Abstract:

Based on the data obtained form field surveys, this paper mainly deals with relationships between the pest and natural enemy guilds of arthropod communities and distribution characteristic of common arthropod species between in the canopy and lower layer of Phyllostachys heterocycla cv. Pubescens forest managed with five different measures, including long-term cultivation and fertilization, cultivation, weed cutting, non-management and herbicides application. The result indicates that, compared to the non-management forest, the common species of natural arthropod enemy between in the two forest layer decreased to some extent because of breakage of the undergrowths disturbed by other four management measures. These missed common arthropod species are largely in the categories of Arancuda and Hymenoptera. Thus, the mutual promotion effects of the natural enemies between the lower layer and the canopy have been weakened which might decrease the pests control use of the natural enemy and favor the pests outbreaks. So we can conclude that it is helpful to enhance the potential of pest control in a way of proper reservation of some undergrowths while implement of these management measures.
