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.

Incidence of Citrus leprosis virus C and Orchid fleck dichorhavirus Citrus Strain in Mites of the Genus Brevipalpus in Mexico

Journal of Economic Entomology, 2020
Abstract The incidences of Citrus leprosis virus C (CiLV-C) and Orchid fleck dichorhavirus Citrus strain (OFV-citrus) were determined in field populations of Brevipalpus mites from 15 citrus-producing states in Mexico. Mites were collected from orange, grapefruit, mandarin, lime, and sweet lime orchards.

Transmission of Citrus leprosis virus C by the Mite, Brevipalpus yothersi (Acari: Tenuipalpidae), on Four Species of Citrus

Journal of Economic Entomology, 2019
Abstract Transmission of the virus, Citrus leprosis virus C (CiLV-C) (Cilevirus) by Brevipalpus yothersi Baker, on different citrus species was evaluated under greenhouse conditions. First, the relationship between acquisition access periods (AAPs; 1, 12, 24, 36, and 48 h) and virus concentration in mites was determined.

Preliminary Purification and Double Stranded RNA Analysis of Citrus Leprosis Virus [PDF]

International Organization of Citrus Virologists Conference Proceedings (1957-2010), 2000
ABSTRACT. Partial purification of citrus leprosis virus (CiLV) from local lesions of Cleopatramandarin was achieved using an extraction buffer of low molarity, viral precipitation with PEG-NaCl, and ultra-centrifugation in a 10 to 50% linear cesium sulfate gradient.
