Contacts or sources of information – Myrie WA, Harrison NA, Douglas L, Helmick E, Gore-Francis J, Oropeza C, McLaughlin WA, 2014. First report of lethal yellowing disease associated with subgroup 16SrIV-A phytoplasmas in Antigua, West Indies. New Disease Reports 29, 12. [http://dx.doi.org/10.5197/j.2044-0588.2014.029.012]
Occurrence – Widespread losses of palms currently under way in Antigua is a result of recent spread of LY disease to the island. Dead and declining coconut palms with foliar symptoms suggestive of LY disease were identified at several locations throughout Antigua.
Spread – Widespread
Currently active areas - Several locations throughout Antigua
Suspected new outbreaks - not known
Other palm/plant hosts - Five trunk tissues from coconuts and a queen palm (Syagrus romanzoffiana) tested positive (20.7% of the sampled palms) and with positive results in 20 palms (69%) including at least one representative of six palm species. Nested PCR rDNA products (1.64 kb) in RFLP analysis produced fragment patterns that were indistinguishable, but could be differentiated from Texas Phoenix palm decline phytoplasma, representative of 16SrIV-D.
New hosts, new vectors, new strains or suspected loss of resistance - Bismarck palm (Bismarckia), royal palm (Roystonea regia) and foxtail palm (Wodyetia bifurcata), that had no prior history of susceptibility to LY, were infected.
Research projects - .not known
Rehabilitation/replanting programmes - not known
