Entomologists can work in a variety of settings: classroom, laboratory, greenhouse, agricultural field, or urban setting. Many entomologists do a degree of pure research, either via an academic affiliation, museum, or government agency, which usually includes some teaching duties as well.
Entomologists can also work for private companies in the fields of pest management, crop science, or pharmaceuticals. They can work with microbiologists, toxicologists, and pharmacologists to come up with novel drugs (eg. based on bee venom) or ways to combat existing crop diseases.
Entomologists also find work in the law enforcement field, working with pathologists or crime scene analysts to detect drugs and poisons, determine the location of an incident, and find the presence and time of the infliction of wounds.
Entomologists can also work in the laboratory doing genetic analysis of agriculturally important pests, breeding engineered insects for biological control, or basic physiological research.
A degree in entomology can be used for entry to medicine or law, or further studies in animal science or zoology.
