- Abstract
The sensilla are sensitive structures located in different insect parts including the antennae. They are responsible for the hygro-, chemo-, thermo- and mechanoreception. In the present work the antennal topography of two different populations of Melipona scutellaris Latreille (Hymenopera: Apidae) from different altitudes (200 and above 900m) were studied considering the last three distal antennal flagelomers (F). Images of the antennal surface were obtained with the aid of the scanning electron microscope (SEM). The SEM analysis showed that the sensilla placodea, basiconic, coeloconic, ampullacea, campaniform and trichodea are present in the dorsal surface of the M. scutellaris antennae. The number of sensilla trichodea of the straight subtype is greater in the last three flagelomers in individuals of 200m altitude, while individuals located above 900m altitude has a greater number of sensilla trichodea of the subtype curved in the F9 and they have greater length in individuals of 900m altitude only in the F10. These differences were discussed according to the geographic location of the different groups studied here. This work represents the first assessment to antennal structure of M. scutellaris and contributes to a better understanding of the biology of this species.
