For undergraduate curriculum in entomology, see College of Agriculture, Curricula.
The undergraduate curriculum in entomology is designed for persons interested in studying insects, their adaptations, and the practicalities of dealing with them. Students electing entomology as a major will prepare themselves for positions in industry, business, government, education, and public health. Graduates may acquire positions in research, development, and technical sales for agricultural chemical and seed companies. State and federal agencies employ entomologists as consultants, extension directors, mosquito abatement agents, inspectors, and research aides. Entomologists may also find employment with urban or agricultural pest-management or consulting firms, large private farms and ranches, and horticultural nurseries.
All graduates understand the principles of insect structure and function. They understand the evolutionary and ecological relationships of insects with other life forms, and the impact of insects relative to human and animal health, as well as the relationships between insects and humanity's food, fiber, structural, and aesthetic needs and expectations. Graduates understand the principles and methods available to manage beneficial and pest insect populations. They are skilled in identifying insects and related groups and understand the biology, ecology, behavior, diversity, and evolutionary relationships of the major groups of insects. They understand the application of the scientific method in problem solving and the principles of experimental design and analysis. Graduates are able to communicate research and educational materials properly and competently - orally, visually, and in writing - and are able to work effectively with others.
Graduates of the agricultural and horticultural insect management option are skilled in determining pest levels and impact on plant and animal hosts, and the management of these pests. They understand the environmental, legal, and ethical issues involved in insect population management.
Graduates of the insect biology option have achieved an understanding of the biochemical and physiological processes governing insect metabolism, growth, and form. They understand the evolutionary and ecological significance of insects. They also have a broad background in the biological sciences. Assuming good academic performance, graduates of this option are prepared to enter graduate or professional schools.
Entomology participates in the interdepartmental undergraduate majors in integrated pest management, and the emerging global diseases minor.
The department offers a minor in entomology that may be earned by completing 370, 374, 376, and 6 credits in courses selected from an approved list supplied by the department.
A preveterinary program is available in entomology.
The department offers work for the degrees master of science and doctor of philosophy with a major in entomology or toxicology. Within the entomology major, the student may concentrate in aquatic entomology, biological control, chemical ecology, genetics, forest entomology, host plant resistance, medical/veterinary entomology, morphology, pathology, pest management, physiology, population ecology/genetics, systematics, or insecticide toxicology.
Graduates have a broad understanding of entomology and related disciplines, and an in-depth command of their area of concentration. They are able to communicate effectively with scientific colleagues and the general public in both formal and informal settings. Graduates are able to address complex problems facing entomology or toxicology professionals, taking into account related ethical, social, legal, economic, and environmental issues. They are skilled in research methods, data analyses, and interpretation of results. They also are skilled in working effectively with their colleagues, and writing concise and persuasive grant proposals. They have an understanding of and can critically evaluate current entomological literature. Prerequisite to the entomology major and to minor graduate work in the department is completion of at least two years of zoological courses, for part of which credit in other closely allied biological sciences may be substituted. Specific course requirements for advanced degrees depend partly upon previous training and experience in the major field of specialization.
Any student receiving the M.S. in entomology shall have at least one course in insect physiology, one course in insect systematics, two courses of Ent 590 (selected from topics A through D, F through I, M and N, inclusive), and at least 1 credit of Ent 600. Any student receiving the Ph.D. in entomology shall have at least one course in insect physiology, one course in insect systematics, four additional courses of Ent 590 (selected from topics A through D and F through I, L through N inclusive), and at least 1 credit of Ent 600. In addition, Ph.D. students majoring either in Entomology or Toxicology shall have two semesters of teaching experience, taken as Ent 590K both semesters or Ent 590K one semester and Ent 590L the other semester.
Entomology participates in the interdepartmental majors in ecology and evolutionary biology; genetics; and molecular, cellular and developmental biology; and in the interdepartmental major and minor in toxicology (see Index).
The Federal Corn Insects and Crop Genetics Research Unit and the North Central Plant Introduction Station are available for advanced study in certain phases of entomological research.
More information about the department, such as current research, faculty resumes, physical facilities, and graduate students can be viewed on the department's world-wide web page.
