David James

Specialization and Areas of Interest

David James developed a passion for entomology at the age of 8 in England by rearing caterpillars in his bedroom. He studied Zoology at the University of Salford near Manchester, then migrated to Australia to work for the New South Wales Department of Agriculture on ways of controlling agricultural pests like locusts and mites. A PhD on the winter biology of Monarch butterflies in Sydney followed and a career as a biocontrol scientist in horticulture blossomed. David developed successful conservation biological control systems for stink bugs in citrus and for mites in pasture, grapes and peaches. In 1999, David became an Associate Professor at Washington State University at Prosser and worked on conservation biological control of insect and mite pests of hops and grapes. David has published more than 170 peer-reviewed scientific papers and in 2011 he published a widely-acclaimed book on the life histories of Pacific Northwest butterflies which renowned British naturalist David Attenborough called ‘Magisterial’. Currently, he is working on sustainability of IPM and conservation biological control in viticulture, insect conservation and community research and education projects with Washington grape growers, Washington State Penitentiary and Cowiche Canyon Conservancy.
