dc.description.abstractIn stingless bees, unlike honey bees, the relationship between chemosensory abilities and colony labor division has been poorly studied. Here we examined odor reception and gustatory responsiveness of the stingless bee Tetragonisca angustula focusing on workers, whose are involved in different tasks. Using the proboscis extension response, we studied sucrose response thresholds (SRTs) of foragers and guards. Peripheral responses to odors at the antennae were recorded by electroantennography (EAG). Additionally, we quantified and described the number and type of sensilla present on the antennae using scanning electron microscopy. Foragers’ SRTs changed according to the resource collected: nonpollen foragers showed higher SRTs than pollen foragers and guards, that showed similar sucrose responsiveness. EAG signal strength of both foragers and guards increased with increasing odor concentration. Interestingly, guard bees showed the highest response to citral, an odor that triggers defensive behavior in T. angustula. Type and number of sensilla present in the antennae of guards and foragers were similar. Our results suggest that differences found in chemosensory responses among worker subcastes are task dependent.
