oa Journal of the Entomological Society of Southern Africa - Further notes on the overwintering of the green peach aphid, Myzus persicae (Sulzer), in South Africa



The green peach aphid, Myzus persicae (Sulzer), is one of the most efficient vectors of plant viruses. In South Africa, this species has attracted much attention during recent years because of its role as vector of the potato leaf roll disease. Since M. persicae lives on many host plants before, during and after the potato season, it is of equal importance to know its bionomics on these plants as it is on potatoes. Abundance and proximity of these determine, among other factors, the time of appearance and the numbers of M. persicae on potatoes, and consequently the spread of leaf roll and other aphid transmitted potato viruses.
