【摘要】 本文报道南蛇藤属４种植物——苦皮藤（Ｃｅｌａｓｔｒｕｓａｎｇｕｌａｔｕｓ）、穗花南蛇藤（Ｃ．ｖａｎｉｏｔｉ）、大芽南蛇藤（Ｃ．ｇｅｍｍａｔｕｓ）和显柱南蛇藤（Ｃ．ｓｔｙｌｏｓｕｓ）的根皮乙醇提取物对二斑波缘龟甲（Ｂａｓｉｐｒｉｏｎｏｔａｂｉｓｉｇｎｓａｔａ）、菜青虫（Ｐｉｅｒｉｓｒａｐａｅ）和家蚕（Ｂｏｍｂｙｘｍｏｒｉ）幼虫拒食作用的测定结果表明，４种植物的根皮乙醇提取物均表现出显著的拒食作用，比较４种植物的拒食活性差异，其活性大小为：苦皮藤、穗花南蛇藤＞大芽南蛇藤＞显柱南蛇藤，说明在南蛇藤属植物中除了苦皮藤外，穗花南蛇藤、大芽南蛇藤和显柱南蛇藤也是具拒食作用的杀虫植物资源。更多还原

【Abstract】 The antifeeding effects of the ethanol extracts from root barks of Celastrus plants were evaluated in laboratory on some insects by bioassay.The results showed that the ethanol extracts from root barks of C.angulatus,C.vaniotii,C.Stylosus and C.gemmatus had remerkable antifeeding effects on the larvae of Basiprionota bisignsata,Pieris rapae and Bombyx mori. The differences of the antifeeding effects among the four kinds of plants were contrasted in the paper.It indicated that the C.vaniotii,C.stylosus and C.gemmatus may be taken as potential insecticides as antifeedants besides the C.angulatus.更多还原
