| 中文摘要:为阐明亚致死浓度吡虫啉对豌豆蚜Acyrthosiphon pisum产生的跨代效应，通过毒力测定确定吡虫啉对豌豆蚜的亚致死浓度，通过构建种群生命表系统解析豌豆蚜F0代和F1代暴露于亚致死浓度吡虫啉后对其F2代生长发育与繁殖的跨代影响。结果显示：0.1、0.5和1.0 mg/L浓度吡虫啉对豌豆蚜F0代的成虫存活率、单日产若蚜数以及各虫态发育历期均无显著影响；而当浓度≥2.0 mg/L时，则对这些指标产生显著的抑制或致死效应。1.0 mg/L浓度吡虫啉处理豌豆蚜F0代和F1代后，其F2代的成虫期缩短至12.41 d，繁殖期缩短至11.86 d，单雌总产仔量降低至30.60头，均显著低于对照；其F2代4龄若虫和成虫的最高存活率分别降至39.4%和58.2%，种群半数死亡时间提前至24~25 d，净增殖率、内禀增长率和周限增长率均较对照显著下降。表明豌豆蚜暴露于亚致死浓度吡虫啉（尤其是1.0 mg/L）后可对其F2代的生长发育、繁殖力及种群增长潜力有明显的跨代抑制作用。 |

| Abstract:To elucidate the transgenerational effects of sublethal imidacloprid concentrations on the pea aphid Acyrthosiphon pisum, toxicity bioassays were conducted to determine sublethal concentrations. A population life table approach was employed to systematically analyze the transgenerational impacts on growth, development, and reproduction in the F2 generation following exposure of the parental (F0) and first filial (F1) generations to sublethal imidacloprid. The results showed that imidacloprid concentrations of 0.1, 0.5, and 1.0 mg/L had no significant effects on adult survival, daily nymph production, or developmental duration of various instars in the F0 generation. However, concentrations ≥2.0 mg/L caused significant inhibitory or lethal effects on these parameters. After exposure of the F0 and F1 generations to 1.0 mg/L imidacloprid, the adult longevity, and reproductive period of the F2 generation were significantly reduced to 12.41 d, 11.86 d, respectively, and total fecundity per female decreased to 30.60 offspring, all of which were significantly lower than those of the control. In addition, the peak survival rates of the 4th-instar nymphs and adults in the F2 generation decreased to 39.4% and 58.2%, respectively. Furthermore, the median survival time of the population advanced to 24-25 d, and key population parameters, including the net reproductive rate, intrinsic rate of increase, and finite rate of increase, were all significantly lower than those of the control. These findings indicate that exposure of pea aphids to sublethal concentrations of imidacloprid, particularly at 1.0 mg/L, can exert significant transgenerational inhibitory effects on growth, development, fecundity, and population growth potential in the F2 generation. |
