死浓度氯虫苯甲酰胺可降低亚洲玉米螟种群增长
Chlorantraniliprole at sublethal concentrations may reduce the population growth of the Asian corn borer,Ostrinia furnacalis (Lepidoptera: Pyralidae)
摘要
Abstract
In order to provide a scientific basis for understanding the effects of the insecticide chlorantraniliprole on Ostrinia furnacalis (Guenée),diet-incorporation bioassays were used to examine the toxicity of chlorantraniliprole to O.furnacalis,and the sublethal effects of the insecticide were investigated using life table analyses under laboratory conditions.The results showed that the LC10,LC40,and LC50 values of chlorantraniliprole on the 3rd instar larvae of O.furnacalis were 0.038,0.098,and 0.123 mg a.i./L,respectively.After the 3rd instar larvae were treated with LC10 and LC40 levels of chlorantraniliprole,the larval and pupal development were significantly delayed,adult longevity was significantly decreased and fecundity also decreased compared to the control,but the pupal weight (female:P =0.337,male:P =0.121),egg hatchability (P =0.087) and sex ratio (P =0.379) were not affected.Reproduction parameters,such as the net reproductive rate (R0),intrinsic rate of increase (rm),and finite rate of increase (λ) in the treatment groups were significantly lower than those in the control group.These results suggest that the LC10 and LC40 concentrations of chlorantraniliprole may reduce the population growth of O.furnacalis.关键词
