摘　　要：报道了万寿菊（ＴａｇｅｔｅｓｅｒｅｃｔａＬ．）粗提物和α－三聚噻吩对小菜蛾Ｐｌｕｔｅｌａｘｙｌｏｓｔｅｌａ（Ｌ．）成虫产卵忌避作用的生测结果，万寿菊根甲醇索氏提取物对小菜蛾成虫产卵有强烈忌避作用。在室内，根甲醇索氏提取物（１００００ｍｇ／ｌ）的非选择性产卵忌避率为９７３３％；室外盆栽试验结果表明，万寿菊根甲醇索氏提取物浓度为２０００ｍｇ／ｌ，对小菜蛾成虫的产卵忌避率为５６４８％。The crude extracts from marigold had the detertory effect against the viposition of diamondback moth.In the choice test,the deterrent rate is 97.33%.In the no-choice test,the deterrent rate is 93.33%.The further study confirmed the oviposition deterrent.The whole plant sprayed by the crude extracts have been shown the same effect against the oviposition deterrent.In the choice test,the deterrent rat is 90.35%.In the no-choice test,the deterrent rate is 80.35%.In the field model test,the deterrent rate is over 50% .
