Occurrence and relative incidence of viruses infecting papaya in Venezuela

Abstract:

A survey of the main papaya (Carica papaya L.) production fields in Venezuela during 1997, indicated that crops were heavily affected with various virus-like symptoms. A total of 745 samples from papaya plants showing symptoms suggestive of virus infection were collected and analysed using electron microscopy and enzyme-linked immunosorbent assay (ELISA). Papaya ringspot virus (PRSV) and Papaya mild yellowing virus (PMYV) were the most frequently found viruses, which also occurred, in mixed infections. Rhabdovirus-like particles were found only in samples collected in Distrito Federal (D.F). Papaya mosaic virus (papMV) and Tomato spotted wild virus (TSWV) were not detected during the survey.
