摘要
试验结果表明:除从油菜上转到桃树上不成功外,烟蚜可在烟草、油菜和桃树之间成功转换,且同寄主之间的转换比异寄主之间的转换生殖前期短,产仔量大。烟蚜寄主转换以rm值的大小依次为桃树转油菜>烟草转油菜>油菜转烟草>桃树转烟草>
An experiment was carried out to study the effects of host alteration on population characteristics of Myzus persicae. The results showed that, except the alteration from rape to peach, the aphid could be successfully altered among tobacco, rape and peach. The pre reproductive time was shorter and reproduction was higher in the alteration within the same host than those in the alteration among different hosts. The intrinsic rates of natural increase r m of the aphid population in various host alterations were in the following order: peach to rape>tobacco to rape>rape to tobacco>peach to tobacco>tobacco to peach.
