For each population the state of origin, year collected, source, diapause status, response to Cry3Bb1, and intra-population genetic diversity (π) are given. Diapause status indicates whether or not the population undergoes diapause. All non-diapause (“No”) populations derive this phenotype from the Brookings, SD source. All field sourced populations diapause. Response to Cry3Bb1 was determined by larval recovery data in single plant bioassays under laboratory conditions. Each population was reared on Cry3Bb1 expressing (treatment) and isoline (control) maize. Populations with at least 80% relative survival on treatment when compared to control were defined as low response, while medium response populations ranged between 20% and 80%, and high response populations were less than 20% relative survival. Missing data is indicated by NA.
