A number of top down bio-control models have been proposed where thepredators' efficacy is enhanced via the provision of additional food (AF).These can lead to infinite time \emph{blow-up} of the predator . Predatorinterference, predator competition, refuge, pest defense and cannibalism havebeen proposed to achieve pest extinction, while keeping the predator populationbounded, but entail \emph{quadratic} or higher order damping terms. Thus an AFmodel with monotone pest dependent functional response, devoid of thesemechanisms, cannot yield the pest extinction state.  In the current manuscript we propose a novel patch driven bio-control model,with monotone pest dependent functional response. Here a predator is introducedinto a ``patch" such as a prairie strip with AF, and then disperses into aneighboring ``patch" such as a crop field, to target a pest. Assuming only\emph{linear} dispersal in the predator, we show, (i) blow-up in the predatorcan be prevented in both the prairie strip and the crop field, (ii) the pestextinction state is attainable in the crop field, (iii) the AF model with patchstructure can keep pest densities lower than the AF model without patchstructure and/or the classical top-down bio-control model, (iv) the AF modelwith patch structure possesses rich dynamics including chaos. In particular,one observes ``patch specific chaos" - the pest occupying the crop-field canoscillate chaotically, while the pest in the prairie strip oscillatesperiodically. We discuss these results in light of bio-control strategies thatwould utilize prairie strips.
