摘要
【目的】研究噻虫嗪与氯虫苯甲酰胺两种药剂,对非靶标害虫土耳其斯坦叶螨生长发育及种群参数的影响。【方法】采用玻片浸渍法、叶碟法,研究土耳其斯坦叶螨对两种药剂的敏感性、生命参数变化。【结果】经氯虫苯甲酰胺和噻虫嗪处理的土耳其斯坦叶螨成螨死亡率与对照均无明显差异;氯虫苯甲酰胺处理叶螨成螨后,次代除若Ⅱ期外,未成熟期的存活率均高于对照,而噻虫嗪处理时,次代若Ⅱ期的存活率高于对照,卵期、幼螨期和若Ⅰ期的存活率低于对照;经氯虫苯甲酰胺处理后,与对照和噻虫嗪处理相比,产卵前期明显缩短,世代显著延长,且日产卵量显著增多;氯虫苯甲酰胺处理的种群净增殖率R_0、内禀增长率r_m、周限增长率λ比对照和噻虫嗪处理增大,而施用噻虫嗪的叶螨平均世代历期T、种群加倍时间t比对照和施用氯虫苯甲酰胺延长。【结论】氯虫苯甲酰胺有刺激土耳其斯坦叶螨增长的作用,而噻虫嗪无影响。
【Objective】 This project aims to study the effects of two kinds of pesticides: Thiamazine and Chlorantraniliprole on the growing development and population parameters of non-target pest Tetranychus turkestani.【Method】The sensitivity and life parameters of two kinds of pesticides in T. turkestani were studied by slide-dip methods and leaf disc test.【Result】 There was no significant difference between the mortality rate of T. turkestani treated with Chlorantraniliprole and Thiamethoxam and the control;T. turkestani treated with Chlorantraniliprole, except for phase II, the survival rate in the immature phase was higher than that of the control, and when treated by Thiamethoxam, the survival rate of phase II was higher than that of the control;the survival rate of egg phase, larva phase and the survival rate of phase I was lower than those of the control, after the treatment with Chlorantraniliprole, the preoviposition period was significantly shorter and the generations extended significantly than those in the control and by Thiamethoxam treatment;In addition, the daily fecundity increased significantly;the net reproduction rates(R0)of the population treated with Chlorantraniliprole, the intrinsic rate of increase(rm), and the finite rate of increase(λ)were larger than those of the control and by Thiamethoxam treatment, while the mean generation times(T)treated with Thiamethoxam and the population doubling time(t)was prolonged than that of the control and by Chlorantraniliprole treatment.【Conclusion】Chlorantraniliprole can stimulate the growth of Tetranychus turkestani, but Thiamethoxam had no effect.
