In the past, the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans.
[7] Early entomological works associated with the naming and classification of species followed the practice of maintaining cabinets of curiosity, predominantly in Europe.
In the late 19th century, the growth of agriculture, and colonial trade spawned the "era of economic entomology" which created the professional entomologist associated with the rise of the university and training in the field of biology.
This has led to the development of automated species identification systems targeted on insects, for example, Daisy, ABIS, SPIDA and Draw-wing.
In 1994, the Entomological Society of America launched a new professional certification program for the pest control industry called the Associate Certified Entomologist (ACE).
To be qualified in public health entomology (PHE), one must pass an exam on the types of arthropods that can spread diseases and lead to medical complications (ESA Certification Corporation).
Individuals who are planning to become Certified IPM Technicians (CITs), need to obtain at around 1-4 years of experience in pest management and successfully pass an exam, that is based on the information, that they are acquainted with (ESA Certification Corporation).
Like in Public Health Entomology (PHE), those who want to become Certified IPM Technicians (CITs) also have to "agree to ascribe to a code of ethical behavior" (ESA Certification Corporation).
For those who plan on becoming Board Certified Entomologists (BCEs), individuals have to pass two exams and "agree to ascribe to a code of ethical behavior" (ESA Certification Corporation).
Veterinary entomology is included in this category, because many animal diseases can "jump species" and become a human health threat, for example, bovine encephalitis.
