| The cultivation of maize (Zea mays) has increased in recent years in the islands of the Western Indian Ocean region, especially in Mauritius where an important program of agricultural diversification is being implemented with the view of achieving self sufficiency in food requirements. The presence of six viruses, namely maize mosaic, maize streak, and sugarcane mosaic, have been observed. Three of the viruses, maize mosaic, maize stripe, and maize chlorotic stripe, are transmitter by the planthopper, Peregrinus maidis, while maize streak virus (MSV) is vectored by the leafhopper, Cicadulina mbila, and sugarcane mosaic virus and maize dwarf mosaic viruses are aphid-borne. MSV is considered to be the most important disease in Mauritius and Rodrigues, while in Reunion maize mosaic virus (MMV) is the most prevalent. MMV has been the most extensively studied virus and three strains, designated MMV-Fine (MMV-F), MMV-Coarse (MMV-C), and MMV-Broken (MMV-B), have been identified, while numerous host-adapted strains of MSV have been sorted out. A maize breeding program has produced hybrids resistant to MMV and MSV in Mauritius, while in Reunion cultivar Revolution or hybrids issuing from it, which are resistant to MSV, are cultivated. The causal agent of maize stripe has yet to be identified, and the pathogenicity of the 45 nm isometric particles associated with maize chlorotic stripe virus has to be proved. Studies have revealed that the disease referred to as maize line is in fact c aused by MMV-B. No maize-infecting mycoplasma or spiroplasma has been identified in the region. | |
