小蠹亚科的分类地位(鞘翅目,象虫科)

许多学者将小蠹作为象虫总科Curculionoidea中一个独立的科Scolytidae,而目前国际上普遍认为小蠹为象虫科Curculionidae中的一个亚科,即小蠹亚科Scolytinae。Erichson在1842年即提出了小蠹为象虫科的一个亚科,20世纪以R.A.Crowson为代表的学者对此观点表示支持并进行了较为严谨的科学论证,而以S.L.Wood为代表的另外一些学者则坚持小蠹的科级地位,我国学者蔡邦华、殷惠芬等一直沿用该分类系统。近20年来,国际上许多学者通过对小蠹类昆虫的成虫和幼虫外部特征的深入研究,以及支序系统学和分子生物学等一些最新结果,普遍认为小蠹类昆虫应为象虫科的一个亚科,这一观点已被国际上广泛接受。本文全面介绍了小蠹分类研究的历史及新的研究进展,并提出和建议采用"小蠹亚科"这一分类地位,与象虫亚科并列,均隶属于象虫科。

TAXONOMIC STATUS OF BARK BEETLES(COLEOPTERA,CURCULIONIDAE)

Many researchers recognized bark beetles as an independent family Scolytidae belonging to Curculionoidea.However,it is not in agreement with the internationally recognized taxonomic viewpoint,namely bark beetles should be a subfamily(Scolytinae) of Curculionidae.As early as 1842,Erichson primarily mentioned the proposal of Scolytinae,Crowsonsupported this view via rigorous study in his 1955’s paper.However,other taxonomists such as Wood stoutly insisted its family status.Chinese entomologist CAI Bang-Hua and YIN Hui-Fen followed Wood’s view.In resent 20 years,a series of latest researches of morphological,cladistics and molecular analysis on adults and larvae of the superfamily Curculionoidea all supported the status Scolytinae,and this view has been accepted extensively.The present paper elaborated the taxonomic history of bark beetles as well as new research progress,we here proposed and suggested bark beetles should be placed as one subfamily Scolytinae just like Curculioninae which all belonging to the family Curculionidae.
