Abstract

Observations made in Mali strongly suggest that Rice yellow mottle virus (RYMV) is spread by weaverbirds (Quelea quelea) below and around baobab trees (Adansonia digitata) in which they nest. Rice leaves in bird nests appeared to be infected. In Spain, an infection of Southern bean mosaic virus (SBMV) in string (climbing) beans (Phaseolus vulgaris) was apparently introduced and spread by sparrows (Passer domesticus) judging from the damage caused on flowers and bean pods. Damaged leaves and pods on SBMV-infected plants were also found in a screenhouse visited by sparrows and bulbuls (Pycnonotus barbatus) in Morocco. These observations showed that both viruses could be spread by birds when either collecting infected leaves for nesting or feeding on infected plants
