Entomology is the scientific study of insects. Insects have a great influence on the state of our environment, especially on the availability of food and the control of disease.

Harmful insects lead to the destruction of crops in the field or stored food and they spread diseases from animals to human beings. Useful insects are responsible for the control of harmful insects and weeds, as well as the cross-pollination of crops.

Through the study of the anatomy, life processes, habits and life cycles of insects, the entomologist distinguishes between harmful and useful insects. Using this information, entomologists can develop suitable and economically viable measures of control against harmful insects. Entomologists are also responsible for the registration, standardisation and testing of insecticides.

Entomologists try to ensure that useful insects are not destroyed. Much attention is given to the increasing use of certain beneficial insects for the biological control of harmful insects and of weeds. Today, entomologists focus their research on "effective pest management" where the environment is also taken into account, rather than "pest control" which only focused on controlling pests regardless of damage caused to the environment.

New fields of research for entomologists include the use of insects for monitoring damage, pollution and the recovery of the environment through recording the insects. Entomologists are responsible for the identification and classification of insects. Knowledge regarding insects is gained through fieldwork as well as laboratory research.

Entomologists often do research work or are employed as extension officers and consultants in a variety of fields.

Some areas of specialization include:

- conducting detailed studies of insects and their behaviour
- taxonomy, which entails the classification and documentation of insect fauna
- use of beneficial insects
- biological control of harmful insects
- integrated pest management
- veterinary and medical entomology

As consultants, entomologists render a service to a wide range of people, including farmers, environmental organizations and departments, educationalists and the public in general.

Satisfying Aspects
- making exciting new discoveries
- advancing particular fields
- working in a relatively stress-free environment

Demanding aspects
- focusing for long periods can cause eyestrain
- frustrations when trying to protect beneficial insects

An entomologist should:
- love nature;
- have a deep interest in insects;
- have an aptitude for mathematical and biological subjects;
- be willing to perform repetitive tasks
- be a careful and accurate worker
- have perseverance and patience
- enjoy laboratory work

School Subjects
National Senior Certificate meeting degree requirements for a degree course
National Senior Certificate meeting diploma requirements for a diploma course

Each institution will have its own minimum entry requirements.

Compulsory Subjects: Mathematics, Physical Sciences
Recommended Subjects: Life Sciences

Degree: The minimum requirement is a BSc degree but a BSc Honours degree is recommended, available at most universities. Major subjects include Entomology (or Zoology with Entomology as part of the curriculum) in combination with one of the following: Botany, Chemistry, Physiology, Microbiology, Mathematics, Plant Pathology or Genetics. Students can also follow a BSc (Agric) degree with Entomology as a major in combination with subjects such as Horticulture and Plant Production. Each university specializes in particular fields of zoology and it is recommended that prospective students first consult the yearbooks of different universities to ensure that a specific university offers courses in Entomology.
