Regional Analysis of Epidemics of Whitefly Transmitted Gemini Viruses in Cotton

M. R. Nelson, T. V. Orum, and A. Nadeem


Changes in sweet potato whitefly population dynamics has lead to increased prevalence and importance of two geminivirus diseases of cotton. In the Western Hemisphere the disease, cotton leaf crumple, has been the principle component of this problem while in Africa and Asia both leaf crumple and leaf curl are present. Regional spatial and temporal distribution of infection hazards for these diseases can be characterized by the use of Geographic information systems (GIS) and geostatistics.
