将4种寄主植物上的4种不同体色的桃蚜分别接到该4种寄主植物上进行反复试验，结果表明：不同体色生物型桃蚜在各寄主植物上的存活率，成、若蚜发育历期，产仔动态及内禀增长力均有明显差异，说明不同体色生物型对不同寄主植物的适应性不同。尤其是各色型个体当从烟草转接到桃树、从油菜转接到桃树或烟草、从甘蓝转接到桃树或烟草时，新接蚜虫均不能存活。
The four kinds of host plants on the four different body color of Myzus persicae were received on the four kinds of host plants for repeated tests, the results showed that: the different body color Myzus persicae in each host plant survival rate, as, if The developmental stages of the aphids, litter size and intrinsic growth potential were significantly different, indicating that different body color of different host plant adaptability different. In particular, individuals of all sexes can not survive a new call of aphids when transferring from tobacco to peach, from rape to peach or tobacco, and from cabbage to peach or tobacco.
