Studies on the transmission of pea leaf roll virus byMyzus persicae(Sulz.)

摘要

Factors affecting transmission of pea leaf roll virus by the aphidMyzus persicae(Sulz.) were studied. Results indicated that this virus exhibits properties consistent with those described for circulative viruses. The minimum feeding period for acquisition of the virus from infected leaves was from four to six hours, and for transmission to healthy plants between six and 24 hours. Aphids could infect plants for at least eight days after acquiring the virus.
