中国蜂虻科系统分类研究

The bee flies, or Bombyliidae belongs to Brachycera, and constitute at the present time one of the large and diverse families of the order Diptera, nearly 5000 species are known, distributed among 221 genera and 16 subfamily. Because of the large size of the family and widely "overlapping" distributions, the genera play an important role in the study of zoogeographical problems. Aside from this, the parasitic role played by all members of the family makes them important in any study of hostparasite relationships and natural control. The role of pollination, usually of native plants, played by the bee flies is quite important, especially in the desert and semidesert region. The peculiarities in the distribution of bee flies throughout the China will be studied. Anthracinae is the biggest subfamily which has more than 2000 species, is about half the number of species of Bombyliidae. The genera are either limited in one specific realm, or mainly concentrated in one realm and sparsely scattered in other faunistical realms. China belongs faunisticlly to two zoogeographical realms - the Palaearctic Realm and the Oriental Realm. The species from the Palaearctic China Realm compose the principal part of Chinese fauna. Up till now, 12 papers were written, eight SCI papers was included, and 233 species distributed among 28 genera and 5 subfamily are known in China, 152 species in 27 genera were described by the applicant. This project will study and clarify the zoogeography, systematic and diversity of Bombyliidae from China, aim to understand the relationship of genera of the family by using method of comparative morphology and cladistic analyses, and reveal the bee flies system evolution. The phylogenetic relationships of Bombyliidae will be analyzed with PAUP 4.0 and Nona/WinClada.

蜂虻科是双翅目昆虫中种类最丰富的类群之一，具有重要的经济价值。其中有一些种类具有访花的习性，可用于传粉昆虫，特别是对半沙漠地带开花植物的传粉具有重要的意义；而有些种类是重要的天敌昆虫，如中华雏蜂虻Anastoechus chinensis Paramonov幼虫取食蝗虫卵块，对控制蝗虫数量和危害具有十分重要的作用。 申请者自攻读研究生以来一直从事蜂虻科系统分类研究，通过研究中国共有蜂虻科昆虫5亚科28属233种，其中作者发现4中国新记录属，54新种和10中国新记录种。本项目拟对我国蜂虻科昆虫的分类进行系统研究，阐清该科属种的多样性，揭示其地理分布格局；并运用比较形态学和支序分类学的原理和方法研究该科属之间的系统发育关系。研究结果对于开展该科昆虫多样性的保护和利用研究以及揭示蜂虻科的系统演化均具有重要的意义。

本项目对我国蜂虻科的分类系统进行研究，项目实施期间共发现中国蜂虻科昆虫新纪录属1个，新组合2个，新种15个；越南新纪录属3个新种2个，老挝新纪录属3个，研究结果丰富了亚洲蜂虻科昆虫区系；对蜂虻科昆虫种类进行系统修订，完成东方蜂虻属Euchariomyia的综述，对姬蜂虻属Systropus中国分布68个种进行特征整理和修改并完成分种检索表的修改和编制。与美国夏威夷毕效魄博物馆Neal Evenhuis研究员建立了紧密的合作关系，前往了美国Bishop博物馆并研究了其馆藏的12属19种中国分部的蜂虻科昆虫，同时拍摄其馆藏的蜂虻昆虫模式标本照片共计60属268种，和已鉴定的非模式标本372种，共计4000多张照片。通过野外观察记录研究以及文献资料整理完成蜂虻科昆虫寄生习性研究进展的综述，为今后对其作为蝗虫天敌昆虫保护和利用研究奠定了基础。还完成浙江天目山动物志和陕西秦岭昆虫志中蜂虻科昆虫的编写工作，分别系统记述分布在天目山的蜂虻科昆虫2属17种和分布于秦岭的蜂虻科昆虫6属13种，编制蜂虻科分属和各属分种的检索表，绘制整体或特征图。3年项目执行期间共计发表SCI论文2篇，中文核心期刊1篇，已接收的中文核心期刊1篇。
