Benson Cambodia

Dr. Eric Benson, is a professor of entomology specializing in integrated pest management and training programs at Clemson University. Dr. Benson also teaches general entomology and for over ten years, has hosted a live, call-in program on public radio where listeners can call to ask questions about insects and related arthropods. Beyond the Southeast Asia IPMCRSP project, Dr. Benson has research projects on ants, termites, bed bugs and cockroaches.

Guido Schnabel1Guido Schnabel received his Ph.D. in plant pathology from the University of Hohenheim in Stuttgart, Germany in 1997. Schnabel was a post-doctoral research associate at Michigan State University before beginning his position in 2000 as the fruit pathologist at Clemson University. His research focuses on integrated management of diseases affecting peach and strawberry, including brown rot, Armillaria root rot, peach scab, gray mold, Anthracnose, and other summer diseases.  Current projects are: (i) Characterization, identification, and molecular basis of fungicide resistance in Monilinia fructicola and Botrytis cinerea; (ii) development of transgenic rootstocks exhibiting disease and nematode resistance; (iii) investigation of biocontrol agents (Trichoderma species), root collar excavation, and fungicide injections for Armillaria root rot control.  His extension program focuses on (i) educating commercial growers and county agents on the biology, epidemiology, and management of diseases of fruit crops; (ii) providing tools for effective disease management; such as precision brown rot management to generate location-specific fungicide resistance profiles using the Profile monitoring kit; and (iv) providing up-to-date information via the website

Merlene In DominicaB. Merle Shepard, Ph.D., Vice President, Lowcountry Biodiversity Foundation

He is professor emeritus of entomology with Clemson University’s Coastal Research and Education Center in Charleston, South Carolina. His vast international experiences includes five years as Head of Entomology Department, International Rice Research Institute, in the Philippines, Project Director for an integrated pest management project in Indonesia where he lived for three years, a one-year sabbatical at the University of Queensland, Australia. His research focuses on integrated pest management and biological control of insect, with emphasis strategies that avoid the use of chemical insecticides. His field guide entitled “Friends of the Rice Farmer: Helpful Insects, Spiders, and Pathogens” has been translated into over 25 non-English languages with over 100,000 copies printed.Along  with Dr. Ed Farnworth and Mr.Keith McCullough, Shepard published “Common Insects and Spiders o f the South Carolina Lowcountry in 2011. The awards that he has received include the Entomological Society of America’s Award for Excellence in Pest Management in 1998.
