Entomologists are scientists who specialize in the study of insects. They are also known as insect studiers, and their field of study is called entomology. Entomologists research the behavior, physiology, ecology, and evolution of insects, as well as their interactions with other organisms and the environment. They also work to develop methods for controlling insect populations, such as pest control. Entomologists may also be involved in teaching, public outreach, and policy development.
