Characterization of wing development genes in the potato psyllid (Bactericera cockerelli) for RNAi-based management program

The potato psyllid (Bactericera cockerelli) has been identified as the primary vector of the phytopathogenic bacterium Candidatus Liberibacter psyllaurous (C. Ls), the causal agent of Zebra Chip in potatoes. Identifying potential target genes within this vector provides potential tools for insect management in the potato industry. Several genes involved in the patterning, growth, and differentiation of the wing in Drosophila melanogaster (common fruit fly) have been identified, either through genetic studies or genome-wide microarray analysis. In this study, wing development gene homologues were obtained for the Potato psyllid through polymerase chain reaction (PCR) and DNA sequencing. Due to the crucial role wings play in the dispersal of the Potato psyllid and therefore Liberibacter, regulation of wing development genes may potentially lower the severe economic losses felt by the potato industry as a result of the Zebra Chip disease.
