Maize (Zea mays) and itch grass (Rottboellia cochinchinensis) plants exhibiting a mild mosaic or mottle were collected from a farmer's field near Mokwa, Nigeria, in 1993. Icosahedral virions (approximately 28 to 30 nm) were purified from symptomatic tissue by differential centrifugation in 0.1 M ...

A new virus on maize in Nigeria: maize mild mottle virus
Maize streak geminivirus (MSV) isolates originating from maize, other cerealsand 18 grass species in Nigeria were characterized based on symptoms, transmission, host range and serological tests. All isolates could be transmitted to MSV-susceptible sweet corn cv. Golden Bantam using Cicadulina sto...

The survivorship, fecundity and development time (egg to adult) of Cicadulina storeyi China, C. arachidis China and C. ghaurii Dabrowski were studied at three constant temperatures (20, 25 and 30 .C). Additional tests were conducted to descriptionbe maize streak virus (MSV) transmission by C. ara...

Biology of Cicadulina species (Homoptera: Cicadellidae) and transmission of maize streak virus
Seven viruses are known on maize in tropical Africa, however, information is still scanty. MSV is widely distributed in sub-Saharan Africa; other viruses are less widely spread or only of local importance. Information on viruses and virus diseases is useful to plant breeders in setting priorities...
