Abstract: Pest management methods should be durable, ecologically stable, flexible and feasible for meeting the demands from the idea of sustainable development of agriculture and forestry. Herein the authors suggest a new way of pest management——a strategy of using mutual plants to regulate the interactions of biotic factors around the environment of the target plant, i.e. mutualistic plant protection (MPP). MPP means that a plant could produce a most output by the regulations of plants, animals, microorganisms, and other associated factors in the adjacent areas to maintain pest populations in a long-term stable status. The principle of feasibility of these regulation methods is the law of the mutual relationship of all organisms including plants and pests in the natural world. The conception of MPP could be a trend in the future plant protection.

Key words: mutual plant, mutualistc plant protection (MPP), pest management
