2、病毒体浓度的增加而提高外,还与烟粉虱的龄期及性别有关。双生病毒除了在植物与粉虱之间直接传播外,还可通过烟粉虱交配及经卵携带的途径在烟粉虱个体和代别间进行传播。寄主植物、双生病毒的一些特殊蛋白以及烟粉虱内共生菌产生的GroEL蛋白,都可影响烟粉虱携带的双生病毒种类及传毒的可能性。双生病毒可对烟粉虱的发育、存活和生殖产生不利或有利的影响。雌成虫携带番茄黄化曲叶病毒(tomatoyellowleafcurlvirus,TYLCV)后,存活力和生殖力均下降;而携带番茄斑驳病毒(tomatomottlevirus,ToMoV)后,生殖力提高。
3、此外,植物感染双生病毒后,其对烟粉虱的适合性可能提高。关键词:烟粉虱;双生病毒;病毒传播;番茄黄化曲叶病毒;番茄斑驳病毒中图分类号:Q968文献标识码:A文章编号:04546296(2006)03051308Transmissionofgeminivirusesbywhitefly121*JIUMin,ZHOUXuePing,LIUShuSheng(1InstituteofInsectSciences,ZhejiangUniversity,Hangzhou310029,China;2InstituteofBiotech
