Title: Research on Structure and Dominant Species of Chestnut Canopy Arthropod Community
Abstract: By field systematic investigation and,indoor trials,the characters of Chinese chestnut Canopy Arthropod Community structure was investigated using the knowledge and theory of community ecology.The research contents and results were listed as follows: Total 136 species of arthropods were observed,which belong to 12 Orders,63 Families.Among these species,there were 70 species of insect pests,62 species of natural enemies and 4 species of neutral insects,which account for 55.15%,41.39%,and 2.94%,respectively.Among 62 species of natural enemies,there were 15 species of parasitoids and 42 species of predatory arthropods,which account for 75.81% and 24.19%,respectively.The community could be divided into 3 nutrient classes,4 guilds and 11 groups.Herbivorous nutrient class was the most dominant in species and individual numbers.During fruit storage,the relative abundance of Dichocrocis punctiferalis Guenee was the greatest.
