Termite nests provide a controlled environment and physical defence for the colonies of insects they house. Another important factor involved in colony defence may be volatile chemicals present in the nest: we have found the hydrocarbon naphthalene in extracts of the nest material produced by Formosan subterranean termites. This is the first time naphthalene has been found naturally associated with any insect species. 

Nootkatone Is a Repellent for Formosan Subterranean Termite (Coptotermes formosanus)

Nootkatone, a sesquiterpene ketone, isolated from vetiver oil is a strong repellent and toxicant to Formosan subterranean termites.

Naphthalene, an insect repellent, is produced by Muscodor vitigenus, a novel endophytic fungus.

Muscodor vitigenus is a recently described endophytic fungus of Paullinia paullinioides, a liana growing in the understorey of the rainforests of the Peruvian Amazon. This fungus produces naphthalene

Approaches to biological control of termites

Fungi and nematodes have received the greatest attention to date, and a few commercial formulations are either available or on the near horizon, but their field efficacy is not well documented.

Antimicrobial Compounds in the Volatilome of Social Spider Communities

The results indicate the potential relevance of the volatilomes for the ecological success of S. dumicola and suggest that social arthropods are protected by chemical compounds produced by the arthropod themselves, microbial symbionts, or plants they associate with.

Exploring the Caste-Specific Multi-Layer Defense Mechanism of Formosan Subterranean Termites, Coptotermes formosanus Shiraki

The findings indicated that the volatile chemistry of nest-mates and genes encoding antioxidant defense greatly contribute to the survival and foraging of Formosan subterranean termites in a microbe-rich habitat.

Home economics in an oak gall: behavioural and chemical immune strategies against a fungal pathogen in Temnothorax ant nests

A positive correlation between fungistatic activity and colony size is revealed, indicating that workers of smaller colonies do not invest a higher per capita effort in producing such substances compared to larger colonies.

Growth response of Metarhizium anisopliae to two Formosan subterranean termite nest volatiles, naphthalene and fenchone

The entomopathogenic fungus Metarhizium anisopliae (Metschnikoff) Sorokin was investigated as a control agent against the Formosan subterranean termite, Coptotermes formosanus Shiraki, and its effectiveness against termite species has been demonstrated; use of this fungus in an integrated pest management scheme may be effective.

Fungistatic Activity of Freshly Killed Termite, Nasutitermes acajutlae, Soldiers in the Caribbean

Fungi that grew from termites were mostly non-pathogenic, suggesting the anti-fungal properties of soldiers may inhibit both pathogens and competitors.

Inhibition of Fungal Spore Germination by Nasutitermes: Evidence for a Possible Antiseptic Role of Soldier Defensive Secretions

The results suggest that although Nasutitermes terpenoid secretions may have antifungal properties, the caste composition of groups and the social interactions of termites also play a role in determining susceptibility to fungal infection.
