摘　　要： 在室内测试了19种植物乙醇提取物对青花菜上桃蚜的影响，结果表明：处理后1-2 d，辣椒、勒杜鹃、蓖麻等7种植物的乙醇提取物对桃蚜具有较好的忌避作用；辣椒、勒杜鹃等9种植物的乙醇提取物，桃蚜存活指数较低；马齿苋、蓖麻等9种植物的乙醇提取物，桃蚜繁殖忌避指数较小；处理后实验桃蚜种群干扰作用指数IIPC〈1的植物有17种；单独使用勒杜鹃、辣椒、马齿苋、蓖麻对桃蚜的自然种群都有一定的控制作用；勒杜鹃与马齿苋、辣椒与马齿苋混用、马齿苋与蓖麻混用的组合对桃蚜的自然种群控制效果比较好。 The effects of 19 kinds of plant ethanol extracts against Myzus persicae of broccol were studied. The results showed that 7 kinds of plant ethanol extracts from Capsicum frutescens, Bougain- villea glabra ,Ricinus communis ect. had relatively better deterrent effects on Myzus persicae of broccoli after 1-2d treatment. The Myzus persicae had lower survival index once treated by 9 kinds of plant ethanol extracts from Capsicum frutescens ,Bougainvillea glabra ect.. Myzus persicae had less reproduction deterrence index after treated by 9 kinds of plant ethanol extracts from Portulaca oleracea ,Ricinus communis ect.. The interference index of population control （IIPC） of 17 kinds of plant ethanol extracts on the laboratory populations Myzus persicae of Broccoli were 〈1. In field, the extracts from Bougainvillea glabra ,Capsicum frutescens , Portulaca oleracea and Ricinus communis had some controlled efficts on population,while the mixtures of Bougainvillea glabra and Portulaca oleracea ,Capsicum f rutescens and Portulaca oleracea as well as Portulaca oleracea and Ricinus communis had reasonably better controlled efficiency.
