摘要: 中华卵索线虫Ovomermis sinensis感染棉铃虫Helicoverpa armigera 1天后,棉铃虫幼虫血淋巴中游离氨基酸总量大幅度下降,各种游离氨基酸的含量也是如此变化。感染2~4天后的棉铃虫血淋巴中游离氨基酸总量变化不大,各种游离氨基酸的含量有升有降。感染5~6天后的棉铃虫血淋巴中游离氨基酸总量和各种氨基酸的含量都急剧上升。研究表明,中华卵索线虫寄生棉铃虫时,棉铃虫血淋巴中游离氨基酸含量的变化朝着有利于线虫生长发育的方向进行。

Abstract: Compared with the control experiment,in one day after Helicoverpa armigera was infected by Ovomermis sinensis, the total of free amino acids in the haemolymph of H. armigera decreased greatly. In 2-4 days after the infection, the total of free amino acids in the haemolymph of H. armigera infected by O. sinensis did not change much: some free amino acids increased, and the others decreased. In 5-6 days after the infection, the total of free amino acids and all kinds of free amino acids in the haemolymph of H. armigera infected by O. sinensis during increased rapidly. The results showed that the contents of free amino acids in the haemolymph of H. armigera infected by O. sinensis changed towards benefiting the growth of O. sinensis.
