Ecological observations were made five times of the arboreal arthropod community in a 24-year-old Chamaecyparis obtusa plantation by using the fumigation method. Biomasses of primary consumers (herbivores and detritivores) ranged from 49 to 162 mg d.w./m^2. The biomass ratio of primary consumers to producers (the H/P ratio) fluctuated between 1.8×10^<-3>%. and 5.2×10^<-4>%. Biomasses of secondary consumers varied between 16 and 24 mg d.w./m^2,but they were relatively stable as compared with those of primary consumers. Secondary consumers attained to their maximum biomass after the primary consumers did after a delay of about three months. The linear regression between the mean body weight and individual numbers on the log-log scale was observed among the taxonomical orders belonging to primary consumers.
