Entomology

Entomology from Greek word : entomos means insect; and logia means study is the scientific study of insects.
At some 1.3 million described species, insects accounts for more than two-thirds of all known organisms, date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth.
It is a specialty within the field of Biology, though technically incorrect, the definition is sometimes widened to include the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, and slugs.
Like several of that are categorized within zoology, entomology, is a taxon-based category; any form of scientific study in which the organism studies happen to be insects is, by definition, entomology as well.
Entomology therefore includes a cross-section of topics as diverse as:
• molecular genetics,
• behavior,
• biomechanics,
• biochemistry,
• systematic,
• physiology,
• developmental biology,
• ecology,
• morphology
• paleontology
• anthropology
• robotics
• agriculture
• nutrition
