Previously fasted Myzus persicae was able to transmit the virus optimally after an acquisition feeding period of 2-5 minutes. Increased feeding time on virus source plants resulted in decreased transmission efficacy. The infectivity was lost either by 2 hours of post-acquisition fasting or by 20 minutes of, feeding on broccoli (Brassica oleracea var. italica). Although single aphid could inoculate PRSV to papaya seedlings, high infection rate (90-100%) was obtained when 5 and 10 insects were used. |
