Abstract
Many aphids are highly specific in their choice of food plant, feeding on only one species: others are less specific, feeding on a number of plants, which are, however, often closely related, Eight species are known which show very little specificity and all, in part because of this, are important pests. Six of these species are already known from East Africa, one of the others (NeomYZlIs circlImflexus) has an otherwise almost world-wide distribution and the eighth (MyzlIs ascaioniclIs), first described from England in 1946, has been rapidly extending its range ever since.
