Interpretive Summary:

Technical Abstract: Technical Abstract: In Guatemala leprosis was detected around 1995 for the first time but, until two years ago, had not become a problem. It was detected for the first time in southern Guatemala, but now is widespread by that region. The symptoms of the disease are little different from the ones reported by Brazil: chlorotic spots but necrosis is around the rim, no necrosis is found in the center of the spot. At first, the symptoms in the fruit are chlorotic spots turning to necrotic spots with depressions. The branches also present necrotic rings. The symptoms have been found in sweet oranges and one variety of tangarine. Virus particles have been found in the cytoplasm of the cell, no particles have been found inside the nucleus by electron microscope. Some RT-PCRs have also been done. This disease seems to be local but tests to prove this are being done. The vectors found for this disease in Guatemala are mites from the species: Brevipalpis californicus and Brevipalpis phoenicius for the moment. The control measurements that are being used are cultural by sanitary pruning, eliminating all material with symptoms, as well as chemical control with mineral oil and an acaricide. It is recommended that workers do not visit uninfected fields if they visited the infected ones.
