Changes of trehalase activity of soybean aphids in the same generation under imidacloprid and thiamethoxam stresses.

Note: Different lowercase letters indicate that trehalase activity of soybean aphids in the same generation under imidacloprid and thiamethoxam stress is significantly different (P < 0.05). F1, F2, F3, F4, F5 = The first, second, third, fourth, and fifth generation of the fourth instar nymphs. LC50-IMI represents the fourth instar nymphs treated with LC50 imidacloprid; LC50-THI represents the fourth instar nymphs treated with LC50 thiamethoxam; LC30-IMI represents the fourth instar nymphs treated with LC30 imidacloprid; LC30-THI represents the fourth instar nymphs treated with LC30 thiamethoxam.
