A Primary Study On The Diversity Of Elateridae Insects In The Leigong Moutain National Nature Reserve Of Guizhou Province

Elateridae is the largest family in the superfamily,Elateroidea,and one of the main pests in agriculture,forest,fruit and greening industries.Research on Elateridae is of great economic value and ecological significance.We surveyed and analyzed the community diversity of Elateridae beetles for Mountain Leigon using Shannon-wiener information diversity index,Pielou evenness index,Margalef species richness index and Jaccard similarity index.The results are listed as follows:(1)A total of 363 Elateridae beetles were collected,belonging to 39 species and 17 genera in 8 subfamilies.(2)The Shannon-Wiener Information Diversity Index and Margalef Species Richness Index of the Elateridae insects at different altitudes ranged from 1300 m to 1500 m,and the lowest are from 1500 m to 1700 m,while the Simpson Dominance Index and Pielou Uniformity Index reached 1500 m.In the range of 1500m-1700 m,the Simpson dominance index is at least 1300m-1500 m,and the Pielou uniformity index is at least 1300m;The Jaccard similarity index for Elateridae beetles is highest in the range of 1300 m ~ 1500 m and is low in the ranges of 1300 m ~ 1500 m and 1500 m ~ 1700 m.(3)The Shannon-Wiener Information Diversity Index of the Elateridae in different months the highest is May and the lowest is June;the Simpson Dominance Index is the highest in June and the lowest is July;the Pielou Uniformity Index is the largest in May,the smallest is June;the Margalef species richness index is the highest in July and the lowest is September;The Jaccard similarity index are large August and September,and smaller in April and July and July and September.(4)The Shannon-Wiener information diversity index and Margalef species richness index highest are deciduous broad-leaved forests and the lowest are subtropical coniferous forests;the Simpson dominance and Pielou evenness index highest are subtropical Coniferous forest,the lowest is deciduous broad-leaved forest;The Jaccard similarity index for Elateridae beetles is higher in deciduous broad-leaved forest and evergreen broad-leaved forest,evergreen broad-leaved forest and coniferous broad-leaved forest,and is smaller in conifer-broad mixed forest and subtropical coniferous forest.(5)There are 39 Elateridae species collected in this survey.According to the species accumulation analysis,the sampling of survey was adequate.The analysis of the dominant species in the protected area showed that the dominant species are Agrypnus gypsatus and Elater sinensis,while the others are common and rare species.(6)The fauna analysis for Elateridae insects of the Mountain Leigong are dominant with the southwestern fauna,and most correlated with southern China,central China,northern China,northeastern China,Qinghai-Tibet and Mengxin fauna.
