Extension Program

• Provide extension personnel, farmers, agribusiness, and industry clientele with complete, comprehensible educational programs including control recommendations, decision guidelines and information relating to field identification, biology and management alternatives for arthropods associated with alfalfa, tobacco, livestock, and biological control of nodding thistle. Much of this information is made available through the Kentucky Pest News.
• Coordinate and conduct Pesticide Applicator Training programs for private and commercial applicators. This includes development of educational meetings, and training manuals, and aids for initial and continuing certification programs.
• Participate in and contribute to Kentucky's Multi-Disciplinary, Multi-Crop Pest Management Program by providing training materials, conducting on-the-job training for field scouts and to interpret information collected by the program. Activities in this area also contribute to the Certified Crop Advisor program in Kentucky.
• Conduct demonstrations and applied research trials that provide both quantitative and qualitative information regarding pest management techniques as appropriate.
• Insect Indentification Service- This includes making identifications, recommendations, and maintaining the computer data base of identification data which is used in program planning. Approximately 1,000 specimens are processed each year.

• CRP Land and Soil Insect Pests In Factors to consider when bringing conservation reserve program (CRP) land or idle land back into production. ID-124
• A comprehensive guide to wheat management in Kentucky. Co-wrote the wheat insect section and contributed to the BYD virus section of plant pathology. ID-125

Applied Research Program

• Applied field research provides the basis for most of my extension programs. Major emphasis is placed upon tobacco because of its value to the Commonwealth and the lack of applicable research information from other states. For the last several years, work has focused upon the tobacco aphid, an insect that can cause serious yield losses in any field in the state. A 2-year grant from the Council for Burley Tobacco has supported a graduate student to evaluate the cultural practice of double-barning along with preventive and rescue approaches to tobacco aphid control. Effects of the aphid control strategy on yield, quality, and beneficial species were included. The Council grant has allowed a much more in-depth approach to aphid management than otherwise would have been possible. The tobacco budworm is a chronic pest in some parts of Kentucky. The ability to work with artificial field infestations of this insect in field plots has provided information on budworm management options.
• The thistle weevil program continues to function mainly due to efforts by the CAPS summer survey program. There is a much clearer picture of the distribution of the thistlehead weevil. A cooperative program in 1997 with the Military Affairs office of the Kentucky National Guard has resulted in establishment of populations at the West Kentucky Training facility. Personnel there are incorporating the weevil into their management program. Peabody Coal and the Ky Division of Wildlife Management worked in 1997-98 to spread the weevil on strip mine reclamation areas in Muhlenberg and Ohio counties.
• A pheromone trapping program was initiated in 1999 to invetigate the sawfly complex that attacks Christmas tree plantings in Kentucky.
