%X This paper studied the effects of triazophos,shachongshuang,abamectin,and Bt + imidacloprid on the insect pest-natural enemy community in early rice fields in the Yangtze-Huaihe region of Anhui Province.The results showed that all of the test insecticides had significant effects in controlling the growth of major insect pest populations.The average value of insect pest-natural enemy community diversity under effects of triazophos,shachongshuang,abamectin,and Bt+imidacloprid was 1.545,1.562,1.691 and 1.915,respectively,while that in control plot was 1.897.After two weeks of applying insecticides,the plots applied with shachongshuang and abamectin had a similar composition of insect pest-natural enemy community,but the community composition was significantly different between the plots applied with triazophos and Bt + imidacloprid.From the viewpoints of community stability and pest control,Bt + imidacloprid had the best effect,and shachongshuang and abamectin were better than triazophos.
