【摘要】 试验初步测定了11种非寄主植物乙醇提取物对黄曲条跳甲(Phyllotrata triolata)的产卵驱避作用。结果表明,11种非寄主植物乙醇提取物对黄曲条跳甲成虫产卵均有一定的驱避作用,其中尾叶桉、夹竹桃、牵牛花、巴西菊等的乙醇提取物驱避效果最好;蟛蜞菊、木薯、马尾松、水葫芦等的乙醇提取物效果次之;地桃花乙醇提取物效果较差。更多还原

【Abstract】 Effects of eleven kinds of Secondary metabolism substance as oviposition deterrent against Phyllotreta strio-lata Fab.were preliminary tested.Results showed that all extracts could affect oviposition of P.striolata in some degree . These plants, Urena lobata , Eupatorium odoratum , Myoporum bontioides , can’ t keep good oviposition deterring rate, but Eucalyptus urophlla, Nerium indicum, Ipomoea hederacea were significant. It is suggested that Praxelis clematidea is most hopeful to be developed as biorational botanical pesticides in eleven kinds of tested plants.更多还原
