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...

The South American forage legume Arachis pintoi was found to be affected by foliar ring spot symptoms in surveys of various localities in the Cauca Valley of Colombia. A filamentous virus (approximately 750 nm) isolated from symptomatic A. pintoi plants induced the characteristic ring spot sympto...

All commercially grown bean var. in Central America of small shiny red grain type are susceptible to one or more strains of BCMV. An attempt was made to recombine the important var. characteristics of var. such as Honduras 46, Rojo Zamorano, Nahuizalco, Rojo de Seda, and Desarrural, in addition t...

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...
