What is Entomology?

Entomology is the branch of zoology, which is mainly involved with the study of insects, their characteristics, general anatomy, morphology, and its contributions to biological diversity and a variety of other fields of science. Scientists who study insects, their structure, different parts, along with their functions and other features are called Entomologists. William Kirby is called the father of entomology based on his contributions to the field of the Study.

Professional entomologists contribute to the betterment of humankind by detecting the role of insects in the spread of disease and discovering ways of protecting food and fiber crops, and livestock from being damaged. They study the way beneficial insects contribute to the well being of humans, animals, and plants. Amateur entomologists are interested in insects because of the beauty and diversity of these creatures.Entomology- study of-Insects-examples

Significance Of Entomology

Entomology mainly deals with the scientific study of insects. Entomology is derived from the Greek word- Entomon meaning notched, also referred to as the body segments found in all insects. The study of Entomology also deals with the study of the relationship between insects, humans, food, biological diversity, pharmaceuticals, our environment, and other fields of science.


Apart from studying the anatomy and physiology of insects, Entomology is widely used in many other disciplines, including evolutionary biology, medical research, in agricultural entomologists to protect the valuable resources from insect pests and also in the studies of biodiversity. This is the area concerned with physiological and population processes.

  • Environmental Science: Insects are a vital part of forest biodiversity and they are particularly sensitive to changes in the climate and the patterns and seasons of regional flora cover. Here entomology provides evidence for general forest health, effects of deforestation, continuous ecological issues such as flooding and drought. They can tell us much about the types of trees, shrubs, and flowers that grow there and also play a significant role in the pollination process.
  • Forensic Entomology: It is the scientific study of the invasion of the succession pattern of arthropods with their developmental stages of different species found on the decomposed cadavers during legal investigations. It is the application and study of insect and other arthropod biology to criminal matters. It also involves the application of the study of arthropods, including insects, arachnids, centipedes, millipedes, and crustaceans to criminal or legal cases. It is primarily associated with death investigations; however, it may also be used to detect drugs and poisons, determine the location of an incident, and find the presence and time of the infliction of wounds. Forensic entomology can be divided into three subfields: urban, stored-product, and medico-legal/medico-criminal entomology.
