摘要
落叶松毛虫(Dendrolimus superans)在春季大发生时多为3~6龄,可造成严重危害。通过使用噻虫胺·高效氯氟氰菊酯微囊悬浮剂对春季高龄幼虫进行防治试验,结果表明:使用该药剂稀释1000倍液防治3~6龄幼虫见效快、效果好;虫口密度不高时可采用1800倍液喷雾施药;防治3龄以下幼虫,可稀释2500倍液喷雾防治。
Dendrolimus superans are mostly 3-6 instars when they occur in spring,which can cause serious damage.Through the use of clothianidin and lambda-cyhalothrin microcapsule suspension to control the elderly larvae in spring,result shows that using this agent diluted 1000 times to control three to six instar larvae has a quick&optimal effect;when the insect population density is not high,it can be sprayed with 1800 times liquid;to control larvae below three instars,it can be diluted with 2500 times liquid for spray spraying.
