OAR@ICRISATImportance of spittle bugs, Locris rubens (Erichson) and Poophilus costalis (Walker) on sorghum in West and Central Africa, with emphasis on NigeriaOAjayiauthorF AOboiteauthorLocris rubens (Erichson) (Cercopidae: Homoptera) and Poophilus costalis (Walker) (Aphrophoridae: Homoptera) are endemic pests of sorghum (Sorghum bicolor (L.) Moench) in Nigeria and some other countries in West and Central Africa. Other hosts are maize, pearl millet, rice, sugarcane, and grasses. On sorghum, L. rubens lays eggs in the epidermis of the leaf sheath. There are five nymphal instars and development from egg to adult takes about 33 days. Both species of spittle bugs feed on all growth stages and all parts of sorghum, including the panicle. Feeding symptoms include yellow leaf blotching. Severe infestations often kill young leaves and plants.Sorghum1999Association of Applied BiologistsArticle
