SUMMARY A study was made of the resistance of three wild potato species, Solanum chacoense, S. stoloniferum and S. demissum , to three aphid species, namely Myzus persicae (Sulz.), Aulacorthum solani (Kalt.) and Macrosiphum euphorbiae (Thomas), which all commonly infest the cultivated potato, S. tuberosum . The resistance of each Solanum species differed with the species of aphid, with the part of the plant and with the physiological condition of the leaf. As a result, it may be difficult to utilize such resistance, since it is ineffective against some of the pest aphid species and may break down as the physiological condition of the plant changes.
