- lepidopteran caterpillars are found feeding on developing grains: Autoba silicula, Cryptoblabes gnidiella, Cydia spp., Conogethes punctiferalis, Ephestia cautella, Eublemma spp., Euproctis limbata, Euproctis subnotata, Helicoverpa armigera
- maize cob borer Stenachroia elongella, especially in east India

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]
