The term for the study of insects is entomology. This branch of zoology focuses primarily on the classification, behavior, ecology, and physiology of insects. Insects are the most diverse group of organisms on Earth, comprising over a million described species. Entomologists study various aspects of insects, including their role in ecosystems, their interactions with humans (both beneficial and detrimental), and their potential usefulness in agriculture or pest control. The insights gained from entomology can also have significant implications in fields such as medicine, environmental science, and climate change research.
