Introduction: The economic or action threshold is dependent upon several factors such as the cost of treatment, the price of the commodity, the injury rate of the pest, and the risk of incorrect sampling data. This sampling and threshold calculator takes all these factors into account and provides a seqential decision making tool for pest control. If the sampling density is near the threshold, then sequentially MORE samples are needed before a decision to treat can be recommended.
