Stalkborers (maize, pink, chilo)

There are at least 14 species of cereal stalkborers that occur in Africa. The dull brown to copper night flying adult moths lay their eggs between the leaf sheath and the stalk of maize plants. The creamy or pale brown larvae (some species are more pink) can reach 25-40 mm in length.

Stalkborer larvae first feed on young unfolding leaves, resulting in irrgelular holes in the open leaves. Larvae will tunnel into the stalks and cobs with devastating results. These insects can attack maize, sorghum and sometimes even sugar cane.
