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. date: 2012-09 date_type: published publisher: TSE Working Paper official_url: http://tse-fr.eu/pub/26138 faculty: tse divisions: tse language: en has_fulltext: TRUE view_date_year: 2012 full_text_status: public monograph_type: working_paper series: TSE Working Paper volume: 12-263 book_title: TSE Working Paper oai_identifier: oai:tse-fr.eu:26138 harvester_local_overwrite: faculty harvester_local_overwrite: site oai_lastmod: 2015-07-31T18:00:02Z oai_set: tse site: ut1 citation: Desquilbet, Marion and Hermann, Markus (2012) An assessment of bioeconomic modeling of pest resistance with new insights into dynamic refuge fields.
