Ground-Dwelling Insect Community and Its Relationship with Boundary Habitat in Chengdu Tianfu International Airport
Mastering the occurrence of insects in the airport is of great importance to the prevention and control of bird strikes in the airport.From March 2022 to February 2023,the characteristics of ground-dwelling insects in the lawn of Tianfu International Airport were investigated to explore the distribution differences of ground-dwelling insects between the lawns adjacent to the four boundary habitats outside the airport and the lawns at different distance gradients from the bound-ary.The results showed that:(1)A total of 119 species of insects belonging to 101 genera,49 families and 10 orders were identified,and the dominant groups were Orthoptera,Hymenoptera,Coleoptera and Diptera.(2)There was no significant difference in the dominance and diversity index of ground insects between the lawns adjacent to different boundary habi-tats.The species richness ranking of the ground-dwelling insects was:the lawn adjacent to woodland>the lawn adjacent to shrub land>the lawn adjacent to farmland>the lawn adjacent to bare land.The species richness of the lawn adjacent to shrub land and woodland was significantly higher than that adjacent to bare land.The abundance ranking of the ground-dwelling insect species was:the lawn adjacent to woodland>the lawn adjacent to farmland>the lawn adjacent to shrub land>the lawn adjacent to bare land.The abundance of the lawn adjacent to woodland was significantly higher than that adja-cent to bare land.(3)According to the different distance gradients,the richness,abundance and diversity of the ground-dwelling insects showed a decreasing trend from the airport boundary to the interior of the lawn,while the trend of domi-nance was opposite.(4)The richness and abundance of the ground-dwelling insects were the highest in summer and the lowest in winter.In winter,Orthoptera and Diptera were the dominant species,while Orthoptera,Hymenoptera and Cole-optera were the dominant in summer and autumn.The results provide a scientific basis for the comprehensive control of in-sects in airports.
