Abstract

Social insects exhibit sophisticated behavioral repertoires to maintain communication and regulate colony activities. To elucidate the behavioral mechanisms of social insects is essential a thorough understanding of morphophysiological characteristics, such as the functionality of exocrine gland secretions. In this study, it was analyzed whether the mandibular gland secretions influence the aggregation behavior of workers of the ant Paraponera clavata. Associated behavioral acts were also studied. Bioassays indicated that mandibular gland extract triggers aggregation behaviors in P. clavata workers. The observed behavioral acts include mandible opening, raising of the antennae, antennal contact with treated filter paper, selfgrooming, cleaning of the abdominal tip, and allogrooming. These observations demonstrate the potential multifunctionality of compounds secreted by mandibular glands within the behavioral repertoire of P. clavata.
