There are rich species in Mountain Tai,and the most abundant areas of biological resources in Shandong Province,but the study of insect community structure and diversity is very rare.In this paper,low altitude area was selected as our research object.To define the insect community in the area,includes community structure,temporal and spatial dynamic characteristics and species diversity of insect community,then we evaluate the ecological risk of lamp.The results could provide the basis insect ecology and diversity protection in the future.The results of the study are summarized as follows:1.After 2016,the insects in t he low altitude area of Taishan scenic area were trapped in the four peaches in the Taohuayu,Zhulinsi,Hongmen and Yingtaoyuan.The numbers were 17311,15264,14497,10545 respectively;4 pilot lights were seen in the insects in late March,in July and August to reach the peak,the number began to decrease in October,no insects occurred in late November.The peak period is longer of Taohuayu,and the occurrence of the peak when the number of the most,followed by Zhulinsi,Hongmen and yingtaoyuan.2.Taishan scenic low-altitude areas of light under the insects,four pilot were investigated to 8 head,46 kinds of 44 kinds of Taohuayu,Zhulinsi 46 Division 130,Hongmen 52 Branch 139,Cherry Park 51 Division 130;A total of 58 families of 181 species were identified in the low elevation area(see table for details).The structure of the insect community was higher in the low altitude area,among which the Lepidoptera,Coleoptera was the dominant species,the wild moth family and the genus was the dominant family.The insect community index showed a certain change correlation,diversity index And the change of the evenness index in the time series was positively correlated with the change of the dominance index,and the trend of the characteristic value of the four insects was basically the same.Light insects under the most diverse areas of Taohuayu,followed by Zhulinsi,Hongmenr,Yingtaoyuan.3.In this paper,a total of at least 18 species of natural enemies were found,among which the number of the Chrysoperla sinica was the largest,and the number of natural enemies in the Taohuayu(0.112013)was the largest among the insects in the whole lamp,followed by the Hongmen(0.108255),Zhulinsi(0.106421),Yingtaoyuan(0.101801).4.Through the search literature,we summarizes the information such as the control object, the fecundity and the predation of the natural enemies,and evaluates the trapping of the natural enemies by the report lamp,and the predator prey ratio about 1: 9.And put forward the improvement of the measured lamp by adjusting the time of measuring the lamp,strengthening the study of the compound eye structure of the pest and the natural enemy,and combining with other specificity.
