摘要:   为筛选出对井上蛀果斑螟有高杀虫活性的药剂,在室内应用浸渍法和饲喂法,测定了氯虫苯甲酰胺、虫螨腈和啶虫脒3种杀虫剂对井上蛀果斑螟卵、初孵幼虫和老熟幼虫的杀灭作用及对其存活虫态化蛹和羽化的影响。结果表明,20%啶虫脒可湿性粉剂8 000倍液处理卵后,卵的孵化率显著降低,较对照下降48.54%;5%氯虫苯甲酰胺悬浮剂和10%虫螨腈悬浮剂对卵的孵化抑制效果较差。5%氯虫苯甲酰胺悬浮剂1 000倍液处理初孵幼虫72 h后死亡率为77.82%,显著高于其余2种药剂各浓度处理,其存活幼虫的化蛹率和成虫羽化率分别较对照降低63.54%、42.07%,显著低于其余2种药剂各浓度处理。10%虫螨腈悬浮剂1 500倍液处理老熟幼虫后24 h的死亡率为76.21%,药后72 h的死亡率为81.06%,均显著高于其余2种药剂各浓度处理,其存活幼虫的化蛹率和成虫羽化率显著低于20%啶虫脒可湿性粉剂各浓度处理,但与5%氯虫苯甲酰胺悬浮剂1 000倍液处理无显著差别。以上结果表明,5%氯虫苯甲酰胺对初孵幼虫具有高的杀虫活性,且对其后续虫态化蛹和羽化有较好的抑制作用,10%虫螨腈对老熟幼虫具有较高的速效杀虫活性,20%啶虫脒的杀卵效果优于5%氯虫苯甲酰胺和10%虫螨腈,但对幼虫活性低。

Abstract: In order to screen out effective insecticides with high insecticidal activity against Assara inouei Yamanaka,under laboratory conditions,immersion method and feeding method were used to determine the direct lethality of three insecticides,chlorantraniliprole,chlorfenapyr and acetamiprid,on the eggs,newly hatched larvae and mature larvae of Assara inouei,and their influence on the pupation and emergence of subsequent developmental stages.The results showed that 20% acetamiprid WP 8 000 times solution could significantly reduce the hatching rate of eggs,and the hatching rate of eggs decreased by 48.54% compared with the control;5% chlorantraniliprole and 10% chlorfenapyr had a poor inhibitory effect on egg hatching.The mortality rate of 5% chlorantraniliprole SC 1 000 times solution after treatment of newly hatched larvae for 72 h was 77.82%,which was significantly higher than those of the treatments with the other two insecticide;The pupation rate of the surviving larvae and emergence rate of adult were reduced by 63.54% and 42.07%,respectively,compared with the control,and were significantly lower than those of the treatments with the other two insecticide.10% chlorfenapyr SC 1 500 times solution treatment of mature larvae,the mortality rate after 24 h was 76.21%,and the mortality rate after 72 h was 81.06%,which was significantly higher than those of the concentration treatments of the other two insecticide;The
pupation rate of the surviving larvae and emergence rate of adult were significantly lower than those of the treatments with 20% acetamiprid WP,but there was no significant difference with 5% chlorantraniliprole SC 1 000 times solution treatment.These results indicate that 5% chlorantraniliprole has high insecticidal activity against newly hatched larvae,and has a good inhibitory effect on the pupation and emergence of subsequent developmental stages;10% chlorfenapyr has higher fast-acting insecticidal activity against mature larvae;The ovicidal effect of 20% acetamiprid is better than 5% chlorantraniliprole and 10% chlorfenapyr,but has low activity against larvae.
