Dr. Keith Delaplane


The stated objectives of the honey bee program at the University of Georgia are to increase knowledge in bee biology, management, and crop pollination and to deliver that knowledge in the most effective manner to interested users. A related goal is to train undergraduate and graduate students in practical beekeeping, bee biology, and the scientific methods of critical thinking and analysis. Prospective graduate students are encouraged to subscribe to these objectives.

The program is heavily weighted toward problems in applied apiculture and pollination. However, basic research is also encouraged as it is basic research that precedes and underpins more applied discoveries.

All students, whether engaged in basic or applied problems, are expected to participate in any number of the beekeeper-oriented workshops, lectures, and meetings conducted by the program. Authorship in extension publications, videos, bulletins, and popular articles is also encouraged. This type of clientele contact is considered a valuable part of the student's education and serves to improve the student's competitiveness in the entomology job market.

Although any aspect of bee biology and plant pollination is open to consideration for thesis or dissertation projects, some of the more recent research areas in the program include: pathological effects of parasitic mites on honey bees, integrated control of parasitic mites, interaction of comb substrate on bee sociobiology, blueberry pollination, flower behavior of blueberry pollinators, and bee conservation biology.
