Abstract
A simulation model of the population dynamics of Aproaerema modicella was developed in the early stages of the IPM research project. The model was specified with experimental and farm management data from India. It was linked to a dynamic programming procedure which indicated the number of insecticide applications needed to optimize income over ranges of natural mortality and host-plant resistance, and extended to include the initial level of the pest population, mortality caused by insecticides to natural enemies, the effectiveness of insecticide application, and groundnut prices. Model results indicated that future research should evaluate the effectiveness of farmers' insecticide applications. The initial population density had a significant influence on subsequent levels of damage. Effects of insecticides on natural enemies and groundnut prices were of less importance
