The effect of watermelon mosaic vims ( WMV-2) to the host of melon, cotton aphid ( Aphid gossypii Glover) was studied by the screening of host, micro-measurement, dissection and cultivation in-house.

通过对棉蚜寄主选择、显微测量、解剖法及室内培养，研究了西瓜花叶病毒2号对棉蚜寄主甜瓜的趋向性、体长、胚胎数量、繁殖力等的影响。

Generally evaluated, cotton aphid had the highest fitness on Bt transgenic cotton, and the lowest fitness on Bt and CpTI transgenic cotton.

综合评价，棉蚜的生存和繁殖适合性在转单价基因抗虫棉上最高，在双价棉上最低。

, The transgenic cotton expressing two kinds of insect resistant genes varieties not only resist the cotton aphid, but also delay emerging of the resistance of the insect to the transforming Bt genes insect resistant cotton.

转双价基因抗虫棉既能抗蚜虫，又能减缓害虫对转Bt基因抗虫棉的抗性。

Biology identification: The weight of the cotton aphid were weighed, honeydew excretion of the cotton aphid were count. Honeydew excretion frequency of the cotton aphid were got. The different insect resistant cotton.

生物学鉴定：称量棉蚜成蚜的蚜重、计数棉蚜排蜜，得出棉蚜排蜜频率，获得不同抗性的品系。
