摘  要：
研究白龙江林区金龟总科的昆虫区系分布,是对该地区进行昆虫区划的重要依据。在白龙江林区内按不同海拔、林型定点采集金龟总科昆虫标本1 000余号,经鉴定,共有157种,隶属于9科,59属。该区系属的组成为:只属于古北界成分的占10.53%;只属于东洋界成分的占20.34%,二者共有种类占71.93%。该林区科的区系分布结果为,锹甲科中属于东洋界的种类占60.0%,古北、东洋界共有种类占40.0%;金龟科中古北界种类占41.67%,东洋界种类占33.33%,古北、东洋界共有种类占25.0%;花金龟科中古北界种类占16.67%,东洋界种类占37.5%,古北、东洋界共有种类占45.83%;丽金龟科中古北界种类占22.22%,东洋界和古北、东洋界共有种类各占38.89%;鳃金龟科中古北界种类占26.32%,东洋界种类占8.77%,古北、东洋界共有种类占64.91%。综合分析上述结果可知,白龙江林区金龟总科属、科的区系分布特点为:东洋界成分相对较多,古北界成分最少,以古北、东洋界共有成分为主。

摘  要：
Survey and inventory of Scarabaeoidea fauna in the Bailong River Forest Region of Gansu Province are important for zonation of insect fauna in this region.More than 1 000 Scarabaeoidea specimens were collected from different elevations and forest types of this region.After sorting and identification,these Scarabaeoidea beetles were found to belong to 157 species,59 genera,9 families.Based on the statistics of the faunal compositions,the Lucanidae consisted of 60.0% Oriental species,and 40.0% Palaearctic and Oriental common species;the Scarabaeidae consisted of 41.67% Palaearctic species,33.33% Oriental species,and 25.0% Palaearctic and Oriental common species;the Cetoniidae consisted of 16.67% Palaearctic species,37.5% Oriental species,and 45.83% Palaearctic and Oriental common species;the Rutelidae consisted of 22.22% Palaearctic species,38.89% Oriental species,and also 38.89% Palaearctic and Oriental common species;the Melolonthidae consisted of 26.32% Palaearctic species,8.77% Oriental species,and 64.91% Palaearctic and Oriental common species.The synthetic analysis of the faunal compositions at the genus and family level indicated that the Scarabaeoidea fauna of this region had the following characteristics:the Oriental composition was abundant,the Palaearctic composition was less abundant,and the Palaearctic and Oriental common composition was most abundant.
