Abstract：
[Objectives] Hubei Wuling Mountains are rich in insect resources. Through the investigation of insect diversity in Laifeng county, Wuling Mountains, the insect diversity and population distribution in Wuling Mountains were clarified. In order to understand the threat factors of insect diversity in Laifeng county and put forward insect diversity conservation recommendations. [Methods] This experiment adopts transect survey method. The species and quantity of insects in Laifeng county, the diversity index of insects in the outbreak period and overwintering period, and the diversity index of Lepidoptera and Coleoptera collected locally were investigated. The research results obtained through the survey show that. [Results] A total of 397 species of insects of 15 orders, 101 families and 397 species of insects were collected and identified from Laifeng county, Wuling Mountains. The dominant insect groups in Laifeng county were: Lepidoptera, Coleoptera and Hemiptera basically include ornamental insects, natural enemy insects and pests. In the grid habitats, woodlands, woodlands and shrubs are more suitable for insect habitats. The grids with the highest Shannon-Wiener diversity index (H′) and Margalef richness index (ds) are all in Qidaohe village (53903090). [Conclusion] The threats to insect diversity in Laifeng county mainly include ore mining (54003130, Chenjiagou village), vehicle transportation (53903110, Yemao town) and indiscriminate application of chemical pesticides (54003120, Dafenshan village). It is suggested that Laifeng county should strengthen the coordination and cooperation of environmental protection departments and forestry departments, strengthen government supervision, protect local plants and greening, and strengthen the restoration of local insect habitats and protection of diversity.
