The system positioning observation and analysis of arthropod community structure and composition in hybrid aprum orchard, show that the pest species of hybrid aprum orchard is aphids,leaf mites,moth,scale insects,sucking,leaf-eating,etc..The most serious species is aphids,leaf mites,and the borer class,and the numbers of these three pests affect fruit production.Storage grass orchard predators are mainly the spider class,lady beetles and chrysopidae class,and these three hostiles have certain control function to the main insect pests and play an important role in maintaining the balance with their orchard pests and hostiles.The number of structure of each function groups,ecological advantage degree and diversity analysis show that intercropping forage orchard of arthropod community construction is more stable,all kinds of community index is relatively balance and natural enemy control is more obvious.Orchard integrated pest management should focus on the ecological control way using natural enemies to optimize the orchard biological community structure,improve the diversity and evenness,reduce community ecological dominance index,and enhance their ability to adjust control harm.Together with proper pesticide usage,it can gradually achieve the purpose of ecological control of orchard harmful biology.
