Abstract

Maize streak virus (MSV) disease is a sporadic but severe disease of maize in sub-Saharan Africa and is caused by a geminivirus which is persistently transmitted by Cicadulina leafhoppers (Homoptera: Cicadellidae) in a circulative manner (Efron et al., 1989). The Natural Resources Institute (NRI) has undertaken a major project to obtain information about the epidemiology of the disease, particularly the biology of the vectors and their interactions with the virus and host plants in order to develop strategies to control MSV disease. The feeding study of C. storeyi on an improved maize hybrid was undertaken with the International Institute of Tropical Agriculture (UTA) in order to identify vector resistance and to assess its effect on MSV transmission.
