Question of the Week: Pierce’s Disease

Last week the question was:  Which disease has infected this muscadine vine?


This is a bacterial disease called Pierce’s disease, Xylella fastidiosa.  Pierce’s disease is vectored by leafhoppers, primarily the glassy winged sharpshooter.  The bacteria clog the xylem tissue in the plant decreasing water flow which leads to the scorch-like symptoms on the leaves.  Muscadines handle Pierce’s disease fairly well and will normally survive, however, Xylella is a very serious problem on other crops.  For more information, look here.


Here is this week’s question:  What will this nymph grow up to be?
