摘　　要：以干扰作用控制指数(IIPC)为评价指标,测定了8个科9种植物茎叶乙醇抽提物对小菜蛾成虫的产卵驱避作用。结果表明,反枝苋(Amaranthus retroflexus L.)、茜草(Rubiaceae L_)、打碗花(Calystegia hedraceaWall.)、猪毛草(Scirpus wallichii Nees.)和粪箕笃(Stephania longa Lour.)对小菜蛾均有较好的驱避作用,处理24h后的驱避效果达80％以上;其对小菜蛾的驱避作用随施用后时间的延长而逐渐减弱。Repelling action of alcohol extracts from 9 species of plants against Plutella xylostella L. was evaluated by means of an interference index of population control (IIPC) .The results indicated that among them the alcohol extracted substances from 5 species of the plants, i.e. Amaranthus rptroflexus L., Rubia cordifolia L., Ca lystegia hederalea Wall. Stephania longa Lour., and Scipus wallichii Nees. revealed better results than those from other plants. The repelling rate were more than 80 % at 24 h after spaying of the alcohol extracts. The repelling effect gradually decreased after spaying of the alcohol extracts.
