Without question, pest population assessment and decision making are among the most basic elements in any integrated pest management (IPM) program. In fact, these activities characterize state of the art approaches in pest technology and differentiate IPM from other strategies.
Forming the basis of assessment and decision making is bioeconomics, the study of the relationships between pest numbers, host responses to injury, and resultant economic losses (Pedigo 1996). The relationship of bioeconomics to other elements of an IPM system is shown in Figure 1.
