Glassy-winged sharpshooter (GWSS), Homolodisca coagulata, is a notorious pest in California because of it's ability to vector the bacterium, Xyllela fastidiosa, which causes Pierce's disease in grapes. At present it is not known whether GWSS in California originated from a domestic source or represents an invasive population of exotic origin. PCR-based Inter-Simple Sequence Repeat (ISSR) analysis and mitochondrial DNA sequence was used to examine genetic variation among geographical populations of GWSS.
