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.
