溴虫腈对小菜蛾3龄幼虫存活、化蛹和羽化的影响
Effect of Chlorfenapyr on Survival, Pupation and Adult Emergence of the Third Instar Larvae of Diamondback moth, Plutella xylostella (Linnaeus)
摘要
Abstract
Together with the indoor toxicity test of chlorfenapyr to the third instar larvae of diamondback moth, Plutella xylostella ( Linnaeus, 1753 ) ( Lepidoptera: Yponomeutidae ), the effect of chlorfenapyr on survival, pupation and a-dult emergence of the tested insect was studied. The results showed that chlorfenapyr had no aftereffect on P. xylostella, and with the passage of time, mortalities at different concentrations had no obvious change. Larval weight, pupal weight, the duration of the third instar larvae to pupation and pupae were similar to the control in all treatment groups. All tested concentrations of chlorfenapyr caused decrease in pupation rate and adult emergence rate compared with the control. However, only the higher concentrations (10 and 20 mg·L-1 ) and 2. 5 mg·L-1 were significantly lower than the control, the lower concentrations ( 0. 625 and 1. 25 mg·L-1 ) and 5 mg·L-1 were not significantly different from the control.关键词
