Members of the tribe Proco- niini have been identified as vectors of many dis- eases caused by the bacteria Xylella fastidiosa Wells et al. 1978, which occurs only in the xylem of plants (Marucci et al. 2002). Strains of X. fastidiosa cause diseases such as “Pierce’s Disease” (PD) in grape ( Vitis vinífera L.), “Phony Peach Disease” (PPD), “Coffee Leaf Scorch” (CLS), “Oleander Leaf Scorch” (OLS), and “Citrus Variegated Chlorosis” (CVC) among oth- ers. These incurable maladies produce substan- tial economic losses in a diverse variety of crops (Hernandez-Martinez et al. 2006). In South America the major threat is CVC which has spread rapidly throughout Brazil (Lopes 1996). X. fastidiosa is also present in United States, México, Venezuela, Brazil, Para- guay, Uruguay, Argentina (Redak et al. 2004), and Costa Rica (Aguilar et al. 2005
