We studied two aspects of Drosophila olfactory sensilla. In the first part we investigated the modulatory role of biogenic amines in sensilla. We detected expression of receptors for the biogenic amines serotonin, dopamine, octopamine and tyramine in the antenna, and showed that loss of the tyramine receptor in the mutants TyrRhono and TyrRhono ...

The Electrolyte Distribution in Insect Olfactory Sensilla as Revealed by X‐ray Microanalysis
Annals of the New York Academy of Sciences, 1987X-ray microanalysis allows the quantitative analysis of elemental concentrations in situ with the high lateral resolution of the electron microscope.'Thus, it is now possible to measure the electrolyte distribution directly in the various cellular and extracellular compartments of insect sensilla.

Electrophysiological characterisation of olfactory sensilla in the black bean aphid, Aphis fabae
Journal of Insect Physiology, 2004Electrophysiological responses of three different olfactory sensilla (proximal primary rhinaria (PPR), distal primary rhinaria (DPR) and secondary rhinaria (SR)) to the sex pheromone components, nepetalactol, nepetalactone, and a plant volatile, (E)-2-hexenal, were investigated in four different morphs of the black bean aphid, Aphis fabae Scopoli.

Freeze-fracture characteristics of insect gustatory and olfactory sensilla
Cell and Tissue Research, 1982Freeze-fracture data on antennal olfactory and labellar gustatory sensilla of the blowfly Calliphora vicina were compared with those of vertebrate olfactory organs. Insect antennal and vertebrate olfactory axons have similar diameters and show vesicular expansions; insect labellar axons are on average twice as thick and show no vesicular expansions ...

Development and Growth Patterns of Olfactory Sensilla in Malacostracan Crustaceans
2002Olfactory sensilla (aesthetascs) in malacostracan crustaceans have similar growth patterns. Detailed evidence in larval Carcinus maenas indicates that the medial aesthetascs are the first to be added on a new segment; more lateral aesthetascs occur later. When a new segment has received its maximum number of aesthetascs, new aesthetascs are added basal

Olfactory sensilla in crustaceans: Morphology, sexual dimorphism, and distribution patterns
International Journal of Insect Morphology and Embryology, 1997Abstract The morphological variation of crustacean olfactory sensilla is considerable, and appears to comprise both aesthetascs and male-specific sensilla. Male-specific sensilla have hitherto been described in some non-decapod groups, whereas the sexual dimorphism of the olfactory system of decapods is usually less prominent morphologically.

Ultrastructure of the aesthetasc (olfactory) sensilla of the spiny lobster, Panulirus argus
Cell and Tissue Research, 1988The aesthetascs of the spiny lobster, Panulirus argus, are hair sensilla located on the lateral filaments of the antennules. Each hair is about 0.8 mm long and innervated by about 320 bipolar sensory neurons, the dendrites of which project as a bundle into the hair shaft. Each of the dendrites develops two cilia.

Abstract The antennal sensilla of male and female Pseudoperichaeta nigrolineata Walker (Diptera: Tachinidae) were studied by scanning electron microscopy. Five types of sensilla were identified on the funicle. The trichoid sensilla are most conspicuous, with a characteristic distal curvature and wall pores.

Structure and function of insect olfactory sensilla.
Ciba Foundation symposium, 1996Olfactory sensilla show a large diversification of sensillum types even in the same species. Thus, double-walled and single-walled sensilla with highly different wall pores are usually found on the same antenna, and these may appear in the form of long slender hairs, pore plates or pit pegs. The selective constraints leading to this diversification are
