Among several termite species in the genus Reticulitermes present in the United States, four of them (R. flavipes, R. tibialis, R. virginicus, and R. hesperus) along with the invasive species Coptotermes formosanus account for 90 percent of termite control business. Rapid identification is a critical part of management efforts, and a team of researchers has developed a new, faster ID method that uses a genetic tool called inter-simple sequence repeats. Shown here are the ranges (shaded) and sampling sites (dots) of Reticulitermes termite species included in the study.
