Abstract: Field insect population survey indicated that the principal natural predation enemies of cotton bollworm (Helicover-pa armigera Hubner ) were EHngonidium graminicola Sundevall, Adonia variegata Goeze, Nabis sinoferus Hsiao. The results from experiments showed that the amount of prey consumed of these principal natural enemies in-creased when the density of prey rised, and decreased when the density of natural enemies increased. The predation function response fitted Holling's predation response equation 11 , and could be fit with the Disk Equation.

Key words: agroforestry system, carbon storage, carbon sequestration, structure optimization, climate change.
