| 摘要: |
| 从烟草和油菜上采回各自的红色型、绿色型、黄绿色型、褐色型 4种体色生物型 ,再分别接到烟草、油菜和萝卜上 ,连续 1～ 4代观察记载其体色生物型的稳定性。结果表明 ,桃蚜体色生物型的稳定性随寄主不同存在显著差异 ,不同代别其稳定性也有一定的差异 ,在不同体色生物型中 ,以黄绿色生物型最为稳定。 |

| Abstract: |
| This paper deals with the influence of host plants on stability of body-colour biotypes of the aphid,Myzus persicae (Sulzer).The individuls of red-type,green-type,yellow-type and brown-type of the green peach aphid were collected from tobacco (Nicotiana tabacum L.),rape (Brassica compestris L.) respectively and bred successively 1-4 generations on tobacco,rape and radish (Raphanus sativus L.) under indoor conditions.Results showed that the stability of various body colour types were of significant difference as the hosts and the generations changed.The yellow-green biotype showed the most stability among the 4 body-colour biotypes. |
