A Preliminary Study on Insect Biodiversity in Meihua Mountain Natural Reserve

The species composition and diversity of insects in five different habitats located in Meihua Mountain natural reserve were surveyed.Approximately 5 000 specimens were collected and 193 species belonging to 14 orders,82 families were recognized.Shannon-wiener biodiversity index(H′),Pielou' eveness(E) and Species richness(S) were adopted to analyze the insect diversity difference in different communities.The results indicate that the richness,biodiversity index and eveness are distinctly different among different habitats.Coniferous-Broad Leaved Mixed Forest's insect diversity and eveness are the highest,evergreen broad-leaved forest's insect richness are higher than others;and bamboo forest's insect diversity,eveness and richness are the lowest.This is mainly related to the biological characteristics of insects and directly affected by habitat's species and eveness.
