The USDA Forest Service is accepting public comments on a proposal to suppress gypsy moth populations in Allegheny National Forest.
The Forest Service has partnered with the state Department of Conservation and Natural Resources, and USDA Forest Service State and Private Forestry to conduct gypsy moth egg mass surveys to assess population trends. Preliminary results show notable egg mass numbers, especially in oak forests north of Route 59, according to the Forest Service.
Proposed action includes aerial application of a naturally occurring native bacterium – Bacillus thuringiensis var. kurstakii (Btk) – to the crowns of overstory trees. Treatments could begin as early as April and would continue in future years as needed.
