摘要:

本研究旨在探讨新烟碱类杀虫剂苦参碱对桃蚜繁殖力的影响,试验采用叶浸法评估了苦参碱对桃蚜的毒力及亚致死剂量(LC10LC20LC30LC50LC70)对桃蚜成蚜繁殖力的影响。结果表明,苦参碱对桃蚜的LC50为9.66 mg/L,对桃蚜的LC10LC20LC30LC70分别为0.17、0.69、1.86、50.16 mg/L。苦参碱亚致死浓度可显著降低桃蚜成虫的繁殖力、寿命及存活率。LC10LC20LC30LC50LC70处理组中桃蚜成蚜的寿命比对照组分别缩短了0.9、1.4、1.9、3.1、4.1 d。亚致死浓度各处理组桃蚜的周限增殖率(λ)、净增值率(R0)、平均世代周期(T)、总生殖力(GRR)和内禀增长率(rm)都低于对照组。因此认为,苦参碱亚致死浓度对桃蚜有致死作用,不利于桃蚜种群的生长。

Abstract:

To understand the effects of the neonicotinoid insecticide martine on the fertility of peach aphids, this experiment evaluated the effects of martine toxicity and sublethal doses (LC10, LC20, LC30, LC50 and LC70) on adult aphids of Myzus persicae. The results showed that the LC50 of martine against Myzus persicae was 9.66 mg/L, and the LC10, LC20, LC30 and LC70 against Myzus persicae were 0.17, 0.69, 1.86, 50.16 mg/L, respectively. The sublethal concentration of martine can significantly reduce the fertility, longevity, and survival rate of adult Myzus persicae. The life span of adult Myzus persicae in LC10, LC20, LC30, LC50 and LC70 treatment groups was shortened by 0.9, 1.4, 1.9, 3.1 and 4.1 d, respectively. The limiting growth rate (λ), net value-added rate (R0), average generation period (T), total fertility (GRR), and intrinsic growth rate (rm) of Myzus persicae in sublethal concentration treatment groups were lower than those in the control group. It is concluded that the sublethal concentration of martine has a lethal effect on the growth of Myzus persicae population.
