The Formosan subterranean termite (Coptotermes formosanus) is one of the most destructive termites in the United States and causes millions of dollars worth of damage each year. In this study we monitored Formosan subterranean termite alates weekly along a railroad connecting two towns with known established colonies using solar powered light traps to determine their distribution along the track. The terrain between the towns is rural and wooded, thus potentially good habitat for the termite. We also tracked alate captures in Poplarville, MS over a period of 4 years. The data collected is being used for colony location, determination of movement, and as one measure of treatment efficacy. Initial analysis shows a close association between alate captures and depots along the railroad.
