摘　　要：研究了19℃、22℃、25℃、28℃和31℃恒温条件下,CMV烟草病株和健康烟草与烟蚜Myzuspersicae(Sulzer)生长发育和繁殖的关系。研究表明,随着温度的升高,在健康烟株(对照)和病株(处理)叶碟饲养条件下,烟蚜的成虫寿命和世代历期都显著缩短,繁殖力减弱。19℃时烟蚜的成虫寿命和世代历期最长,31℃时烟蚜最短。CMV烟草病株对烟蚜存活率和繁殖力有显著影响,与对照相比,烟草病株造成烟蚜成活率降低。烟蚜取食CMV烟草病株时,19℃烟蚜的繁殖力最强为36.9头,31℃最弱为2.17头。净增殖率R0在22℃时最大,在31℃时最小。周限增长率λ和内禀增长率rm在28℃和31℃时最大,在22℃时最小。世代平均周期T和种群加倍时间t在22℃时最大,在31℃时最小。研究结果说明,烟蚜的生长发育和繁殖与温度和感染CMV的烟草有关。Development And Reproduction of Myzus persicae （Sulzer） Feeding on Tobacco Infected Cucumber Mosaic Virus at Different Temperature Zhang Ling, Liu Yinghong, Ma lina, Duan Hang （Chongqing Key Laboratory of Entomology and Pest Control Engineering, Southwest University, Chongqing 400716） Abstract： The developmental duration and reproduction of Myzus persicae （Sulzer）that are reared on the tobacco infected cucumber mosaic virus （CMV） are researched under the different temperature . There are five temperature which contains 19℃ ,22℃ ,25℃ ,28℃ and 31℃ .When increase the temperature , the adult longevity and generation duration increased , the fecundity weakened . Under the five temperature , its adult longevity and generation duration were the longest at 19℃ and the shortest at 31℃. When feeding on the tobacco infected cucumber mosaic virus , its fecundity was the highest at 19℃ and the lowest at 31℃. Based on the parameters of the life table ,of the 5 temperature studied , the temperature at 22℃ is considered to be the most suitable for M. persicae （Sulzer）.It was suggested that the development and reproduction of Myzus . （Sulzer） might be related to the temperature and tobacco infected cucumber mosaic virus.
