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Myzus persicae (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。

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.
