In Guadeloupe the most efficient vector of citrusTristeza virus (CTV), Toxoptera citricidus, was discovered at the end of 1991. The distribution of this vector was determined based on surveys made in each locality of the archipelago. At the same time, the search for Tristeza disease by an ELISA test was undertaken and results were all negative. From now on, regular control of all the nurseries, in order to deliver only healthy material, and the use of resistant rootstock are highly recommended. An integrated control program against T. citricidus must also be started. Finally, it is necessary to continue the watch for citrus Tristeza virus (CTV) on a regular basis, so as to detect it as soon as it appears and take the immediate and necessary measures. Finally the general distribution of T. citricidus and CTV in the Caribbean area is presented. |
