Abstract
木瓜輪點病毒(Papaya ringspot virus)可經由下列六種蚜蟲一Aphis gossypii, A. madicaginis, A. nerii, Myzus persicae, Rhopalosiphum maidis和Sinomegoura citricola媒介傳播，其餵毒最適當時間為2-5分鐘，桃蚜經餵毒2分鐘後，再經過2小時飢餓處理即失去傳毒能力，或放置於青花菜(Brassica oleracea var. italica上餵食，經過20分鐘後即消失所帶病毒肥單隻桃蚜即可傳播病毒，5或10隻蚜虫集團接種，其傳毒力可達90~100%，故病毒與媒介蚜虫之關係為非永續性(Non-persistent)者。
In experiments carried out in the nethouse, the following six aphids, namely, Aphis gossypii, A. madicaginis, 4. nerii, Myzus pesicae, Rhopalosiphum, naidis. and Sinomegoura cit ricola, transmitted papaya ringspo t virus (PRSV). 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.
