  • Professor
  • Fruit Entomologist

General

My position (40% teaching, 35% research, 25% extension) deals primarily with fruit IPM and ecological interactions in vineyard, small fruit, and orchard systems.  I teach undergraduate and graduate courses in Integrated Pest Management, as well as Insect Structure and Function.

Education

B.S. (1976), University of Massachusetts 

M.S. (1978), North Carolina State University 

Ph.D. (1982), Washington State University

Professional Memberships

Courses Taught

I am an instructor in the online Masters of Agriculture and Life Sciences degree program.  (See 2014-2015 Extended Campus tuition rates) (Presenting the OMALS program in a distance learning symposium in Dakar Senegal)

I have developed an international component to my program, and am involved in two regional projects.  Within IPM IL (Integrated Pest Management Innovation Lab, supported by USAID), I work with biological control in rice.  In another project (ERA – Education and Research in Agriculture, also supported by USAID), I work on development of distance learning, and management of an invasive fruit fly, Bactrocera dorsalis in mango (see a posting in The Compass blog on a student project on fruit flies attacking mango).  I was formerly the Site Chair for the Eastern European and West African regional projects (Albania, Ukraine and Moldova) within the IPM IL (formerly IPM CRSP). These projects deal with high value horticultural crops, primarily vegetable crops.

My overall research program deals with Integrated Pest Management in Vineyard, Small Fruit, and Orchard systems.  Currently two species comprise most of my Virginia fruit IPM research - conventional and organic management of brown marmorated stink bug, and spotted wing drosophila.  In recent years, other research has centered in mating disruption for lepidopteran pests, grape root borer, Japanese beetle in caneberry and vineyard settings, and sharpshooters that transmit Pierce's disease in grapevines, biogeography of plum curculio strains and their Wolbachia symbionts, and insect/plant interactions.  I also have an international research program, dealing with IPM in mango (Senegal) and rice (Cambodia).

Projects

  • Ecological interactions between spotted wing drosophila and African fig fly
  • Potential for biological control of spotted wing drosophila
  • Biology, ecology, and management of brown marmorated stink bug in orchard crops
  • Biological control in Cambodian rice production
  • Biology and management of oriental fruit fly in Senegalese mango
  • Invasive ant distribution in Hawaii

I maintain an active extension program in vineyard, small fruit and orchard IPM.  We hold winter educational meetings, as well as field meetings for growers in the spring and summer.  I participate in written extension publications, e-mail updates and web sites to distribute extension information.
