Abstract

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.
