禾谷缢管蚜Rhopalosiphum padi（L.）麦蚜是一种世界性的小麦害虫。高效氯氰菊酯广泛用于防治刺吸式害虫，包括刺吸式红蜘蛛。帕迪。随着时间的推移，田间施用的杀虫剂逐渐下降到亚致死浓度。亚致死浓度的杀虫剂会影响害虫的生理和行为，可能导致害虫死灰复燃。本研究探讨了高效氯氰菊酯和茚虫威对实验种群的潜在亚致死效应。帕迪。茚虫威是一种相对较新的农药，其作用机制与高效氯氰菊酯不同。采用浸叶法测定了3种杀虫剂对蚜虫成虫的急性毒力，并构建了生命表，分析了高效氯氰菊酯（B-LC 10，B-LC 30）和茚虫威（I-LC 10，I-LC 30）2种亚致死浓度对蚜虫F0和F1代生长发育和生殖的影响。帕迪。分析结果表明，两种杀虫剂的亚致死浓度可显着降低F0代的繁殖力和寿命。此外，两种杀虫剂的亚致死浓度延长了下一代害虫的发展。生命表参数表明，在亚致死浓度的杀虫剂评价没有刺激蚜虫的繁殖潜力。这些信息对于在R.的管理计划中更有效地使用这些杀虫剂可能很重要。帕迪。
Abstract Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is a devastating pest of wheat worldwide. Beta-cypermethrin is widely used to control piercingsucking pest insects, including R. padi. Field-applied insecticides gradually descend to sublethal concentrations with the passage of time. Sublethal concentrations of insecticide may affect physiology and behavior of pests, potentially leading to pest resurgence. This study investigated potential sublethal effects of beta-cypermethrin and indoxacarb on an experimental population of R. padi. Indoxacarb is a relatively new pesticide with a mechanism of action that is different from that of beta-cypermethrin. The leaf dip method was used to test the acute toxicity of these insecticides to adult aphids, and life tables were constructed to analyze the effects of 2 sublethal concentrations of beta-cypermethrin (B-LC10, B-LC30) and indoxacarb (I-LC10, I-LC30) on the development and reproduction of the F0 and F1 generations of R. padi. Results of these analyses showed that sublethal concentrations of the 2 insecticides can significantly reduce the fecundity and longevity of the F0 generation. Also, sublethal concentrations of both insecticides prolonged the development of nymphs in the subsequent generation. Life table parameters demonstrated that the evaluated insecticides at sublethal concentrations did not stimulate aphid reproductive potential. This information could be important to enable a more effective use of these insecticides in management programs for R. padi.
