The citrus rust mite game: A simulation model of pest losses
Environmental Entomology 10 (2), 171-176
Abstract: The citrus rust mite game (CRM GAME) is an interactive simulation algorithm for estimating citrus yield loss to the rust mite. Losses occur due to increased fruit drop and decreased fruit size of damaged (russetted) fruit. There is no single economic threshold of mites at which a pesticide should be applied. Instead, a range of damage thresholds can equal a spray cost depending upon crop value, timing of pest attack, timing of harvest and temperature. Mean percent surface damage of 5 to 20% equals the cost of a pesticide application depending upon the particular situation. Since the emphasis must be on prevention of the loss, predictive capability of the pest population is implicit in the concept of economic thresholds for agricultural pests.
