Roger A. Morse, Ph.D. (July 5, 1927 - May 12, 2000) was a bee biologist who taught many beekeepers both the rudiments and the finer practices, through his research and publications. During his long career, three new parasites of the honeybee, acarine mite, varroa mite and African small hive beetle were introduced to the USA. These, along with the Africanized honeybee and pesticide kills were all important beekeeping issues. Morse was extensively involved in research on each of these and provided guidance to the beekeeping industry.
