oa Journal of the Entomological Society of Southern Africa - Notes on the occurrence of holocyclic overwintering of the green peach aphid in South Africa



The green peach aphid, Myzus persicae (Sulzer), is known as an injurious insect on many plants from most parts of South Africa. Additionally, its presence in potato fields where heavy leaf roll and virus Y infections occur, leads one to believe that it plays an important part in the spread of virus infections. In spite of the great economic importance of this species its biology under South African conditions has not yet been studied. A program of research on its biology and ecology, with special emphasis on its importance as a vector of potato virus diseases, was therefore started in 1956.
