Abstract
The field control effect of eleven insecticides was studied aimed to screen the insecticides with high control effect to Aphis gossypii(Glover).The results indicated that 40% Profenofos EC,5.8% Fipronil SC,20% Acetamiprid WP had good control effect to Aphis gossypii(Glover),which control effects were more than 86% after 1 day,whereas 25% Diafenthiuron EC,5% Fenpyroximate SC,240g/L Spirotetramat SC,50% Pymetrozine WG and 5.8% Fipronil SC had good persistent effect,and their control effects after 7 days were significantly better than other treatments.40% Profenofos EC,5.8% Fipronil SC and 20% Acetamiprid WP with a reasonable use of the other four insecticides,which had good persistent effect to Aphis gossypii(Glover),could effectively control Aphis gossypii(Glover).
