| Abstract: | To confirm control efficacy of imidacloprid by seed dressing on Sitobion avenae and effect on its natural enemies, experiment was conducted with tested materials of pesticide, imidecloprid and wheat, Jingdong 8 in field. Results showed that wheat aphid totals were 4 204, 4 218, 9 911 per hundred plants, respectively, with treatment A （ seed dressing quality of 1.2 g · kg^-1 ）, treatment B （ seed dressing quality of 0.8 g · kg^-1） and ck in the whole wheat growth period, and was of significant difference （P 〈 0.05 ） between treatment A, treatment B and ck. Control effect against aphids was achieved with treatment A and treatment B, furthermore, 82.13% and 78.11% of control effect were arrived on May 17th. Wheat yields with treatment A, treatment B and ck were O. 701 3,0.598 8,0. 564 4 kg ~ m -2, respectively, and significant difference（ P 〈 0.05 ） between treatment A, treatment B and ck. Total amounts of parasitic aphids and ladybird, were significantly different （P 〈 0.05） between treatment A, treatment B and ck. |
