The term for the scientific study of insects is entomology. This branch of zoology focuses on the behavior, ecology, physiology, and taxonomy of insects, which make up a significant portion of Earth's biodiversity. Entomologists play a crucial role in various fields, including agriculture, medicine, and environmental science, as they study insects' interactions with ecosystems, their roles as pollinators, and their impact as pests or disease carriers. Their research is vital for pest management strategies and understanding ecological balance, contributing to both scientific knowledge and practical applications in various industries.
