Entomology, a term that derives from the Greek: ἔντομον «insect», and λογία- «study of», is a branch of zoology dedicated to the study of insects, including also the primitive forms of the hexapods.
Entomology can be divided into two sections:
General entomology, which studies insects in a broad sense in their various scientific aspects: morphology, anatomy, physiology, behavior, phylogeny, ecology, etc.
Applied entomology, which studies insects in specific operational or applicative contexts, also establishing close relationships with various branches of technological sciences.
The importance of entomology is linked to the fact that insects are the largest and most diverse group of organisms on Earth, with over a million species described and many more yet to be discovered. Entomology focuses on understanding the morphology, physiology, taxonomy, ecology, behavior, and evolution of insects.
Entomologists are scientists who study insects and can work in a variety of fields, including agriculture, medicine, conservation research, natural resource management, toxicology, and many others. This discipline is fundamental for understanding the role of insects in ecosystems, the interaction of insects with humans, agriculture and ecology, as well as for tackling problems such as pest infestations for agricultural crops and as vectors of diseases for public health.
Entomology is a very diverse and fascinating science that has a significant impact on various aspects of human life and the environment.

History –
The history of entomology dates back thousands of years, with roots in ancient civilizations and cultures around the world.
Insects have been observed and studied by many ancient civilizations, including Ancient Egypt and China. The ancient Egyptians engraved depictions of insects on tombs and artifacts, while the ancient Chinese documented insects in their literary and medicinal works.
Aristotle, one of Ancient Greece’s most influential philosophers, is often considered one of the first entomologists. In his work «History of Animals», Aristotle classified and described numerous insects and studied them from a morphological and behavioral point of view.
During the Renaissance, interest in the natural sciences, including entomology, revived in Europe. Leonardo da Vinci’s work included detailed observations of insects, and artists such as Albrecht Dürer created illustrations of insects.
In the 17th century, Dutch naturalist Jan Swammerdam made major contributions to entomology through his work on insect morphology and development. In the 18th century, Carl Linnaeus introduced a taxonomic classification system that revolutionized the study of insects and biodiversity in general.
The 19th century saw a significant growth in entomology with the work of entomologists such as Jean-Henri Fabre, who conducted extensive behavioral studies of insects, and Charles Darwin, who factored the evolution of insects into his theories of evolution.
In the 20th century, entomology continued to develop with major contributions in research on insects as biological control agents, toxicology, and insect genetics. The use of modern techniques such as molecular genetics has further advanced our understanding of insects.
Today, entomology is a diverse discipline that covers a wide range of topics, from taxonomy and morphology to molecular biology and ecology. Entomologists play a vital role in our understanding of insects and their impacts on ecosystems, agriculture, medicine and many other areas.
