About Entomology & Plant Pathology

What is Entomology?

Entomology is the discipline of insect science and is a biological science curriculum that uses insects as models to illustrate science concepts.

What does entomology involve?

Entomology involves everything from "outdoor" work in environmental issues (invasive species, emerging arthropod-borne disease), ecology, animal behavior, parasitology, insect-plant interactions to very "high tech" applications in biotechnology, molecular studies, forensics, and medical/veterinary entomology.

What is Plant Pathology?

Plant pathology is the study of the cause, forecast, spread, genetics, and management of plant diseases, and encompasses many if not all plants of economic importance including crops, trees, and horticultural/ornamental plants.

What does plant pathology involve?

Plant pathology uses knowledge, techniques, and expertise from a multitude of disciplines such as mycology, virology, bacteriology, nematology, biochemistry, bioinformatics, plant anatomy, plant physiology, genetics, microbial forensics, and epidemiology to study, understand, and manage plant diseases.
