The department offers programs leading to the Master of Science and Doctor of Philosophy degrees with a major in entomology. Faculty interests include insect behavior, ecology, evolution, physiology, and systematics; integrated pest management; aquatic entomology; biochemical toxicology; biological control; chemical ecology; pesticide use information; resistance management; social insect biology and urban entomology. Research opportunities with insects also exist in the departments of Biochemistry, Ecology and Evolutionary Biology, the Committee on Neuroscience, and the Program in Insect Science. The Center for Insect Science provides opportunities for collaborative research with a large group of insect scientists in the state. Facilities for field studies include University Agricultural Centers in Maricopa (MAC) and Yuma (YAC) and a farm with an entomology lab 3 miles from campus. Four faculty members are stationed off-campus: Peter C. Ellsworth (MAC), Dawn H. Gouge (MAC),  and John C. Palumbo (YAC). Natural habitats can be studied on University land in the Sonoran Desert and in the rangelands and canyons of the Santa Rita Mountains. Several excellent field centers are available in the diverse biomes of Southern Arizona.

Admission requirements include the completion of an undergraduate major in the biological sciences. The undergraduate program should include course work in physics, organic chemistry, mathematics, and the evolutionary, ecological, organismic, cellular, and molecular aspects of biology. Applicants must submit official transcripts, scores on the general tests of the Graduate Record Examination, the Test of English as a Foreign Language when applicable, letters of recommendation from persons in a position to assess the applicant's potential as a graduate student, and other documents pertinent to the department. 

Graduate study programs are individually planned and approved by the student's committee. Candidates for the Master's degree in entomology will be required to take two units of seminar and two courses selected from ENTO 507, 511, 515, 516, and 544. A thesis is required. Candidates for the Master's degree with a concentration in applied entomology can specialize in agricultural entomology, urban entomology, or medical and veterinary entomology. Course requirements are ENTO 516, 544 and three courses selected from the area of specialization. A non-thesis option is available. The doctoral program requires four units of seminar and three courses selected from ENTO 507, 511, 515, 516 and 544, plus six credits from upper-division courses offered by the Department of Entomology.
