Description: Invasions by alien species can cause substantial damage to our forest resources. The gypsy moth (Lymantria dispar) represents one example of this problem, and we present here a new strategy for its management that concentrates on containment rather than suppression of outbreaks. The "Slow the Spread" project is a combined federal and state government effort to slow gypsy moth spread by detecting isolated colonies in grids of pheromone-baited traps placed along the expanding population front from Wisconsin to North Carolina. Detected colonies are treated using Bacillus thuringiensis or mating disruption. Analyses to date indicate that this project has reduced spread by more than 50 percent.

Keywords: entomology and pathology, integrated pest management, invasive species
