Economic entomology

Economic entomology is a field of entomology, which involves the study of insects that benefit or harm humans, domestic animals, and crops. Insects that pose disadvantages are considered pests. Some species can cause indirect damage by spreading diseases, and these are termed as disease vectors. Those that are beneficial include those that are reared for food such as honey, substances such as lac or pigments, and for their role in pollinating crops and controlling pests.
