Glassy-winged Sharpshooter Transmission of Xylella fastidiosa to Plants

摘要

Xylella fastidiosa is a xylem-limited bacterium that causes disease in many plants such as grape, almond, citrus, and coffee (Hopkins and Purcell 2002). Insect dissemination of X. fastidiosa is only possible by xylem-feeding vectors belonging to the subfamily Cic-adellinae (Hemiptera, Cicadellidae; sharpshooter leafhoppers) and the family Cercopidae (Hemiptera; spittlebugs) (Redak et al. 2004). Several insects within these groups are vectors of X. fastidiosa; however, their transmission efficiency is variable and dependent on many factors (Purcell 1989).
