First report of Xylella fastidiosa infecting coffee in Costa Rica
In 1995, severe symptoms were observed on 'Caturra' and 'Catuai' coffee (Coffea arabica) cultivars in farms in the southern part of the Central Valley in Costa Rica. Symptoms included reduced leaf size, malformation of leaves, curling of leaf edges,shortening of internodes and severe leaf chlorotic mosaic. The abortion of flowers and young beans was also observed, with a reduction in yield. Plants showed irregular growth with an atypical curling appearance. ELISA analysis revealed that 34.5 and 23.8 percent of Graphocephala permagna and Erythrogonia sonora specimens, respectively, that were collected from the area were positive for Xylella fastidiosa. This is thought to be the first report of X. fastidiosa in coffee in Costa Rica.
