Slow The Spread (USFS and Indiana DNR)

Since its introduction into the United States in 1869, the European gypsy moth (Lymantria dispar) has defoliated thousands of acres of hardwood forests across the Northeastern United States. Originally introduced into Massachusetts, the gypsy moth has slowly spread north to Maine and south to North Carolina, infesting 19 States and the District of Columbia. Over the decades, the infestation continues to move south and west.

In 1992, the U.S. Department of Agriculture's (USDA) Forest Service (FS) and Animal and Plant Health Inspection Service (APHIS), along with the Department of Interior's National Park Service and eight State and university partners embarked on a pilot project called “Slow the Spread.” The project’s goal was to slow the rate of natural spread of the gypsy moth by using integrated pest management strategies.

The project demonstrated that it is feasible to significantly reduce the spread of gypsy moth and that this can be accomplished in a cost–effective and environmentally viable manner using current technology.

In 1999, following successful completion of the pilot project, the National Gypsy Moth Slow the Spread program was implemented along the entire 1,200 mile gypsy moth frontier from North Carolina through the upper peninsula of Michigan.
