Community Structure and Diversity of Arthropod in Shelterbelt of Laogang ComprehensiveUtilization Base of Solid Waste

Arthropods were trapped in the Shelterbelt of Laogang Comprehensive Utilization Base for Solid Waste, Shanghai by the method ofMarkov network trapping from April to November 2018. Analysis were made on trapped arthropod by Shannon-Wiener index, Simpson index,evenness index and richness index in the terms of sub communities of different functional groups. The results showed that there were 15 599 insectswere collected, belonging to 133 families, 17 orders and 3 classes. Among them, Ichneumonidae had the most number of 2515, accounting for 16.12%of the total trapped insects. Shannon-Weiner index of arthropod community by different functional groups was ordered by total vommunity > pest subcommunity > neutral insect sub community > parasitic insect sub community > predatory natural enemy sub community. The dominance index,richness index and Shannon-Weiner index of the pest sub community was higher than that of natural enemy sub community, indicating that thestructure of latter was not stable as the pest sub community’s.
