Abstract

During investigations into shoot-fly damage to guinea corn (Sorghum bicolor), millet (Pennisetum typhoides) and maize (Zea mays) in rain-grown plots at Samaru during 1966, it became obvious that attack was not attributable to a single species (Atherigona varia var. soccata Rondani (=A. indica infuscata van Emden)), as was previously believed. This species is undoubtedly the principal pest of guinea corn seedlings and young plants in northern Nigeria (Map 1), but there are also many other species involved. During the following four years field trials were undertaken to establish the relative importance of the species within the area and to learn something of their biology.
