RESUMO

Sensilla are the basic structures of environmental cues perception, which play a role as mechanoreceptor, chemoreceptor, thermoreceptor and hygroreceptor associated with their morphology. Because bees have different sociability degree and foraging habits, they are an interesting model in studies about sensilla types and distribution associated with behavior. This work identified the types of sensilla in the antennae of bees species with different sociability degree and foraging habits. The antennae of Apis mellifera, Bombus atratus, Euglossa mandibularis, Friesella schrottkyi, Friseomelitta varia, Friseomelitta xanthopleura, Megalopta insignia, Melipona seminigra, Melipona asilvai, Melipona bicolor, Melipona crinita, Melipona flavolineata, Melitoma segmentaria, Plebeian emerina, P. lucii, P. Remota, P. Wittmanni, Pseudaugochlropsi graminae, Ptiloglossa sp., Oxaea flavescens, Scaura latitarsis, Scaura tenuis, Tetragona goettei, Tetragonisca angustula, Thygater analis and Xylocopa frontalis were analyzed with scanning electronic microscope. Sensilla trichodea are present in the scape, pedicel and in all antennomers of the studied species, following by sensilla placodea, that are present in all antennomers. Apis mellifera and Bombus atratus workers have higher diversity and sensillum distribution in comparison with males. In Meliponini, species of Melipona are representative of a homogeneous group for sensilla types and distribution. Workers of nocturnal solitary bees have higher sensilla diversity and distribution in comparison with diurnal and crepuscular solitary and eusocial bees. The types and distribution of sensilla in the antennae of bees are associated with the sociability degree and foraging habits.
