The Department of Entomology and Nematology offers the Master of Agriculture, Master of Science, and Doc- tor of Philosophy degrees in entomology and nematol- ogy. Members of the graduate faculty include the depart- mental resident faculty, faculty located on University of Florida campuses away from Gainesville, scientists of the U.S. Department of Agriculture, and scientists with other State of Florida agencies such as the Division of Plant Industry, Florida State Department of Agriculture and Consumer Service. The graduate faculty is qualified to direct graduate students in all specialties of entomology, nematology; and acarology. New graduate students should have backgrounds in biology, chemistry, physics, and mathematics and knowledge of basic entomology or nematology. Minor deficiencies may be made up after entering graduate school. General requirements for graduate degrees are established by the Graduate School, and listed elsewhere in this Catalog. A specific program of study is prepared by the appointed supervisory committee for each stu- dent. Ph.D. qualifying examinations are administered on campus by the student's supervisory committee plus two other faculty members appointed by the chairman of the department.
