Diana Sammataro, co-author of the Beekeeper’s Handbook (4th ed. 2011), began keeping bees in 1972 in Litchfield, CT, setting up a colony in her maternal grandfather’s old bee hive equipment. From then on, she decided that her B.S. in Landscape Architecture (Un. of Michigan, Ann Arbor), would not be a career, but that honey bees would. After a year of independent studies on floral pollination (Michigan State Un. Bee Lab, East Lansing), she earned an M.S. in Urban Forestry (Un. Michigan, Ann Arbor). In 1978 she joined Peace Corps and taught beekeeping in the Philippines for 3 years. On returning, she worked at the USDA Bee Lab in Madison, WI under Dr. Eric Erickson, studying the effects of plant breeding and flower attraction of bees in sunflower lines. When the lab closed, she eventually went to work at the A.I. Root Company as Bee Supply Sales Manager in Medina OH. In 1991 she was accepted at the Rothenbuhler Honey Bee Lab at The Ohio State University (Columbus, OH) to study for a Ph.D. under Drs. Brian Smith and Glen Needham. In 1995, she worked as a post-doctoral assistant at the Ohio State University Ag. Research Center in Wooster OH, with Dr. James Tew and in 1998 at the Penn State University Bee lab, (State College, PA) with Maryann Frazier and Dr. Nancy Ostiguy. Early in 2002, she was invited to join the USDA-ARS Carl Hayden Honey Bee Research Center in Tucson AZ. Her current position is a Research Entomologist with Dr. G. DeGrandi-Hoffman and staff. Her current work at the lab includes research on bee nutrition problems, Varroa, proteomics of bees and mites, and pollination problems. Her current goal is to do more extension work and teaching, and to expand and share her knowledge on a broader arena, as well as to foster and promote understanding that all pollinating species are important to human health and survival.

ABSTRACT of Dissertation

Title: Studies on the control, behavior, and molecular markers of the tracheal mite (Acarapis woodi (Rennie)) of honey bees (Hymenoptera: Apidae).

Abstract: The endoparasitic mite, A. woodi (Rennie), a pest of honey bees Apis mellifera L., infests most bee colonies in the United States and has been responsible for 60% of colony losses. Under field conditions, patties made from solid vegetable shortening and white sugar, with or without the addition of an antibiotic, depressed mite populations when applied continuously to bees. Treatment was significant (Site 1, F2,165=14.95; P<0.001; Site 2, F2,96=5.541; P<0.001). To understand why shortening/sugar patties gave bees some protection, mite behavior was videotaped on callow bees (<4 days old), dead bees and bees exposed to an oil patty. Two behaviors were observed and more closely studied. “Habitat-seeking” behavior, when mites seek out a new oviposition site, was disrupted on both dead and oil-treated bees. “Questing” behavior, associated with mite transfer between hosts, increased on dead and oily bees. Both questing (F2,66 =7.88; P<0.001) and habitat-seeking (F2,66=21.28, P<0.001) behaviors were significantly different between all three treatments. Oil-treated bees gained protection from habitat-seeking mites because the normal behavior of the mites is interrupted. Questing behavior increased significantly on dead and oily bees, thus exposing the mites for a longer time and increasing the chances of desiccation. In the decade since its introduction here, the lethal effects of this mite seem to diminish. To determine if this was a change in the lethality of mite populations, infested bees from several states were collected and the mites dissected. RAPDs was used to track possible shifts in genetic markers. Problems of reaction protocols, contamination and clean negative controls were mostly solved by using HPLC water that was not treated to UV light. PCR parameters where annealing temperatures ranged from 38-45C also produced good results. However, because of extremely low mite DNA concentrations, the results were inconclusive. By testing a dilution series using one bee, it was found that as the concentration of DNA diminished to 0.038ng/ul, more bands in the gel appeared. RAPDs was not a good method of choice; this question still needs to be explored as future techniques are refined.
