摘要/Abstract

摘要： 分别用35种植物乙醇提取物处理的叶片饲养小菜蛾幼虫,研究非嗜食植物提取物对小菜蛾化蛹率和蛹重的影响。研究表明,茶枯(Camellia oleifera)、番石榴(Psidium guajava)、飞扬草(Euphorbia hirta)、南洋楹(Albizia falcataria)、薄荷(Mentha haplocalyx)、蓖麻(Ricinus communis)、假连翘(Duranta repens)的乙醇提取物对小菜蛾化蛹有显著的抑制作用(P<0.01,DMRT),化蛹率都低于30.00%;从蛹重来看,经积雪草(Centella asiatica)、芒果(Mangifera indica)、构树(Broussonetia papyrifera)、细叶桉(Eucalyptus tereticornis)的乙醇提取物处理,小菜蛾蛹重显著减轻(P<001,DMRT),蛹重(10只蛹)都低于0.0300g。

Abstract: After treated respectively with ethanol extracts (Etho Exts) of 35 kinds of non-host plants,leaves were used to feed Diamondback Moth (Plutella xylostella) and revealled the influence of plant extracts on the pupation rate and pupal weight.The results showed that the Etho Exts of Camellia oleifera,Psidium guajava,Euphorbia hirta,Albizia falcataria,Mentha haplocalyx,Ricinus communis,Duranta repens could significantly (P<0.01,DMRT) reduce pupation rate of P.xylostella,which were responsible for the lower pupation rates under 30%.The pupal weight of P.xylostella was significantly (P<0.01,DMRT) inhibited by the Etho Exts of Centella asiatica,Mangifera indica,Broussonetia papyrifera and Eucalyptus tereticornis,which resulted in ten pupal weight of P.xylostella was less than 0.0300g.
