Xylella fastidiosa in Texas: Implications of a multiple vector, strain, and host plant system.

• Author(s): Bextine, Blake;
• Abstract: Xylella fastidiosa (Xf) causes Pierces disease (PD) of grapevine and is the single greatest limiting factor affecting grape production in the US. The recent establishment of Homalodisca vitripennis (Hv), an invasive vector species, in California has resulted in new epidemics of PD across the state. Much effort has contributed to understanding the relationships between Xf and Hv. However, Xf is transmitted by multiple vectors which impact the dispersal of the bacterium. This is especially true in the southwestern US, where Hv originated. Understanding the impact of multiple vectors, multiple Xf strain with variable host ranges, and host plant system will lead to management of this disease in different regions of the US.
