The term for a person who studies insects is "entomologist." Entomology is a specialized branch of zoology focused on the classification, behavior, ecology, and physiology of insects. Entomologists play a crucial role in agriculture, medicine, and environmental science by studying insects that impact crops, spread diseases, and contribute to ecosystems, such as pollinators. Their work involves field studies, laboratory experiments, and the development of pest control strategies. Understanding insect biology helps improve biodiversity conservation and sustainable agricultural practices.
