Preliminary analysis of pink bollworm population distributions in a large acreage of genetically engineered cotton with regard to resistance management

摘要

Resistance of PBW to the Bt toxin is currently managed using a specified percentage of tefugia and restricted pesticide use. We consider released, sterile PBW as pseudo-refugia. The mating of native and sterile moths prevents selection for resistance because the mating produces no offspring. We are investigating the role of sterile PBW as well as optimal dispersal of refugia as resistance management tactics.
