Biological practices include using one organism to control another, as in attracting or releasing beneficial insects that are natural enemies of pest species into the landscape and protecting the beneficials that exist in the landscape. For more information, see: Detailed information on biological control.

Areas closely related to biological control include use of synthetic products to affect biological systems.

• Some synthetic insecticides are based on insect hormones and affect populations by preventing insects from developing into mature adults.

• Insect communication chemicals have been extracted, identified and synthesized into products used to: 1) monitor presence and abundance of insect pests; 2) disrupt mating by saturating the environment to prevent individuals from finding one another; or 3) attract target pests to toxic substrates.
