protectant.更多还原
