Predictive Models & Decision Support Systems for Virus Diseases and Aphid Vectors of Lupin and Canola

点击翻译按钮获取中文摘要

Aphids and the viruses they transmit cause major economic losses in legume and canola crops in Australia. This project will develop innovative predictive models and decision support systems (DSS's) for Beet western yellows virus and direct aphid feeding damage in canola and two types of Bean yellow mosaic virus in lupin, and a DSS for direct aphid feeding damage in lupin. These models will greatly improve understanding of factors driving virus epidemics and aphid outbreaks. Following extensive validation with data previously collected in the WA grainbelt, the predictive models and DSS's will be extended to end-users, resulting in considerable productivity gains, reduced costs and environmental benefits.
