The National Slow the Spread (STS) Program  represents one of the longest running and most geographically expansive integrated pest management programs in the world. 

The program’s goal is to slow the rate of spread of spongy moth, Lymantria dispar L. (Lepidoptera: Erebidae, formerly known as the “gypsy moth”), by greater than 60 percent from its historical rate of spread (19.6 km/yr, an average of historical spread rates) in the United States (Liebhold et al. 1992). The  Slow the Spread Foundation, a non-profit foundation, together with 12 states, two federal agencies, and two universities, have contributed to the success of the program since its inception in 2000.
