Diversity and distribution of ground-dwelling and arboreal termites in a Panamanian rainforest

 

IBISCA social-insect team: Alain Dejean & Jerôme Orivel (Université Paul Sabatier, Toulouse, Evolution & Diversité Biologique), Bruno Corbara (Université Blaise-pascal, LAPSCO, Clermont-Ferrand), Yves Roisin (Université Libre de Bruxelles), Maurice Leponce

with the help of the Mary V. Walcott Endowment Trust.

 

The termite collection was based on visual search which is the most efficient method for this taxon. Additional specimens were collected by other sampling protocols run simultaneously, such as Berlese, Winkler, pitfalls, light traps, flight interception traps ... ran simultaneoulsy by other sampling programs.

We collected in various sites of San Lorenzo forest to compare the diversity of arboreal and ground-dwelling termites

Dead branches in the canopy were searched for termites.

Direct access to arboreal termite colonies was made possible thanks to the presence on site of the Solvin-Bretzel canopy raft, of the canopy bubble, of the Ikos and  of Fort Sherman canopy crane. Professional climbers  were also of great help to collect material. 

Nasutitermes were among the most frequent arboreal species.

 

All dead wood was systematically searched for termites.

Flight interception traps and light traps were useful to collect alates.

Soldierless Apicotermitinae galleries were found in soil scrapes

A variant of the standardized protocol for collecting termites (Jones & Eggleton 2000, Roisin & Leponce 2004) was used at ground level. It consists in 400 m long transects, divided in 40 successive quadrats of 5m².
