Differences in tunneling behavior of Coptotermes vastator and Coptotermes formosanus (Isoptera: Rhinotermitidae).

In a laboratory assay, Coptotermes vastator tunnels were observed to be thinner and to be more highly branched with an extensive network of cross-tunnels, than those of Coptotermes formosanus. This represents the first report on C. vastator tunnel systems.
