Africa

The following pest species are reported for sorghum crops in northern Mali.^[2]

• Atherigona soccata (sorghum shoot fly, a major pest): The larvae cut the growing point of the sorghum leaf.
• Agonoscelis pubescens is also reported as a sorghum pest.
• Busseola fusca (maize stem-borer; Lepidoptera, Noctuidae) attacks maize and sorghum, and occurs especially at higher altitudes. It is a common pest in East Africa, but has also spread to West Africa.
• Chilo partellus (spotted stem-borer; Lepidoptera, Crambidae): introduced, from East Africa but spreading. The larvae attack sorghum and maize. Present at low and mid altitudes.
• Contarinia sorghicola (sorghum midge or cecidomyie du sorgho in French; Diptera, Cecidomyiidae): The adult resembles mosquitoes. Larvae feed on developing ovaries of sorghum grains.
• Melanaphis sacchari (sugar cane aphid) attacks sorghum.

Sitophilus zeamais (maize weevil) and Sitotroga cerealella (Angoumois grain moth) attack stored sorghum and maize.^[2]
