Forest Service Accepting Public Comments on Spongy Moth Suppression

The US Department of Agriculture, Forest Service is seeking public input on a proposal to expand treatment methods for suppressing spongy moth (Lymantria dispar dispar) outbreaks on the Allegheny National Forest. Previously known as the gypsy moth, this invasive species poses a significant threat to forest health.

Proposal Details

Currently, the Forest Service uses Bacillus thuringiensis kurstaki (B.t.k.), a naturally occurring bacterium, for aerial applications to control spongy moth populations. The new proposal suggests expanding the range of approved treatment methods to include:

• Tebufenozide: An insect growth regulator that disrupts the molting process of caterpillars.
• Gypchek: A viral insecticide specific to spongy moths.
• Future Treatment Protocols: A protocol for approving other effective methods in the future.

Collaborative Efforts

The Allegheny National Forest is working in partnership with the Pennsylvania Department of Conservation and Natural Resources and the USDA Forest Service State and Private Forestry. Together, they conduct egg mass surveys to monitor population trends and determine the best management responses to control the spongy moth and mitigate defoliation.

Public Involvement

The Forest Service values public input and invites comments on the proposed activities. A draft supplemental environmental assessment detailing the proposal is available for review at Forest Service Project Page. Printed copies can be requested as well.

Understanding the Name Change

The Entomological Society of America has discontinued the use of the name “gypsy moth” due to its offensive connotations. More information about this change can be found at Entomological Society of America.

Public participation is crucial in managing the health of our forests. Your comments and feedback on the proposed spongy moth suppression methods will help the Forest Service make informed decisions to protect the Allegheny National Forest. Visit the project page, review the assessment, and submit your comments by April 25, 2022.
