The entomology it is the branch of the zoology focused on insect study . To understand the concept accurately, in this framework, one must first define what zoology is and what insects are.
Is called zoology to science what analyze the animals . A insect , meanwhile, it is a type of animal: a arthropod (A class of invertebrate ) which has three pairs of legs and one of antennas, has one or two pairs of wings and has a segmented body in the abdomen, thorax and head.
From these ideas , we can affirm that the entomology is a scientific discipline whose object of study are insects , which belong to the animal kingdom. The entomology expert is known as entomologist .
It is believed that insects appeared 400 million years , in the Paleozoic Era . The farthest roots of entomology must be found in the prehistory , since the human being was always interested in knowing more about these species due to their incidence in crops.
From XIX century , the observations on the insects acquired greater formality and rigor and thus the entomology was forged. Own Charles Darwin (1809-1882), who postulated the natural selection as a mechanism of biological evolution , entered the entomology.
When studies of these animals are carried out based on their own human interest, they talk about applied entomology . This area includes the work carried out to generate knowledge about the control of pests , the disease transmission and the wax and honey production , for example. The forensic entomology On the other hand, it is the specialty that focuses on insects installed in a corpse to estimate the date of death of the individual.
