| description | Whiteflies (Homoptera) are well known for their capacity to transmit 28 plant viruses of beans and other crops. Whitefly populations are generally restricted to tropical zones with alt. greater than 1300 m. Among the viruses transmitted there are: (1) BGMV is an economically important disease especially in regions of L.A., some parts of Central America and the Caribbean. Symptoms are clearly visible; the leaves take on a brilliant yellow or golden color. The virus can be transmitted artificially by inoculation. Diseases incidence can be reduced by eliminating alternative plant reservoirs of inoculum with crop rotation. Planting date should be Programmed so that young plants develop during periods of low temp and high moisture. Whiteflies can be controlled economically, applying insecticides in order to reduce the vector population and incidence of BGMV transmission. Plant resistance is an economical method of control. (2) Bean chlorotic mottle virus produces severe dwarfing of susceptible plants, accompanied by a high proliferation of buds and a bunchy or rosette type of plant development. (3) Euphorbia mosaic virus produces necrotic leaf lesions at feeding sites of whiteflies. (4) Rhynchosia mosaic virus includes a wide host range, causes leaf malformation, yellowing, witches'-broom and plant stunting in young plants. The symptoms and damage caused by the viruses are illustrated in color. (CIAT) |

(CIAT) Las moscas blancas (Homoptera) son ampliamente conocidas por su capacidad de transmitir 28 virus del frijol y otros cultivos. Las poblaciones de moscas blancas estan generalmente restringidas a las zonas tropicales con una alt. menor que 1300 m. Entre los virus transmitidos se destacan: 1) El BGMV es una enfermedad de importancia economica especialmente en las regiones de America Latina, algunas partes de America Central y el Caribe. Los sintomas son claramente visibles; las hojas toman un color amarillo brillante o dorado. El virus se puede transmitir artificialmente mediante inoculacion. La incidencia de la enfermedad se puede reducir mediante la eliminacion de fuentes alternas del inoculo con rotacion de cultivos. La fecha de siembra se debe programar para que las plantas jovenes se desarrollen durante los periodos de bajas temperaturas y alta humedad. La mosca blanca se puede controlar economicamente mediante la aplicacion de insecticidas, con el fin de disminuir las poblaciones del vector y la incidencia de la transmision del BGMV. La resistencia de la planta constituye un metodo de control economico. 2) El virus del moteado clorotico del frijol produce enanismo severo en las plantas susceptibles, junto con una gran proliferacion de yemas y un desarrollo de la planta en forma de racimo o roseta. 3) El virus del mosaico de las euforbiaceas produce lesiones necroticas en las hojas en los sitios de alimentacion de las moscas blancas. 4) El virus del mosaico de la Rhynchosia incluye un amplio rango de hospedantes, ocasiona deformacion y amarillamiento de las hojas, superbrotamiento y raquitismo de las planta jovenes. Se ilustran en color los sintomas y el dano causado por los virus.
