%X Comparative studies on the arthropod communities between simple and complex litchi orchards were conducted in the suburb of Guangzhou.The Shannon Weiner index H' and the probability of interspecies encounter( PIE ) were used to describe and analyze the structure of arthropod communities.In the simple litchi orchard,phytophagous insects occupied 66.7% of the total arthropod community,predatory insects,parasitoids and spiders added up to 2.5% Whereas in the complex litchi orchard,phytophagous insects accounted for 42.7% of the total community,parasitoids 9.0%,predatory insects 7.9%,and spiders 12.8%.The richness of parasitoids,spiders,scavenger insects and predatory insects was higher in complex orchard than that in the simple orchard all over the year and less main pests were found in the complex orchard.The diversity indices of arthropod communities remained above 2.0 in the complex orchard and less than 2.0 in the simple orchard over the year.The higher diversity and eveness indices and less fluctuation were found in the complex orchard habitat.
