MONITORING AND ADAPTIVE RESISTANCE MANAGEMENT

摘要: An adaptive management strategy can be used to hedge against failures in the scientific assumptions underlying high-dose plus refuge for managing resistance of European corn borer Bt corn. This will require sensitive monitoring coupled with effective interventions. Using a theoretical model, we suggest that recessive alleles must detected at frequencies ≤5 × 10−3 provide enough time adapt management. Analysis costs indicates an F2 screen is most cost method If dominant, in-field method. Both methods detect and measure ∼$5000 (U.S. dollars) per site. Two kinds responses taken: (1) reducing selective advantage allele or (2) modifying mating system so fewer are passed on future generations. Ass...
