Abstract

In a laboratory choice-feeding test, groups of termites from five colonies of Coptotermes formosanus Shiraki were presented with wood blocks that had been previously damaged by nestmates; by conspecifics from another colony; by another termite species, Reticulitermes virginicus (Banks); and that had no damage. C. formosanus preferred wood previously damaged by conspecifics, regardless of colony origin, over wood damaged by R. virginicus or undamaged wood. Additionally, they preferred wood damaged by R. virginicus over undamaged wood. Covariate analyses and trail-following assay suggested that the results were almost entirely explained by thigmotaxic cues on the surface of damaged wood blocks rather than on pheromonal cues deposited on the wood.
