寄生通常会通过改变宿主的发育方向而导致脂质和脂肪酸发生相当大的变化。本研究记录了棉蚜被寄生后体重和游离脂肪酸含量的变化。结果表明，与未寄生的蚜虫相比，被寄生的棉蚜重量有所增加，且在被Lysiphlebia japonica寄生后，在1、2、3龄时体重显着增加。游离脂肪酸检测试剂盒和GC-MS显示，脂肪酸含量在寄生初期增加，但在寄生3天后下降。 7个与脂肪酸合成途径相关的基因在寄生的蚜虫中显着上调，表达量增加了1.96-10.97倍。我们的数据描述了寄生的棉蝇脂肪酸含量发生的变化。
Parasitism usually causes considerable changes in lipids and fatty acids by redirecting the development of the host. In this study, changes in weight and in free fatty acid content of cotton aphids were recorded after aphids had been parasitized. Results showed that the weight of parasitized Aphis gossypii was increased compared to nonparasitized aphids, and significantly increased weights were detected at 1, 2, and 3 instars after parasitization by Lysiphlebia japonica. Free fatty acid test kits and GC-MS showed that the fatty acid content increased in the early stage of parasitization but decreased after 3 days of parasitization. Seven genes related to the fatty acid synthesis pathway were significantly upregulated in the parasitized aphids, where they were 1.96-10.97 times greater. Our data described the change that occurs in the fatty acid content of parasitized A. gossypii.
