摘要/Abstract

摘要： 基于植物与昆虫的协同进化理论,利用25科37种小菜蛾非嗜食植物的茎、叶、花或根的乙醇提取物,研究其对小菜蛾成虫的产卵驱避作用和对幼虫的拒食作用.结果表明,供试植物提取物对小菜蛾有不同程度的产卵驱避和拒食效果.羊蹄甲、细叶桉、飞扬草、假连翘、花椒、荷花玉兰、烟草的乙醇提取物对小菜蛾成虫产卵有较好的驱避效果,驱避率均达80%以上.一品红、构树、艾蒿、茶枯、垂柳、飞杨草、羊蹄甲、狗尾草的乙醇提取物对小菜蛾幼虫有较好的拒食作用,48h的拒食率达80%以上.

Abstract: Based on the theory of co-evolution between plants and phytophagous insects,the repellent and antifeedant effect of secondary metabolites of non-host plants on diamondback moth(DBM) Plutella xylostella was studied,aimed at finding out the oviposition repellents and antifeedants of insect pests.When the ethanol extracts(Etho Exts) of Bauhinia variegata,Eucalyptus tereticornis,Euphorbia hirta,Duranta repens,Zanthoxylum bungeanum,Magnolia grandiflora,and Nicotiana tabacum were applied respectively,the oviposition repellent rates were all over 80.00%;while after forty-eight hours treatment with the Etho Exts of Euphorbia pulcherrima,Broussonetia papyrifera,Artemisia argyi,Camellia oleifera,Salix babylonica,Euphorbia hirta,Bauhinia variegata,and Setaria viridisa,the antifeedant rates of DBM larvae were all more than 80.00%.
