Abstract: The composition and structure of arthropod community in mango field were investigated in this study, and the characterization of arthropod was also described. They will enrich the theoretical foundation for ecological of pests in mango orchard. The composition and diversity of arthropod communities in mango orchards were investigated in Hui'an country, Fujian Province, China in this study. The results showed that all the collected arthropod individuals belong to 2 classes, 17 orders, 80 families and 203 species. Among them, 106 species were herbivores (52.22%), 31 species were predators and parasitoids (15.27%), 14 species were detritivores (6.90%) and 52 species were spiders (25.62%). The main dominant herbivores were Tropidothorax elegans Distant and Recilia dorsalis (Motschlsky), and the main dominant predators and parasitoids were Tetrastichus coccinellae Kurju-mov and Tetramorium guineense Fabricius, and the main dominant detritivores was Musicdae, and the main dominant spiders was Phintella sp.1.
