Feeding substrate selection is not affected by the soil and environment temperature during the foraging of Constrictotermes cyphergaster

Termites are known as wood consumers, although some species eat other substrates. Assessing resource selection is important to understanding their biology. The present study provides information on the foraging behavior of Constrictotermes cyphergaster (Blattaria, Termitidae) in a dry forest area of Caatinga in Brazil. We aimed to verify the frequency of resource exploitation by termites as a function of environmental and soil temperatures. We found no significant differences in resource exploitation as a function of temperature, which is interesting because this variable is often reported as modulating foraging activity in some other termite species. This species forages on open trails at high temperatures in the Brazilian semi-arid zone. Environmental changes may affect the dynamics of their behavior and, consequently, the ecosystem, since C. cyphergaster influences the carbon cycle and can modify the soil. Our study provides a basis for future research intending to understand the adaptations of this termite to live in the drylands.
