| 摘 要： | 本文对10个科I1种植物的茎叶进行抽提，测定抽提物对菜粉蝶成虫的产卵驱避作用，杀卵作用以及杀低龄幼虫的作用,并应用干扰作用控制指数(IIPC)作为评价指标米评价植物抽提物的作用效果。试验结果表I刿，苍耳Xantgium sibiricum Patrin与红宝巾Bougainvillea glabra Choisy对成虫的产卵驱避作用明显，其干扰作用控制指数分别为0．127、0．192，即防治效果分别达到87．3％、80．8％。 |

| Abstract: | Based on the theory of co-evolution between plants and insects, many plants release secondary metabolites to protect them from being infected by insect pests. 11 plants were used in the paper to determine the effect of repelling the pest,Pieris rapae L,away from the plants, deterring the egg laying of adult, and causing death by toxicity. An interference index of population control (IIPC) was constructed to evaluate the effect of plant extracts. The result showed that 2 plants extracts, Xantgium sibiricum Patrin and Bougainvillea glabra Choisy,had good effect against the pest Pieris rapae L. and the IIPC were 0.127,0.192 respectively,that is,the control efficacy were 87.3%,80.8% respectively. |
