Factors to be considered in refining a general model of economic threshold

  • H. C. Chiang


A general model of economic threshold was developed in 1979 on the basis of the European corn borer in Minnesota. It has been tested and adopted on various insects in Europe and South America. On the basis of these experiences and other studies in Minnesota, the model has now been refined to consider the factors of plant stress, host tolerance and insect phenology.
