Abstract:[Objectives] Lepidopteran species
in the family Limacodidae are among the main pests of plantation and urban
forestry. To clarify the relationship between community structure and
environmental factors in Beijing and surrounding areas, and thereby provide a
theoretical basis for forest pest control and ecosystem protection, we
investigated the phylogenetic diversity of 9 Limacodidae communities. [Methods] Samples were collected in the summer of
2010-2013 by lamp trapping and species identified using DNA barcoding technology. To
ensure the accuracy of species identification, morphological characteristics
were also used to identify species. Program R was used to calculate the
diversity index (including species richness and phylogenetic diversity), and
its correlation with 19 (Bio1-Bio19) environmental factors. [Results] Species diversity and phylogenetic
diversity differed among the 9 communities. Compared with the southern area,
the northern Yan-Shan area had higher species richness and phylogenetic
diversity, which might be related to floristic and climatic factors. The
phylogenetic diversity index was insensitive to different methods of
phylogenetic tree construction and genetic differences within species. There
was a significant positive correlation between phylogenetic diversity and the
seasonal variation of temperature in Beijing and surrounding areas. [Conclusion] The community structure of the Limacodidae in
Beijing and surrounding areas shows spatial differentiation. Seasonal changes
in temperature may increase environmental heterogeneity, which in turn affects
community phylogenetic diversity.
