Entomologists are biological scientists who study insects. There are nearly a million known species of insects, and thousands of new species are discovered every year. Insects make up over three-quarters of all the species of animals. All insects play roles in ecosystems. Some roles are beneficial and some harmful to humans. Bees, for example, pollinate plants and produce honey. Many other insects help bacteria and fungi break down organic matter and form soil. Some insects damage growing crops and spoil harvests in storage. This causes farms to lose millions of dollars every year in the United States. They can also physically harm humans, pets, livestock, and wildlife. For instance, females of some species of Anopheles mosquitoes carry the causative agent of malaria and can transmit it to humans. Beetles can wipe out entire forests. An insect known as the screw-worm fly kills thousands of cattle each year.
Some entomologists study insects to learn more about their basic life processes. Others direct their research toward finding ways to control harmful insects and use desirable insects to advantage.
Entomologists are specialized zoologists or animal biologists. Their field is known as entomology. About one-third of all entomologists work for government agencies in fields such as agriculture and food inspection. Others are employed by colleges and universities. Companies that make insecticides, pest control companies, medical centers, and museums also employ entomologists.
