Research between ARS and the Cooperator aims to elucidate the genetic mechanism that control key aspects of European corn borer ecology and behavior; European corn borer male response to female pheromones and larval duration of diapause.
This research will take a genomics approach to determine the genome region and genes involved in determining European corn borer male response to female pheromones and larval duration of diapause. Specifically, this will entail generating phenotypic data for male response in males by the Cooperator using specialized wind tunnel equipment. Additionally, the Cooperator will acquire phenotypic data from univoltine populations present at their location and not accessible to ARS. Whole genome re-sequencing data will be collected from European corn borers assigned respective phenotypes, and resulting sequencing read data aligned to a draft genome assembly generated by ARS. The Cooperator will assess the degree of nucleotide diversity across the entire European corn borer genome and identify those regions (genes) correlated with male pheromone response and larval diapause duration.
