The response of Coptotermes formosanus to substrates and food sources treated with Vetiver oil (from Vetiveria zizanioides) and one of its components, nootkatone, was investigated. The results showed that these compounds were able to disrupt termite behaviour and physiology as a consequence of direct physical contact, ingestion, or exposure to the vapours. In the presence of these compounds, termites showed a 'lingering behaviour', remaining on the surface all clumped together, unable to organize themselves to reach potential food sources through tunnelling activity or building shelter tubes. Ingestion of wood treated with Vetiver oil or nootkatone resulted in the progressive death of the protozoa population living inside the termite gut.
