Biological Control

Indiscretus and gypsy moth Biological control (biocontrol) involves the reduction of pest population densities through the use of natural enemies (parasitoids, predators, pathogens). Once these natural enemies are established, populations are self-sustaining and can be implemented as part of an Integrated Pest Management (IPM) Program.

Classical Biological control is the intentional introduction of non-native natural enemies for permanent establishment and long-term control of invasive species in the newly infested area. It is a proven target specific strategy that has been used extensively to control non-native species.


The goal of the Washington Office Forest Health Protection (FHP) Biological Control Program is to promote, facilitate and provide leadership in the development and use of biological control agents in response to increased threats to forest health and sustainability from non-native and invasive species.

Program Coordination

The responsibility for national coordination of biological control activities resides within the Forest Health Technology Enterprise Team (FHTET) in Morgantown, West Virginia. Regional coordination and program implementation occurs in the regional offices. Scientific and technical support is provided by FHTET in support of regional activities, publications, training and workshops.
