| 摘 要： | 系统研究棉蚜在不同寄主植物间地其种群特征的影响。通过Ｗeibull函数模拟，生命表分析和高氏距离分析比较得出，棉蚜从冬寄主向夏寄主转换移时，木槿与石榴、石榴与花椒间表现有明显分离。４种夏寄主间相互转换时也有一定组合间有显著差异，但当经若干代生长、繁殖后４ 的种夏寄主上种群作比较时，其差异性均没有达到明显分离的程度。

| Abstract: | The host alterations of Aphis gossypii among different winter and summer host plants compared with the population characters were studied By the analyses of Weibull functions,life table and Gower distance,the populations on different summer host plants transplanted from three winter hosts presented that there were significant differences between Rose of Sharon and Pomegranate or Pomegranate and Chinese prickly ash As the transplantation among four summer hosts,there were significant differences between some combinations However,there were no obvious differentiation after the population had bred several generations on four summer hosts |
