TL;DR: Despite the alterations observed in the ovipositor apparatus in the Orussidae, the musculature is almost complete and the mode of operation presumably not much different from that of other representatives of the Hymenoptera.

TL;DR: The sensilla ampullacea on the apical antennomere of the leaf-cutting ant Atta sexdens were investigated regarding both their responses to CO2 and their ultrastructure and it was confirmed that the sensillum are responsible for CO2 perception.

TL;DR: The ultrastructure and distribution of sensilla on the antennae of the cabbage stem flea beetle, Psylliodes chrysocephala, were investigated using scanning and transmission electron microscopy techniques and indicated that the hair plate sensilla and sensilla trichodea type one are probably mechanoreceptors, whilst the sensilla styloconica are probably thermo-hygro receptors.

TL;DR: The morphology and physiology of thermo-sensitive peg-in-pit sensilla of the leaf-cutting ant Atta vollen weideri were investigated and it was suggested that the S. coeloconica are involved in the recently described thermal orientation behavior of A. vollenweideri leaf- cutting ants.

TL;DR: In this article, a new terminology for antennal multiporous plates is discussed in relation to their different functions, and it is shown that these multiporous sensilla have tubular accessory glands that release their secretion through the socket sensillum only in scelionids.
