Analysis of Insect Species Composition and Species Diversity in Limu Mountain Area
From March 2022 to June 2023,survey methods including line transect method,trap lamp survey,sweep net survey and attractant survey were used to investigate the insect class organisms in Limu Mountain,and the species composition and diversity of insect class organisms in Limu Mountain were analyzed.The results showed that there were a total of 238 species of insects in 167 genera,45 families and 12 orders in the Limu Mountain area of Hainan Tropical Rainforest National Park.Lepidoptera was the dominant group,containing 27 family groups,account-ing for 60.00%of the total number of families;containing 142 genera,accounting for 85.03%of the total genera;there were 213 species,ac-counting for 89.50%of the total number of species.The species diversity index showed that the Margalef richness index(D)of Lepidoptera was the highest,which was 23.2948,the Shannon-Wiener diversity index(H′)was the highest,which was 5.2909,and the Pielou evenness index(J)was slightly different.The analysis showed that the biological layout of Lepidoptera in the Limu Mountain area of Hainan Tropical Rainforest National Park had absolute advantages,and had a rich species number and complex diversity structure.
