The community structure,dynamics of pest and predacous arthropod in a banana field

A survey of arthropod species including pests,predactious arthropod and neutral insects was did and 18 orders,74 families,181 species were found in the banana field in Nanning.Pest and spiders feature predominant subcommunities in banana arthropods.Stephanitis typica,Bagworm\|(Psychidae),Paratrechina bourbonica,Uloborus guangxiensis,Hylyphantes graminicola,Pardosa pusiola are the main components of the community in the banana plantation.The paper analysed the temporal and spatial structures of four subcommunities and its numeral dynamics as well as its relationships with the ecological environment in the banana fields.
