Study on insect community structure and diversity in Xiongan New Area based on lamp lure survey method

In order to deeply understand the structural characteristics and diversity of insect communities in Xiongan New Area, Using the black light lure method, insect communities in 23 townships of 3 counties in Xiongan New Area were collected and investigated, and their community composition structure, diversity characteristics and temporal dynamics in different regions were analyzed. the results show that: A total of 12551 insects belonging to 347 species and 97 families in 11 orders were attracted, including abundant species in the orders Lepidoptera, Coleoptera, and Hemiptera. The number of families and species of lepidoptera is the largest in Anxin, Rongcheng and Xiongxian counties. The Dawang Town in Anxin County has the highest diversity index and richness index and the lowest dominance index; Laotouhe Town of Anxin County has the highest superiority index, and the diversity index and richness index are the lowest; The highest uniformity index was in Zangang Town, Xiong County, and the lowest was in Beishakou Township, Xiong County. The number of insect families and individuals peaked in late July; The community diversity index and richness index are lowest in late June and higher in late July, while the dominance index is highest in early August and lower in early September. The evenness index fluctuates greatly in late June and early August, and is relatively stable in other months; The peak period of the temporal dynamics of absolute dominant groups and general dominant groups mainly occurred in late July, The lowest value of common insect species mainly appeared in late June, and the highest value mainly appeared in late July. In summary, the insect community in Xiongan New Area is relatively rich and has high stability.
