Technical Abstract: Insects that are classified in the Order Hemiptera have become one of the most important plant-associated insect taxa, mainly because of their ability to transmit plant pathogens. The glassy-winged sharpshooter is the primary vector of the plant-infecting bacterium Xylella fastidiosa, the causal agent of Pierce’s disease of grapevine. The potato psyllid, another hemipteran insect, is the primary vector of the plant-infecting Candidatus Liberibacter solanacearum, the causal agent of Zebra Chip of Potato. The Asian Citrus Psyllid, yet another hemipteran insect, is the primary vector of Candidatus Liberibacter asiaticus, the causal agent of huanglongbing which is devastating citrus production worldwide. The study of these insects at the genomic and epigenomic level can provide basic biological information towards understanding the genetic basis of disease epidemiology, insecticide resistance, and the insect/bacterium/plant interactions. With this increased understanding more effective management strategies of these pests and diseases will be developed.
