Welcome to the Biological Control Site. This guide provides photographs and descriptions of biological control (or biocontrol) agents of insect, disease, and weed pests in North America. It is also a tutorial on the concept and practice of biological control and integrated pest management (IPM).


Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.It can be an important component of integrated pest management (IPM) programs.. There are three basic strategies for ...


Biological control or biocontrol is defined as "the use of a population of one organism to reduce the population of another organisms" (van Lenteren et al. 2017). It is based on an existing principle in nature: most organisms have one or more natural enemies by which populations of an organism are regulated, maintaining the balance between ...


Natural enemies have an extensive history of being used in applied biological control of plant pests throughout the world. Natural enemies, including predatory insects and mites, parasitic wasps and flies, and pathogenic bacteria, fungi, and viruses, have been used to manage pests on crop plants with some measure of success.


Lacewings (especially larvae; this one is an adult) are great natural enemies of pests. You want to keep them happy and healthy! Natural enemies of pests are going to help you out with pest control, so when you are applying pesticides, it’s in your best interest to choose products that will have the least impact on them.


Biocontrol provided by these living organisms (collectively called “natural enemies”) is especially important for reducing the numbers of pest insects and mites. Natural enemies also control certain rangeland and wildland weeds, such as Klamath weed (St. Johnswort).


Use of natural enemies for biological control of rangeland and wildland weeds (e.g., Klamath weed, St. Johnswort) is also effective. Plant pathogens, nematodes, and vertebrates also have many natural enemies, but this biological control is often harder to recognize, less well understood, and/or more difficult to manage. Conservation, augmentation, and classical biological control are tactics for h...


Why recognize natural enemies and spiders? These arthropods provide natural pest control by feeding on pest insects, including aphids, thrips, caterpillars and beetles that damage crops and other plants. The ability to distinguish natural enemies from pest insects will help you make informed pest control decisions.


Natural Enemies, the new Cannabis Division of Koppert Biological Systems, ships your predators directly to your farm, ensuring that you receive the freshest, highest-quality predatory insects on the market. Why Use Beneficial Insects? ∙ Safe & Effective ∙ Avoids chemical pesticide contamination


Biological control is an approach to reducing populations of harmful organisms with natural enemies. Organisms introduced from other parts of the world are called exotic or nonindigenous, as opposed to native or indigenous organisms. Pests may be introduced into the United States and become established without natural enemies to keep them in check.
