Abstract: | Summary In laboratory experiments PLRV transmission byMyzus persicae Sulz was shown to be possible even during a very brief feeding period onPhysalis floridana Rydb, in both acquisition and inoculation feeding. When the acquisition feeding time (AFT) was varied between 30 sec and 48 h the inoculation feeding time (IFT) was constant (48h) and vice versa: when the AFT was constant (48 h), the IFT was variable. The rate of infection was 2.2% following 30 sec AFT and 1.1% after 30 sec IFT. After 1 min feeding these infection rates increased to 7.9% and 1.8% respectively. The capacity for virus transmission was closely correlated with the increase in feeding time for both acquisition and inoculation feeding. |
