Study on Community Structure of Arthropod in Wheat Field

[Objective]The aim was to elucidate change law of dominant species in community.[Method]Systematic analysis method was adopted to study species composition,properties,community richness,evenness,diversity,concentration and temporal dynamics of arthropod in wheat field.[Result]The results showed that there are 33 species arthropod animals at middle and late stage in Hefei region wheat filed.The total number is 10 027,belonging to 15 orders,25 family;insecta includes 18 family,arachnida is 7.Among which,natural enemies include 13 family,pests family is 8,neutral insects family is 4,including 28 species.The major dominant species of non-asian community are Lipaphis erysimi and Thrip,richness are 0.623 50,0.111 49 respectively;the main dominant of natural enemies sub-community stocks are Leis axyridis and Theridion octomaguLatum,richness are 0.250 482 and 0.191 715 respectively.Four indexes of arthropod communities displayed regulation.The law of richness index and diversity index were more significant.[Conclusion]The study will provide theoretical basis for integrated control of wheat pests.
