The results showed that larval duration and pupal duration of C. nipponensis were prolonged by 0.86-2.04 d and 1.00-2.37 d after treated with imidacloprid, respectively. The average pupal weight and emergence rate decreased by 1.16-1.56 mg and 6.13%-13.08%, respectively. The pre-oviposition of C. nipponensis was prolonged by 0.19-0.51 d and the fecundity reduced by 17.75-51.64 eggs per female. The average longevity of female adults was shortened by 1.75-2.84 d. The intrinsic rate of increase (rm), net reproductive rate (R0), and finite rate of increase (λ) were all decreased significantly compared to the control. However, the mean generation time (T) and the population doubling time (Dt) were both prolonged significantly. The results indicated that the sublethal dosage of imidacloprid could decrease the development rate of laboratory populations of C. nipponensis. %K 日本通草蛉 亚致死效应 吡虫啉 生命表< %K br> %K Chrysoperla nipponensis sublethal effect imidacloprid life-table %U http://www.zwbhxb.cn/ch/reader/view_abstract.aspx?file_no=20160619&flag=1
