世界性害虫棉蚜（Aphis gossypii，格洛弗）在世界范围内通过取食危害和传播病害给多种作物造成巨大的经济损失。氟吡呋酮是一种新型的丁烯酰亚胺类农药，其对A.用LC 25处理48 h后，估计棉蚜亲本世代（F0）。与对照相比，氟吡呋酮处理的F0代个体的成虫寿命和繁殖力没有显著降低。用生命表法研究了亚致死效应对F1代的影响。结果表明，与对照相比，四龄幼虫、成虫前期的发育时间以及整个生殖前期均明显延长，而繁殖力则明显下降。此外，LC 25处理组的F1的内禀增长率（r）、有限增长率（）和净繁殖率（R-0）均显著低于对照组。这些结果表明，亚致死浓度的氟啶呋喃酮对该虫种群增长有抑制作用。表明这种新型杀虫剂可能是一种有用的害虫管理工具。
The cosmopolitan pest Aphis gossypii (Glover) causes considerable economic losses on various crops by its feeding damage and transmitting diseases around the world. Flupyradifurone is a novel butenolide pesticide; its toxicity on A. gossypii parent generation (F0) was estimated following treatment with LC25 concentration for 48 h. The adult longevity and fecundity of the F0 individuals treated by flupyradifurone showed no significant decrease in comparison with the control. Life table method was used to evaluate the sublethal effects on progeny population (F1). Results showed that the development time of the fourth instar and the preadult as well as the total pre-reproductive period were significantly prolonged, while their fecundity was significantly decreased compared with the control. Additionally, the intrinsic rate of increase (r), the finite rate of increase (), and the net reproductive rate (R-0) of F1 were all significantly lower in the group treated by LC25 than in the control group. These results reveal that the sublethal concentration of flupyradifurone could suppress the population growth of A. gossypii and indicate that this novel insecticide may be as a useful tool in pest management.
