ddRAD sequencing identifies insecticide resistance related loci and provides new insights into genetic structure of a plant pathogen vector, Bactericera cockerelli

Here, we used genomewide single nucleotide polymorphisms (SNPs) to investigate the genetic basis of resistance to neonicotinoid insecticides in resistant and susceptible potato psyllid populations collected across the potato-growing regions of the Southwestern USA. We were interested in elucidating the genetic structure of the potato psyllid population and exploring the hypothesis that the selective pressure of the neonicotinoid insecticide on the potato psyllid population could result in heritable SNPs. In addition, we attempted to explore the genetic strucuture of the psyllid populations that are designated as Central and Western haplotypes.
