El Tomato spotted wilt virus (TSWV, género Tospovirus, familia Bunyaviridae) se transmite por trips de manera persistente y se encuentra distribuido alrededor del mundo causando graves pérdidas económicas en diversos cultivos. El TSWV tiene genoma tripartita de ARN con las siguientes características principales: el segmento largo (L) es de polaridad negativa y codifica para la polimerasa RNA dependiente (RdRP); el segmento mediano (M) codifica las glicoproteínas Gn y Gc que forman parte de la cápside y NSm involucrada en el movimiento viral; y el segmento pequeño (S) codifica las nucleoproteínas NSs implicadas en la actividad supresora del silenciamiento genético. En México, el TSWV ha causado grandes pérdidas en cultivos ornamentales y hortícolas, de... |

The disease caused by the viruses belonging to the genus Tospovirus is a serious problem in horticultural and ornamental crops in Brazil. In the field, this virus group is transmitted by the insect vector, thrips. Little is known about the thrips species occurring in Brazil, and which species are important for the dissemination of these diseases. For the study of epidemiology of this virus group, different thrips populations, which may have the capacity to be vectors of tospoviruses, were collected in the Federal District. Four species were identified: Frankliniella occidentalis Pergande, F. schultzei Trybom, Thrips palmi Karny and T. tabaci Lindeman. This is the first report of the occurrence of F. occidentalis and T. palmi in the Federal District. A... |
