CITRUS LEPROSIS IN FLORIDA, USA, APPEARS TO HAVE BEEN CAUSED BY THE NUCLEAR TYPE OF CITRUS LEPROSIS VIRUS (CiLV-N)

VIRUS Reviews & Research, 2011
Citrus leprosis (CL) is a highly destructive viral disease vectored by Brevipalpus phoenicis Geijskes (Acari: Tenuipalpidae). It was first described in Florida in 1907 and last reported in 1968. CL was found after the 1920s in South America (Paraguay, Argentina and Brazil) and presently is known to occur in most of the South American countries.

Occurrence of Citrus leprosis virus in Llanos Orientales, Colombia

Plant Disease, 2006
In Colombia, citrus is cultivated in mostly small plantings that total 55,000 ha by approximately 25,000 farmers. Production includes 1,200 tons of fresh fruits and 60 tons of juice for domestic consumption, resulting in a net worth of US$650,000 per year. Most of the production comes from areas located between the Cordillera Occidental and Cordillera
