| Abstract: | In field the control effect of different dosage of imidacloprid on wheat aphids was evaluated in 2001. The results showed that the economic effective dosage of imidacloprid against mixed wheat aphids Macrosiphum avenae (Fabricius) and Rhopalosiphum padi (Linnaeus)] was 15～30 ga.i./ha.The effect on yield of wheat was related to control effect, survivals, treatment perid. |
