Technical Abstract: The Asian citrus psyllid, Diaphorina citri Kuwayama and the potato psyllid Bactericera cockerelli (Sulc) are important vectors which spread bacterial agents causing Huanglongbing of citrus and Zebra Chip of Potato, respectively. These two diseases and vectors are recent invasive pests which continue to spread across the US. Management of both diseases is based on pesticide applications to suppress psyllid populations. Cytochrome 450 monooxygenases (P450s) constitute the largest class of insect detoxification enzymes. They participate in the protection of insects against both plant allelochemicals and insecticides. Because of their importance in mediating insecticide resistance and metabolizing plant secondary metabolites, we have identified and compared transcripts encoding Cytochrome P450 members in both psyllid species. Here, the repertoire and differences among Cytochrome P450 members are discussed. This is the first report of sequence comparison between these two economically important psyllids.
