Abstract Three fertilizer application treatments (chemical fertilizer, half chemical fertilizer and biogas manure, and biogas plus cake manure) were adopted under equal N, P (P O ) and K (K O) rates to study the effects of biogas manure on yield of eggplant 2 5 2 and structure of arthropod community and continuous cropping obstacles in eggplant fields. In 2009, arthropods of treatment A got 22 species which belonged to 21 families, arthropods of treatment B got 24 species which belonged to 23 families, arthropods of treatment C got 24 species which belonged to 23 families. Phytophage of three treatments were prominent parts, dominant species were Myzus persicae and Henosepilachnavigintioctopunctata; Dominant species of predacious sub-community were Propyleajaponicaand Araneaventricocus. In 2010, arthropods of treatment A got 21 species which belonged to 20 families, arthropods of treatment B got 24 species which belonged to 23 families, arthropods of treatment C got 24 species which belonged to 23 families. Phytophage of three treatments were prominent parts, dominant species were Myzus persicae and Henosepilachna vigintioctopunctata; Dominant species of predacious sub-community were Tarantulas and Aranea ventricocus. In 2009 and 2010, diversities index of phytophage and parasitoids-neutralities were not significantly different in three treatments; Diversities index of treatment A were significantly different from treatment B and C in arthropods, phytophage and predacious sub-community. Caused by climate factors, indexes of every communities fluctuated. Change tendency of every index of arthropods were as same as phytophage, and that of predacious sub-community and parasitoids-Neutra
