拓宽生物防治　持续治理虫害

BROADENING THE SCOPE OF BIOLOGICAL CONTROL BY ALTERNATIVES TOWARDS SUSTAINABLE PEST MANAGEMENT

本文针对我国生物防治资源极其丰富和农民经济实力薄弱的特点，结合我国生物防治成果，论述了应如何发展和拓宽具有我国特色的害虫生物防治，进一步提高综合防治水平，促进农业可持续发展。

The paper deals with the possibility of adopting cultural and biological control in pest management towards sustainable agriculture on the bases of author's experience of IPM practice.China is rich in natural resources of beneficial insects. Chinese farmers possess the traditional experience of cultivation in agriculture management. So conservation and augmentation of natural enemies are deliberate action to protect and maintain natural enemy populations or to increase their beneficial effect in the agroecosystems. Biological control fits comfortably into sustainable agriculture. The low input, sustainable insect pest management is promising in China as well. The application and spread of biological control contribute to the development of sustainable pest management. The alternatives include the cultural management and plant resistance to insect pest, biotechnology for engineering, selecting and releasing parasitoids and predators, utilization of semiochemicals or natural products, theapplication of physiological and ecological selective pesticides. Mathematical modeling and systems analysis are to be expected to the integrated pest management. Interface of biological control with the basic sciences of entomology and education in pest management for farmers are necessary.
