Abstract

Although the citrus tristeza disease hls·been reported in Jamaica from 1959, severe strains of the virus was only confirmed in 1992 when a survey was conducted. Mild strains were widespread while severe ones were present in the two major citrus growing parishes, Manchester and St. Catherine. The discovery of the Brown Citrus Aphid (BrCA) in Jamaica and Cuba in 1993 resulted from a northward movement ofthe pest from Venezuela in 1976 into the Caribbean region in 1989. Over 90% ofJamaica's citrusorchards are established on sour orange rootstock, a cultivar which is highly susceptible to CTV, The presence ofall three factors- severe strains of the virus; BrCA an efficient vector of the virus, and highly susceptible cultivars as rootstock, makes an effective disease management system urgent and critieal, This paper discuss the programmes being considered.
