This study was conducted to investigate the seasonal occurrence of aphids and to evaluate their efficacy in the field for the control of some aphids on soybean when Carbofuran, Disulfoton and Ortran were applied infurrow at the planting time in 1976. Foxglove aphid (Aulacorthum solani) and soybean aphid (Aphis glycines) were dominant species in the soybean field and there were two peaks in the year. The patterns of occurrence of aphids were different between in field and yellow-pan. Carbofuran and Disulfoton showed a good effects for the control of aphids but Ortran was less effective.
