Abstract

This paper presents the importance of aphids in potato production, especially in the seed potato production where they transmit potato viruses Y, A, X and PLRV. Among aphids, the most important vectors are the following aphid species: Myzus persicae - green peach aphid, Macrosiphum euphorbiae - potato aphid and Aulacorthum solani - glasshouse aphid. Aphids transmit potato viruses in two ways: non-persistent transmission and persistent transmission. Thus, knowledge of aphid population dynamics is important for deciding where, when, and how to grow and protect seed potato crops. Three common methods to study aphid populations are: aphid/plant counts, aphid/leaf counts, and yellow water traps. Direct control of virus spread is not feasible. Indirect control, however, helps to reduce virus transmission. This includes considering the growing area, agricultural practices, and chemical control. How efficiently virus transmission is controlled with aphicides depends on the type of virus transmission involved.
