dc.description.abstractCitrus tristeza virus (CTV) occurs in most citrus producing regions of the world, and it is the most serious viral pathogen of citrus. With the recent establishment of the brown citrus aphid, Toxoptera citricida, its most efficient vector, on Madeira Island (Portugal) and in Florida (USA) and the countries of the Caribbean Basin, the impact of CTV is likely to increase in these regions. Since there are many strains of CTV and CTV infections frequently occur as mixtures of several strains, it is necessary to be able to distinguish the strains for regulatory purposes, disease management and epidemiology. We describe the evolution of techniques developed to detect CTV and to differentiate the individual strains, and present the results of tests using these latest methods on CTV isolates from mainland Portugal, Madeira Island and Florida. Mild and decline-inducing strains of CTV were detected in mainland Portugal and mild, decline-inducing and severe stem pitting strains on Madeira Island. In Florida we demonstrated the presence of infections that reacted with probes made against stem pitting strains not previously detected there. It is concluded that CTV presents a significant threat to citrus production in mainland Portugal, on Madeira Island and in the neighbouring countries of the Mediterranean Basin, as well as in Florida, elsewhere in the USA and throughout the Caribbean Basin, especially following the widespread establishment of T. citricida throughout the region.
