The glassy-winged sharpshooter (Homalodisca coagulate) and smoke tree sharpshooter (Homalodisca lacerta) are creating economic problems in California in agricultural and ornamental plantings. The greatest threats surround their ability to spread the bacterium Xylella fastidiosa, causing Pierce’s disease in grapevines, almond leaf scorch disease, and oleander leaf scorch. Other diseases caused by strains of X. fastidiosa may have an even greater impact in the future.
