        abstract = {We examine the optimal time-variant refuge policy to manage pest resistance to Bt crops
in afinite-horizon discrete-time model. We identify analytically the intertemporal effects of
refuge fields on the pest population and its susceptibility. The shape of the optimal refuge
policy and whether or not pest susceptibility should be exhausted completely at the end
of the time horizon depend crucially on the values of a cost premium of Bt seeds and the
fitness cost of resistance (over-mortality of resistant pests) and are addressed via numerical
simulations. We demonstrate the importance of modeling the dynamics of the biological
system accurately, of defining a diploid (and not haploid) biological model, and of using a
discrete-time (rather than continuous-time) framework.}
