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.
