- Abstract
Maximizing food intake while minimizing risk is an important trade-off in the foraging behavior of most animals. In general, foragers are vulnerable and the ability to trade off benefits (food quantity) against costs (risk of being killed) may provide a considerable ecological advantage. Despite the increasing number of studies, the effects of food quantity and mortality risk signals on resource selection in eusocial insect is not well understood. Here, we investigated the combination of distinct levels of food quantity and the intensity of alarm signal on resource selection of a Neotropical termite, Nasutitermes corniger (Motschulsky) (Termitidae: Nasutitermitinae). Manipulative bioassays with binary and multiple choices were conducted over time to check the recruitment of termite groups among resources containing different levels of food quantity and alarm signals. Overall, our results showed that regardless of food quantity, termites avoid a food source if there is even a small amount of alarm signal. This work contributes to a better understanding of habitat use by termite species. Furthermore, it shows for the first time the combined effects of food quantity and alarm signals on the resource selection of an important ecological and economic termite species.
