The potential adventive geographic range of glassy-winged sharpshooter, Homalodisca coagulata and the grape pathogen Xylella fastidiosa: implications for California and other grape growing regions of the world

摘要: Abstract The invasion risk posed by the xylem feeding hemipteran, Homalodisca coagulata (native to southeast USA and northeast Mexico, a recent invader of California (USA) Tahiti) xylem-dwelling phytopathogenic bacterium, Xylella fastidiosa Americas causative agent Pierce's disease grape vines), was examined using computer climate modeling program CLIMEX. Model predictions indicated that suitable climatic conditions for H. causing strains X. exist in almost all production areas world, may be able colonize unsuitable fastidiosa. Additionally, model regions north will unable sustain populations both pests because cold stress, irrigation agricultural urban California's deserts has removed dry stress limitations, which when combined with depauperate natural enemy fauna most likely facilitated successful coagulata. CLIMEX predicted accumulation would exclude from France northern central producing Spain Italy. This result is incongruous reports Kosovo Balkans suggest cold-tolerant cause could exhibit potential establish Europe contrary results reported here.
