The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.
