What is the primary focus of entomology?

Entomology is primarily concerned with the study of insects, which encompasses their biology, behavior, ecology, taxonomy, and the roles they play in ecosystems. This field of study is vital because insects represent the most diverse group of organisms on Earth, contributing significantly to ecological balance through pollination, decomposition, and serving as food for other species. Understanding their physiology and life cycles can also help address agricultural challenges, pest management, and biodiversity conservation.

The other disciplines mentioned are related to different branches of biology; for example, the classification of plants pertains to botany, while investigations of mammals and research on amphibians relate to mammalogy and herpetology, respectively. Each of these fields has its specific focus, but they do not overlap with the core focus on insects that defines entomology.
