Which term is the study of insects?

• A. Entomology
• B. Agronomy
• C. Horticulture
• D. Aquaculture

Answer: (A)

Studying insects is entomology—the branch of zoology that investigates the biology, classification, and behavior of insects, along with their roles in ecosystems and impacts on humans. Entomology covers insect anatomy, life cycles, ecology, taxonomy, and applied areas like pest management and pollination biology. The other terms refer to different fields: agronomy focuses on crop production and soil management, horticulture deals with growing and caring for plants, and aquaculture involves farming aquatic organisms. So entomology is the term that specifically describes the study of insects.
