Triflumezopyrim, a new nicotinic acetylcholine receptor (nAChR) inhibition, can effectively control piercing-sucking insect pests such as white-backed planthopper (Sogatella furcifera). At present, there has been no reports on the effects of triflumezopyrim on the population growth and development of S. furcifera. In this experiment, an age-stage two-sex life table was used to evaluate the impact of triflumezopyrim on the biological parameters of S. furcifera. The results showed that the adult preoviposition period (APOP) and total preoviposition period (TPOP) of the F1 generation were significantly higher than those of the F0 and F4 generations, on the contrary the average fecundity, intrinsic rate of increase (r) and finite rate of increase (λ) of the F4 generation were higher than those of the F0 and F1 generations. The results of synergists and enzyme activities indicated that the CarE and P450 activities in the F4 generation were significantly higher than those in the F0 generation (P < 0.05). The protein contents of vitellogenin (Vg) and vitellogenin receptor (VgR) and relative expression quality of VgR in the F4 female adults were also significantly higher than those in the F0 generation (P < 0.05). These results showed that triflumezopyrim at a low concentration could promote the growth and reproduction of S. furcifera, and that may provide a reference for the rational use of triflumezopyrim in the future.

亚致死剂量的三氟甲嘧啶对白背飞虱Sogatella furcifera（半翅目：Delphacidae）的种群生长，发育和代谢酶的影响。

新型烟碱乙酰胆碱受体（nAChR）抑制作用Triflumezopyrim可有效控制刺吸性害虫，例如白背飞虱（Sogatella furcifera）。目前，尚无关于三氟甲嘧啶对短链霉菌种群生长和发育的影响的报道。在该实验中，使用了一个年龄阶段的两性寿命表来评估三氟甲嘧啶对S. furcifera生物学参数的影响。结果表明，F1代的成年产卵前期（APOP）和总产卵前期（TPOP）明显高于F0和F4代，而平均生殖力，内在增长率（r）和有限F4代的增加率（λ）高于F0和F1代。增效剂和酶活性的结果表明，F4代的CarE和P450活性明显高于F0代（P <0.05）。F4雌性成虫中卵黄蛋白原（Vg）和卵黄蛋白原受体（VgR）的蛋白质含量以及VgR的相对表达质量也显着高于F0代（P <0.05）。这些结果表明，低浓度的三氟嘧啶可以促进糠S链球菌的生长和繁殖，为今后合理使用三氟嘧啶提供参考。F4雌性成虫中卵黄蛋白原（Vg）和卵黄蛋白原受体（VgR）的蛋白质含量以及VgR的相对表达质量也显着高于F0代（P <0.05）。这些结果表明，低浓度的三氟嘧啶可以促进糠S链球菌的生长和繁殖，为今后合理使用三氟嘧啶提供参考。F4雌性成虫中卵黄蛋白原（Vg）和卵黄蛋白原受体（VgR）的蛋白质含量以及VgR的相对表达质量也显着高于F0代（P <0.05）。这些结果表明，低浓度的三氟嘧啶可以促进糠S链球菌的生长和繁殖，为今后合理使用三氟嘧啶提供参考。
