Studies On The Dynamics Of The Pest And Natural Enemy Communities In Boskage Of Konglin

The investigation of insect community was conducted from 2004 April toOctober in Konglin ,Qufu. The main contents and conclusions are as follow:The community was divided into four sub-communities:phytophapes,predators, parasitorids and neutralities by the standard of nutrition andhunting. The structures and dynamics of arthropod community and differentThe structures and dynamics of boskage of konglin and differentsub-communities were analyzed bu using a number of communityparameters.The results indicated that there were 147 species of arthropodcommunity belonging to 75 families, including 91 species of phytophagesrepresenting 47 families;27 species of predators repesentiang 15 families;18species of parasitorids representing 5 families;11species of neutralitiesrepresenting 8 families in boskage of konglin .The relative abundance ofphytophages and predators were 97.6% and 2.85% respectively. so it can beseen that the phytophages dominated the boskage communities. The dominantconcentration of phytophages was larger than of predatorsand prasitoids.Theother parameters such as diversity index (H')and diversity index(Hill)includingN1,N2,indicated the same trends, showing in the order: predatorssub-community>arthropod community> phytophages sub-community.The shifting trend of the individual number of phytophages was similar tothe arthropod community .both trends had two pesks that occurred at similar time.This indicated that the individual number lf arthropod community wasinfluenced mainly by phytophages.The numerical characteristics of insect community in the boskage ofkonglin,such as ecological dominance, species richness, community diversityand evenness were analysiszed .the structure characteristics lf the insect...
