Abstract: 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 in 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 alter-natives 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, the application 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 nec-essary.
