Using Population Genomics to Reveal Temporal Patterns of Host Use in the Cotton Fleahopper (Pseudatomoscelis seriatus)

The cotton fleahopper (Pseudatomoscelis seriatus) is a mirid pest of commercial cotton with over 100 known host plants across its range.  Here, we use next generation sequencing (ddRAD-seq), to elucidate patterns of gene flow between focal cotton populations of CFH with nearby populations of CFH that are associated with an important overwintering host plant, woolly croton (Croton capitatus).
