会泽新松叶蜂Neodiprion huizeensis生物学特性观察

A BIOLOGICAL OBSERVATION ON NEODIPRION HUIZEENSIS

    摘要
  • 摘要: 会泽新松叶蜂Neodiprion huizeensis Xiao et Zhou是华山松的重要害虫。在云南会泽县一年发生2代,以预蛹期在地被物和表土内越冬。幼虫6龄,有群集性。长尾大麝鼩Crocidura dracula Thomas是害虫的有效捕食者,对茧蛹的捕食率在50%~90%之间。保护天敌、适当用药和人工剪除有虫枝是可行的防治措施。

     

    Abstract: The conifer sawfly Neodiprion huizeensis Xiao et Zhou is an important pest feeding on Pinus armandi.It has 2 generations a year in Huize County,Yunnan Province,and overwinters as prepupae under duff and litter or in loose soil.Larvae are gregarious,having 6 instars.The white-teeth shrew Crocidura dracula Thomas is an effective cocoon predator preying on the overwintering prepupae reaching a predation rate of 50%-90%.Protecting natural enemies,using pesticide properly and cutting off twigs bearing the aggregated larvae are feasible prevention and control measures.
