Extract

Myzus persicae (Sulz.) has a wide range of possible host plants in Rhodesia though most may be physiologically unattractive to alate aphids that alight on them during the dry months of the year. Infested plants are difficult to find, yet as many winged aphids are trapped in the dry season (June) as in the wet (December). A wide dispersal of small colonies on a large variety of partially acceptable host plants during the dry season in therefore suggested. Potatoes and other garden plants may contribute to the population but tobacco regrowth is discounted as a source of aphids, though not of viruses.
