Scanning electron microscopic studies of antennal sensilla of adult worker Apis florea F (Hymenoptera: Apidae)

The micromorphology of the antennae of the honey bee Apis florea F was studied. The number and distribution of the various types of sensilla were examined. Sensilla observed were sensilla placodea, basiconica, trichodea, ampullacea, coeloconica and campaniformia. Sensilla trichodea were found most frequently and were present on all the antennal segments. Sensilla placodea and sensilla basiconica were present on 8 distal segments. Sensilla ampullacea and sensilla coeloconica were present on 5 distal segments while sensilla campaniformia were confined to 7 distal segments. The highest density of sensillae was found on the distal antennel segment. The distribution of different types of sensilla on the antenna resembled that described for other Apis species
