Biocontrol of agricultural pests is an old but very sound practice. It was practiced by the early Chinese. Conventional pesticides, used on a long term and heavy dose to control pests, are meeting with increasing undesirable side-effects and environmental problems, e. g., pesticidal residual, environmental contamination and the damage to wildlife etc. The utilization of natural enemies for the control insect pests will play an important role. Thus, modern insect pest management aims at minimal use of insecticides and to achieve safer and more effective control of insect pests through ecological knowledge of the pests, preservation ,rearing and release of their natural enemies, as well as developing various control measures which can be integrated into crop system to suppress the pest populations below economic damage levels. Recently, owing to the coming of the age of ecological conservation, biocontrol is found to possess their properties of high ecological selectivity, and big compatibility with different control agents. The utilization of natural enemy for the control of insect pests became to be emphasized items. Therefore, the purposes of this paper is to report the past and recent research and development of the application for the natural enemies in Taiwan. Under the cooperation with foreign research institutes, we will work on the exploitation and improvement of biocontrol, and will deeply improve the techniques of field evaluation and mass release of natural enemy for insect pest control. Finally, compare the farm system of foreign country which has temperate climate with the farm system of Taiwan which has tropic and subtropic climate, try to explore their properties and differences, and to find their effects on the availability of natural enemy. The results may offer a few ideas to improve biocontrol application in Taiwan.
