| 中文摘要:为评价吡虫啉对日本通草蛉Chrysoperla nipponensis（Okamoto）实验种群的亚致死效应，采用浸渍法处理日本通草蛉卵，测定了吡虫啉亚致死剂量LC10、LC20、LC30对日本通草蛉生长发育、繁殖力和生命表参数的影响。结果表明，经吡虫啉亚致死剂量LC10、LC20、LC30处理后，日本通草蛉幼虫发育历期和蛹期分别延长0.86~2.04 d和1.00~2.37 d，平均单头蛹重降低1.16~1.56 mg，羽化率降低6.13%~13.08%；雌虫产卵前期延长0.19~0.51 d，每雌平均产卵量减少17.75~51.64粒，寿命减少1.75~2.84 d；内禀增长力（rm）、净繁殖率（R0）和周限增长率（λ）均显著降低，平均世代历期（T）和种群加倍时间（Dt）均显著延长。研究表明，吡虫啉亚致死剂量对日本通草蛉种群的增长具有抑制作用。 |

| Abstract:To study the sublethal effects of imidacloprid on the experimental population of Chrysoperla nipponensis (Okamoto), the eggs of C. nipponensis were treated with LC10, LC20, and LC30 of imidacloprid by dipping method and the lacewing's development, fertility, and life-table were tested. 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. |
