The privilege of studying the spread of an exotic pest species from its first recorded appearance is a rare event. Usually, the population of interest has expanded to cover many political entities before the problem is even detected. Point of introduction has to be deduced by indirect means. Year by year activity of the pest becomes anecdotal rather than measured. In this paper we discuss the spread of the Formosan subterranean termite, Coptotermes formosanus in Rockport, Texas from its first discovery in 1997 to the present.
Colonizing by the termite has followed classic lines radiating from the point of introduction along corridors in a manner predictable by the weather patterns, nature of the environment and availability of hosts. This species readily colonizes woody plants as well as structures made of wood.
Data from other known single introduction points continue to follow the same model.
