This is the first record of Metopolophium dirhodum (WALKER) in Japan. Small colonies of the species were found in the oat fields of Kitami Agric. Exp.Stn., Hokkaido, in middle August of 1988. At this time, most colonies were composed of apterous viviparae and larvae, and only a few alate viviparae were observed. In a culture of the aphid on potted plants of oat, an ovipara and some apterous viviparae were produced in early October together with many alate viviparae (? gynoparae) and alate males. The occurrence of apterous form on secondary host in autumn suggests that the population might include monoecious clones. In addition to the biometric data of the four morphs mentioned above, diagnostic characters were given to distinguish the present species from other cereal aphids in Japan.
