Modern classical biological control programs mandate extensive testing of the natural enemy host ranges before introduction so that the selected natural enemies attack only the intended target pest and do not cause harm to other non-target organisms. Because of the long, rigorous, and costly process of finding, testing, quarantining, and rearing these natural enemies, classical biological control programs are typically conducted by scientists at governmental agencies or universities with public funding. Some notable examples of classical biological control include the use of decapitating flies (several Pseudacteon species) against red imported fire ants, and a group of flea beetles, thrips, and stem borers used against alligator weed. 1 Often, the natural enemies are found in the home range of the invasive pest. Classical Biological ControlД¬lassical biological control refers to the practice of introducing one or a group of natural enemy species of foreign origin to control a pest that many times is also foreign in origin (called exotic, introduced, or invasive). There are three general approaches to biological control. Natural enemies are utilized differently depending on the target pest, host, environmental condition, and pest life cycle. The ultimate goal of biological control is to suppress pest population and damage without pesticide or with reduced pesticide use. In nature, organism populations suffer frequent attacks and high mortality rates from predators, parasites, parasitoids, and diseases, collectively called вЂњnatural enemies.вЂќ Biological control tactics use natural enemies or agents (some practitioners call them вЂњbeneficialsвЂќ) to manage pests. For the purposes of this publication, pests are defined as any undesirable insect, mite, plant (weed), or organism that causes disease (pathogen) or damage on ornamental plants, turfgrasses, fruits, and vegetables.

This publication provides an introduction to biological control and explains how to integrate biological control into an integrated pest management (IPM) program. Biological control can also be used to manage pest populations that have developed pesticide resistance. The benefits of biological control include reduced reliance on pesticides, decreased potential for development of pesticide resistance, flexibility in usage of personal protective equipment, shorter (or no) restricted entry intervals, and reputational benefit of being a sustainable and responsible grower or professional. Growers and green industry professionals are searching for alternative pest management tactics to satisfy consumer demands and the desire for sustainability and operational flexibility. Not only are the negative health and environmental risks of pesticides of concern but also the impacts of neonicotinoids and other broad-spectrum pesticides on pollinators and other beneficial organisms. Consumers are becoming more concerned about pesticide usage on ornamental plants and turfgrass in and around their homes and on the fruits and vegetables they eat.
