| 摘 要： | 为了使水稻害虫综合治理提高到系统工程的水平,作者在室内30℃恒温下,测定了褐飞虱和八斑球腹蛛各发育阶段的虫(蛛)体组织潜能量、生殖生产量、呼吸量、蜕及蛛丝含能量。根据晚稻田褐飞虱和八斑球腹蛛种群数量的系统调查结果,以及水稻生物量与热值的测定值,给出了水稻-褐飞虱-八斑球腹蛛生态系统的能量流动图,分析了该生态系统的净生态效率、对光能或潜能的利用效率和生物量、能量生态锥体。

| Abstract: | The energy budgets for all development stages of brown planthopper (bph), Nilaparvate lugens, and Theridion octomaculatum were estimated at 30c. Their growth production, egg production, respiiation and energy content of exuvia and webbing were determined.Based on a systematic survey of population number of bph and T.octomaculatum, and the determination of biomass and energy of rice during late lice, the energy flow chart for rice-bph-T. octomaculatum ecosystem was given. The net production efficiency, ecological efficiency of energy utilzation, and pyramids of biomass and energy in this ecosystem were analysed. |
