Entomology and Plant Pathology Website

The Department of Entomology and Plant Pathology offers three undergraduate minors:

  • Entomology
  • Plant Pathology
  • As well as an interdisciplinary Pest Management minor.

Full degree programs are offered only at the graduate level.

Entomology is the branch of science concerned with the study of insects and related organisms. It involves studies of their biology, structure, identification, economic significance, and population management. The major emphasis of the curriculum is understanding insect biology and applying that knowledge in an integrated approach to insect-pest management.

Plant pathology is the study of interrelationships of plants with the abiotic and biotic agents that affect plant health and productivity. The goal of the discipline is to minimize the impact of plant diseases on agricultural production and human health. Scientific training within the department focuses on the nature, cause, and management of plant diseases.

Undergraduate students interested in graduate work in entomology or plant pathology should pursue one of the minors here or the Pest Management minor.
