    Abstract

    The incidence and distribution of the sorghum head bug, E. oldi (Heteroptera: Miridae), and other panicle pests of sorghum in research stations and farmers' fields in West and Central Africa (WCA) were assessed during 1985-94. Maximum head bug abundance was observed during the dough stage. Head bug abundance was greater on improved cultivars (CSM 388, Malisor 84-7, ICSV 1063, ICSV 247 and ICSH 507), while the local sorghum cultivar guineense with long glumes was less susceptible, both at the research stations and in farmers' fields. Grain damage was moderate to severe, although farmers were mostly unaware of this insect and its damage potential because it remains hidden inside the panicle. Sorghum midge (Stenodiplosis sorghicola) damage was very high in farmers' fields in Burkina Faso, Niger, and Nigeria. The shootfly Atherigona soccata, stemborer Busseola fusca, grasshoppers, spittle bugs Locris rubens, Campylomma spp., Creontiades pallidus and Agonoscelis spp., head caterpillars Helicoverpa armigera, Pyroderces simplex and Eublemma gayneri, were other insect pests which damaged sorghum in the areas surveyed. It is proposed that future efforts in sorghum improvement for WCA should focus on developing cultivars with resistance to sorghum head bugs.
