Resumo: 	We examine producer behavior, resistance evolution, and returns under alternative refuge requirements in an eastern North Carolina region with multiple corn, cotton, and soybean fields infested by a mobile pest. Returns are highest, pyrethroid sprays occur least frequently, and pyrethroid resistance evolution is delayed most effectively with no refuge requirement. Complying with the current 20% refuge requirement costs the producer $8.67 per cotton acre, or $34.21 per non-transgenic insecticidal (Bt) cotton acre. Returns are highest under each refuge requirement when one-toxin Bt cotton is not phased out; however, removal of the technology at the earliest phase-out date minimizes regional pyrethroid sprays.
