基于比较形态学与几何形态学的中国皮蠹科系统分类研究

Dermestidae species consist of important stored product insect pests, which form the majority of species of this family, resulting remarkably quarantine issues. Worldwidely 145 genera and more than 1200 species have been reported, of which 15 genera 129 species are recorded from China. Due to morphological continuous variation and the vague morphological index among different taxon, the interspecific difference is hard to define. Additionally the classification of species and genera within this family are greatly confusing. Thus this project will carry out the systematic study of Dermestidae from China with acomprehensive utilization of comparative morphology and geometric morphology in order to establish a clear and efficient morphological index of genus and species. Meanwhile the species and the distribution of the Chinese Dermestidae insects will be reviewed and the key of genus and species based on the morphological characters will be rebuilt. The results will provide fundermental theoretical support for reconstructing phylogeny of Dermestidae, efficient control and inspection and quarantine of Dermestidae pests at ports.

皮蠹科是鞘翅目的一个重要类群，该科大多数种类是重要的仓储害虫和检疫害虫。全世界已知145属1200余种，我国已知15属129种。该类群形态的连续性变异比较普遍，不同阶元建立的形态指标模糊，种间差异很小，导致目前有的属是否应归属本科常有质疑，种类的属级分类比较混乱，种征的把握人云亦云。本项目拟针对上述问题开展我国皮蠹科的系统分类学研究，通过综合利用比较形态学与几何形态学手段，探讨属、种级形态指标，力求能初步建立两级阶元的形态指标体系，并据此系统厘定我国皮蠹科昆虫种类及其分布，重建以形态学特征为主要依据的属级、种级分类检索系统。研究结果将为进一步解决皮蠹科系统发育问题提供基础，同时为皮蠹的防治及口岸的检验检疫提供有力的科学依据。
