Effects of Medium Regulation by Wastes on Insect Community at Tianjin Binhai International Airport

This study was conducted to explore the effects of medium regulation on insect community. Sludge compost,waste crumb rubber and fly ash were added in soil at the Tianjin Binhai International Airport. By sampling method,insect community and diversity were surveyed in Tianjin Binhai International Airport. The results showed that a total of 1 288 insects were collected,belonging to 8 orders,17 families and 21 species,with Orthoptera,Coleoptera and Diptera as the dominant groups. The species and individual numbers of insects showed the same trend with the order of sludge control fly ash crumb rubber. Compared with the control area,the individual number and species of insects in the crumb rubber area decreased by 41. 3% and 38. 9%,respectively. Moreover,the species richness and diversity of insects in the crumb rubber area were the lowest,1. 39 and 0. 46 lower than that of the control area,respectively,indicating that crumb rubber can effectively reduce the number and the diversity of insects at the airport.
