Key Words:agricultural pest; ecological and economic threshold; estimation method; index of pesticide ecological risk
Economic threshold (ET) was the key index for guiding agricultural pest management, which was based on the value of the saved crops and control cost in the pest management. Because the ecological cost of pesticide use often was less considered in the practical application, ET was lower and more pesticides were used. We proposed the concept of ecological and economic threshold (EET) with the aid of the new development in the assessment of ecological impacts of pesticide use, in which both the control cost and ecological cost of pesticide use were fully considered. The simple mathematic model and estimation method based on the  index of pesticide ecological risk use were presented. EET will be conducive to promote the pest management level and achieve purpose of pesticide reduction.
