Description
Summary:The soybean aphid Matsumura (Hemiptera: Aphididae) is a major pest of soybean and poses a serious threat to soybean production. Studies on the effect of acetamiprid on the life table parameters of , provide important information for the effective management of this pest. We found that exposure to acetamiprid at LC significantly extended the mean generation time, adult pre-reproductive period, and total pre-reproduction period compared with the control, whereas exposure to acetamiprid at LC significantly shortened these periods. Exposure to acetamiprid at both LC and LC significantly decreased the fecundity of the female adult, net reproductive rate, intrinsic rate of increase, and finite rate of increase compared with the control. The probability of attaining the adult stage was 0.51, 0.38, and 0.86 for a newly born nymph from the LC acetamiprid treatment group, LC acetamiprid treatment group, and control group, respectively. Acetamiprid at both LC and LC exerted stress effects on , with the LC treatment significantly decreased the growth rate compared with the LC treatment. The present study provides reference data that could facilitate the exploration of the effects of acetamiprid on in the field.
