The biological study of insects that have a direct influence on humanity. Economic entomology is a subdiscipline of entomology (the biological science that deals with the investigation of insects) and focuses on the effects of insects on human economy, primarily with regard to agriculture. Although economic entomology includes beneficial as well as harmful species (Fig. 1), most attention is devoted to the latter and how they become pests and are controlled. The emphasis on managing harmful insects reflects the immediacy and seriousness of pest problems, particularly the destruction of agricultural products and the transmission of disease. These are highly visible problems, whereas the benefits gained from useful insects are, in many cases, not so clearly understood or so well documented economically.
