Calculation of Economic-injury Levels and Economic Thresholds for Pest Management

摘要: General formulas for calculating economic-injury levels and economic thresholds are presented. Terms variables defined, important underlying assumptions explicitly described. Concepts regarding scheduling temporal dynamics presented to assist in proper use of the formulas. New that consider expanded concepts level threshold permit calculation multiple at a given time, dynamic change over multidimensional consist densities more than one life stage or species.
