Viruses causing severe mosaic, epinasty, defoliation, and premature death of Passiflora spp. were isolated from west central Colombia. Western blot analyses indicated the presence of potyviruses. Two Colombian isolates (COL-22 and -GR) were compared to known potyviruses as to host range, symptoma...

One group of bean diseases with characteristic virus symptoms is the mosaic group, frequently associated with leaf and plant malformations and green and yellow stippling. Insect vectors belong to the families Chrysomelidae, Coccinelidae, and Meloidae. This group of virus contains the bean souther...
Un grupo de enfermedades del frijol con sintomas caracteristicos de los producidos por los virus es el de los mosaicos, frecuentemente asociados con deformaciones de las hojas y de las plantas y moteado verde o amarillo. Los insectos vectores son de las familias Chrysomelidae, Coccinelidae y Melo...
Since 1967, many diseases have been associated with mycoplasma- like microorganisms (MLM), especially when symptoms have been characterized by general plant chlorosis, stunting, excessive proliferation of branches (witches' broom), bud proliferation and disorders of floral organs (phyllody and vi...
Desde 1967, muchas enfermedades se han asociado con los microorganismos semejantes a micoplasmas (MSM) especialmente cuando los sintomas se han caracterizado por una clorosis general de la planta, raquitismo, proliferacion excesiva de ramas (superbrotamiento) y desordenes en los organos florales ...
Bean crops are attacked by several viruses transmitted by insects among which are: (1) beet curly top virus (Circulifer tenellus); the best control measure is the utilization of resistant var.; (2) the tobacco yellow dwarf virus (Orosius argentatus); (3) the tomato spotted wilt virus, which is tr...
El cultivo del frijol es atacado por varios virus transmitidos por insectos, entre los cuales estan: 1) el virus del apice rizado de la remolacha (Circulifer tenellus); la mejor medida de control es el uso de var. resistentes; 2) la muerte de verano del frijol (Orosius argentatus); 3) el virus de...
The inheritance of the ability of Sogatodes oryzicola to support replication of the rice hoja blanca virus (RHBV) was studied by following the segregation of progeny of crosses between insects of known pedigree and known ability to support virus replication and transmission. Virus transmission to...
