Abstract: When a pest population is monitored through time, two questions must be answered: (1) does the pest density exceed a threshold that dictates management action now?, and (2) if the density is below the threshold now, when should the population be sampled again? This chapter describes a method for pest monitoring that answers these two questions and is not encumbered by the requirement that pest trajectories follow a specific model, although knowledge of potential pest population growth is needed. The procedure is based on classifying pest density into one of three categories: (i) low density, indicating that damaging pest levels are unlikely to occur in the near future and hence sampling the population again can be delayed; (ii) intermediate density, showing that densities are not currently at a damaging level, but the population should be sampled again soon to make sure this is still the case; and (iii) high density, requiring immediate action. Future perspectives for monitoring are discussed.
