I have the distinction of being the only ENTOMOLOGY faculty member not located on the main campus in Lexington. Click here for a Brief Biography and here for a Brief Vitaor(Vita in pdf format). Myself and Ms. Patty Lucas, who assists me with the IPM program, are located in Princeton, KY at the Research and Education Center. This education and research facility is located on 1200 acres in the western third of the state where about 80% of Kentucky's field crops are produced.

The overall objective of my program is to provide the citizens of Kentucky with the most reliable and modern information, educational opportunities and decision devices available as they relate to entomology and related concepts. I use many techniques to extend important information. However, you might find that receiving Kentucky Pest News or using our series of ENTFACTS very useful and easy to access. Much of my time and effort is applied to the teaching and development of Integrated Pest Management (IPM) concepts. This philosophy teaches the use of all available methods to manage not eradicate pest while avoiding economic and environmental problems. Closely allied with this concept is the Pesticide Safety Education program which concentrates on the proper and safe use of pesticides. Within our Entomology extension group, I have lead responsibility for soybean, grain sorghum, small grains, and stored grain.

My current interests in applied research revolves around insects as vectors of field crop pathogens, and the tools (new and used!) used to manage the situations. There are currently two areas of work. The wheat - grain aphid - barley yellow dwarf virus system is a long standing problem for Kentucky grown small grains. The soybean - bean leaf beetle - bean pod mottle virus system, a long standing but relatively small problem has become very important with the introduction of the Soybean Aphid . This aphid may vector several viruses, each important in soybean, but greatly magnified when in mixed infections with bean pod mottle virus.

The interest of Kentucky's wheat producers in Intensive Wheat Management make this complex a very important consideration. Much of my work is done in conjunction with the Wheat Science Working Group. As part of my efforts in this area of research and education I am privileged to organize a symposium on BYDV at the 1999 Annual Meeting of the Entomological Society of America. Click to see an outline of the program. Look here for a quick overview of how I think BYD develops in Kentucky.

Bean leaf beetle on soybean leaf Soybean - Bean Leaf Beetle / Soybean Aphid - Soybean Virus Complex. The bean leaf beetle has long been a potential problem in Kentucky grown soybeans for its early season damage to seedlings, then again late in the season for to feeding directly on pods. It addition the beetles ability to vector the bean pod mottle virus is problematic on occasion. However, the introduction in 2000 of the soybean aphid, has opened a new chapter on the soybean insect - plant pathogen - host system. With the introduction of the soybean aphid comes an new insect pest, an insect that can vector several soybean damaging viruses, and the possibility of mixed viral infections. Some of which are much more dangerous that each individual virus separately. Soybean aphid courtesy of University of Nebraska


I spend a great deal of time in the class rooms and on tours with Primary and Secondary school students. Most of these efforts are directed at introducing sometimes reluctant students to the world of insects, spiders and other related arthropods. Additionally, I like to work in the concepts of IPM as ‘THE' method of pest control that provides management for pests and protection for the environment.

PERSONAL-- Biking - I'm a two to three thousand miles a year man. Not particularly fast, but I enjoy the weekly after work rides, and the occasional weekend tour with my friends.

Family History - Both my wife and myself are involved in tracing the history of our families. Not fanatical in our zeal but relatively steady and thorough. If you are Johns(t)on(e), Pool(e), Tall(e)y or Fox, from North or South Carolina or Virginia I need to hear from you! You may reach me at:
