The study of insects is called entomology. This branch of zoology focuses on the classification, behavior, ecology, physiology, and management of insects. Entomologists play a critical role in various fields, such as agriculture, medicine, and environmental science, as insects can impact ecosystems, pollination, and pest control. With over a million described species, insects represent the most diverse group of organisms on the planet, making their study essential for understanding biodiversity and ecological health. Entomology helps address crucial issues, like agricultural pest management and the spread of vector-borne diseases, contributing significantly to human knowledge and welfare.
