| 摘 要： | 在以作用因子组建的生命表和干扰作用控制指数(IIPC)的基础上建立植物保护剂的研究方法和综合评价指标,以表示驱避成虫选择寄主,干扰成虫的产卵行为,对卵孵化的影响,以及干扰幼虫的行为,包括逃避、拒食、幼虫特别是初孵幼虫中毒死亡的作用.采用所建立的研究方法和评价指标的试验结果表明,菜田附近大多数非寄主植物的乙醇抽提物(干重1g·100ml-1)如大叶桉(Eucalytusrubusta)、蟛蜞菊(Wedeliachinensis)等对保护十字花科蔬菜免受小菜蛾为害起着明显的作用.印楝油对小菜蛾幼虫的防治效果相当显著.机油乳剂(CALTEX产品)对桔全爪螨具有明显的控制效果

| Abstract: | An interference index of population control (IIPC) was constructed for investigating the complex effects of plant protectants,including the effects of repelling insect pests away from the plant,deterring the egg laying of adults and the continuation of feeding, and causing death by toxicity. At the same time, indicated by IIPC, the alcohol extracts of some common plants, such as Eucalytus rubusta, Wedelia chinensis etc. and the neem oil gave very good results to protect the plant against Plutella xylostella . The D C Tron NR Petroleum Spray Oil (CALTEX) also gave an excellent effect to protect citrus against red mite. All the experiments show the important role of the repellent effect on the pests. |
