David G. James

Associate Professor

Education

  • Bachelor of Science (Joint Honors, Zoology, Geography), University of Salford, UK 1975
  • Doctor of Philosophy, Macquarie University, Sydney, Australia, 1984

Specialization and Areas of Particular Interest

Biological control and integrated pest management in irrigated horticultural cropping systems. Current studies focus on understanding and using assemblages of endemic natural enemies to provide biological control and reduce pesticide use in hops and grapes.

Research is also being conducted on mite biology and ecology and the use of pheromones in insect management.
