The optimal conditions for beet yellows virus (BYV) acquisition and transmission by Myzus persicae were studied. Maximum recorded retention of BYV in aphids was 48 h. Preacquisition starvation of aphids influenced positively transmission efficiency if the acquisition access feeding period was short (30 min to 2 h), but after a longer such period it was without influence. The efficiency of transmission also depended on the acquisition access feeding period. Maximum transmission efficiency of starved and nonstarved aphids occurred after 2 h (75%) and 4A6 h (65%) of acquisition, respectively.
