In sequential transmission tests of Peanut stunt virus S (PSV-S) and Cucumber mosaic virus V (CMV-V) using Myzus persicae, these viruses behave as a semipersistent virus in Phaseolus vulgaris, but as a nonpersistent virus in Nicotiana tabacum, regardless of the species of plant used as the virus source. In addition, viruliferous aphids retained virus infectivity and transmitted it to P. vulgaris, even after they lost infectivity to N. tabacum. Apparently, the mode of transmission by the aphids differs depending on the plant species used for the assay. After mechanical inoculation with purified PSV-S or CMV-V, P. vulgaris appeared more susceptible to PSV-S than N. tabacum. However, the susceptibility to CMV-V appeared similar in both assay plants.

Key words : mode of aphid-transmission, Peanut stunt virus, Cucumber mosaic virus, Myzus persicae, Phaseolus vulgaris, Nicotiana tabacum.
