摘要
元宝槭潜叶叶蜂1988年首次发现于山东泰山.一年发生1代,以6龄老熟幼虫在地下土茧内滞育越夏、越冬.平均发育历期,卵7.3天,幼虫23.4天,蛹21天.翌年5月化蛹、羽化.该虫发生量与气候条件紧密相关.幼虫期可用50%久效磷乳油2000倍液、40%氧化乐果乳油1400倍液喷冠防治,效果可达90%以上;用以上两种药剂的原液树干打孔防治效果均在90%以上;用40%氧化乐果乳油5倍液树干涂环防治效果可达90%.
Messa acericola Xiao,found first on the Mount Tai of Shandong Province in 1988,overwinters with the 6th instar larva in earth-cocoon under ground,pupating and emerging in May of the following year.Its incidence rate is closely related to the climate con- ditions and control could be made at the larval stage by spraying the tree crown with 50% monocrotophos 2000X or 40% omethoate 1400X,resulting in more than 90% larvae killed. Injecting into bored holes of trunk with the above two chemicals or smearing round the trunk with 40% omethoate 5X could kill 90% larvae.
