Entomology is the study of insects and their relationship to humans, the environment, and other organisms. Entomologists make great contributions to such diverse fields as agriculture, chemistry, biology, human/animal health, molecular science, criminology, and forensics. The study of insects serves as the basis for developments in biological and chemical pest control, food and fiber production and storage, pharmaceuticals epidemiology, biological diversity, and a variety of other fields of science.

Entomology is an ancient science, dating back to the establishment of biology as a formal field of study by Aristotle (384-322 BC). There are even earlier references to the use of insects in daily life: such as the growing of silkworms that began 4700 BC in China, which was an important part of peasant life in China, as early as 4000 BC. More than a hundred years ago, entomologists formed a society, the Entomological Society of America (ESA), to promote the science and study of entomology in the United States.
