Impact of pymetrozine on glassy-winged sharpshooter feeding behavior and rate of Xylella fastidiosa transmission

Glassy-winged Sharpshooter Transmission of Xylella fastidiosa to Plants

Transmission of phage by glassy-winged sharpshooters, a vector of Xylella fastidiosa

Xylella fastidiosa subsp. fastidiosa (Xff) is the causal agent of Pierce's Disease (PD) of grapevines and is vectored by the glassy-winged sharpshooter (GWSS, Homalodisca vitripennis). Previously we have reported the development of a bacteriophage (phage) based biocontrol system for PD, but no information on insect transmission of phages has been reported. Here we communicate that laboratory re...

Detection of the Bacterium, Xylella fastidiosa, in Saliva of Glassy-Winged Sharpshooter, Homalodisca vitripennis

Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), the glassy-winged sharpshooter, is one of the most important vectors of the bacterium, Xylella fastidiosa subsp. piercei (Xanthomonadales: Xanthomonadaceae) that causes Pierce's Disease in grapevines in California. In the present study we report a new method for studying pathogen transmission or probing behavior of H. vitripennis. When...

INSECT-SYMBIOTIC BACTERIA INHIBITORY TO XYLELLA FASTIDIOSA (PARATRANSGENESIS FOR CONTROL OF PIERCE’S DISEASE): IDENTIFICATION OF ENDOPHYTIC BACTERIA CYCLED BY GLASSY-WINGED SHARPSHOOTERS TO HOST PLANTS Project Leader:

INTRODUCTION Homalodisca coagulata Say, the glassy-winged sharpshooter (GWSS) is known to transmit the etiological agent of Pierce’s disease, Xylella fastidiosa. A paratransgenic approach designed to disrupt the ability of the insect vector to transmit the pathogen involves finding bacterial candidates that possess some degree of intimacy either within the insect and/or host plant xylem. Once a...
