Entomology is the scientific study of insects. It is a branch of zoology that focuses on the behavior, structure, physiology, classification, and distribution of insects. Entomologists are scientists who specialize in the study of insects and their relationship to humans, the environment, and other organisms. Entomology covers a wide range of topics, from the study of the anatomy and physiology of insects to the study of their ecology and evolution. Entomology also includes the study of insect-borne diseases, pest management, and the use of insects in biotechnology.
