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.

Key words: Ovomermis sinensis, Helicoverpa armigera, haemolymph, free amino acids, content
