摘要
2017年在北京洋白蜡上发现多孔横沟象Pimelocerus perforatus为害树干,这种象甲在中国分布较广,国内一直用名大粒横沟象Dyscerus cribripennis。本文记述了多孔横沟象的形态特征、寄主、对洋白蜡的为害,讨论了大粒横沟象的学名问题,并提供多孔横沟象的成虫和幼虫期形态(包括雄性外生殖器)、为害状等彩图。
Pimelocerus perforatus(Roelofs)was found as a new pest of the green ash Fraxinus pennsylvanica in Beijing in 2017.It was widely distributed in China under the name of Dyscerus cribripennis.This paper describes the morphology,host plants of P.perforatus,its damage to the green ash,discusses the identity of D.cribripennis,and provides color pictures of the weevil’s adult(including male genitals),larva and pupa.
