To assess the likely impact of climate change on aphid pest incidence - CC0304

Since global warming will have an impact upon the aphid problems currently encountered by British agriculture, as well as the viruses that they transmit, research is required to determine and forecast their likely effect on crop production. This study will analyse the long term historical database resulting from the Rothamsted Insect Survey, which relates to numbers and phenology of migrant aphids throughout Britain over a period of up to 27 years, in order to determine possible outcomes of a warmer climate. Feasibility of using the database to monitor biological effects of a changed climate will also be examined. Potential impacts of climate change on the status of aphid pests and virus vectors will be evaluated for current UK crops, while ways in which such changes may be monitored will also be studied. The study will identify statistical associations between historical suction trap data and some meteorological values. It will also further understanding of the associations between phenology of range of aphid species, including important vectors of plant virus diseases, and different climatic variables, both individually and in combination. In addition, the project may have implications for more theoretical areas of population biology with regard to the role of climate in population regulation.

To identify the potential impact of climate change on the status of aphid pests and virus vectors on current UK crops. To determine how such changes may be monitored.
