Gaynor Malloch is a Research Scientist collaborating in studying pest arthropod biology on an international and national scale. She shares responsibility for implementing research objectives funded by RESAS, PCL, Bayer and Syngenta. She also supervises and teaches molecular techniques to PhD, MSc and BSc Hons students and visiting / temporary workers. 

Current research interests

The Scottish Myzus persicae population is being studied using molecular markers to define clones and superclones. The work has already demonstrated a severe genetic bottleneck with less than 20 major clones in the UK. Genotyping identifies several aphid properties including the presence of insecticide resistance mechanisms, host plant preferences and biological properties such as reproductive potential.

Other work includes laboratory and field virus epidemiology studies. Molecular techniques are being developed to determine the acquisition levels of mosaic potato viruses in various potential aphid vector species in field situations.

Past research

  • 2002-present: Research Associate at the James Hutton Institute. Shared responsibility for the research programme in molecular ecology. The current programme involves the molecular analysis of the virus vector aphid Myzus persicae and field virus epidemiology studies. The epidemiology field site is being used to assess the impact of these crop production methods on small mammal populations.
  • 1992 - 2002: Research Assistant at the Scottish Crop Research Institute, Dundee. Appointed to this position as part of a SERAD initiative to investigate aphid vector populations using molecular methods. The programme also involved the molecular analysis of population structures of raspberry beetle and their bacterial endosymbionts
  • 1987 - 1992: Assistant Scientific Officer in the Zoology Department of the Scottish Crop Research Institute. Provided technical support for a team studying the population dynamics of the potato cyst nematode Globodera pallida.

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
