Fine structure of olfactory sensilla in myriapods and arachnids

Microscopy Research and Technique, 1992
AbstractStructural features of various types of olfactory sensilla are reviewed. (1). Sensilla basiconica which differ in form and size are found on the antennae of centipedes and millipedes. Their walls show longitudinal slits or grooves that either open into the sensillum lumen or do not penetrate the cuticle. In other such sensilla the outer surface

Functional specialisation and polyphenism in aphid olfactory sensilla

Journal of Insect Physiology, 2002
Electroantennogram (EAG) responses to the aphid sex pheromone components, (1R,4aS,7S,7aR)-nepetalactol and (4aS,7S,7aR)-nepetalactone, and a plant volatile, (E)-2-hexenal, were investigated at three different positions (5/6th, 4/5th and 3/4th inter-segmental regions) along the antennae of four different morphs in two host-alternating aphid species ...

Mechanosensitive and Olfactory Sensilla of Insects

1984
Insects are the most successful land dwellers among the invertebrates. They owe this achievement largely to their cuticle, which provides mechanical support and protects against water loss at the same time. This exoskeleton forms a barrier between the environment and the interior milieu, so that sense organs need unique adaptations to remain accessible

Esterase activity in the olfactory sensilla of the silkmoth Antheraea polyphemus

NeuroReport, 1995
We studied in individual males of Antheraea polyphemus the activity of the sensillar esterase, a pheromone-degrading enzyme present in the sensillum lymph surrounding the olfactory receptor cells. In parallel, receptor potentials from single pheromone-sensitive sensilla trichodea were recorded.

Honeybee olfactory sensilla behave as integrated processing units

Behavioral and Neural Biology, 1994
Honeybee placode sensilla contain 18-35 olfactory receptor neurons. In insects, such neurons are thought to not interact with one another before reaching the central nervous system. Extracellular, multiunit recordings were made from the placodes and separated into spike shape classes, termed subplacode units.

Cell degeneration during early development of hymenopteran olfactory sensilla

Tissue and Cell, 1983
The imaginal pore plates of Hymenoptera apocrita so far examined embody five or six envelope cells respectively. In early developmental stages, however, supernumerary envelope cells have been found. The results are discussed in the context of cell death as a developmental phenomenon.

Drosophila olfactory sensilla

2006
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, 1987
X-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.

Olfactory sensilla in crustaceans: Morphology, sexual dimorphism, and distribution patterns

International Journal of Insect Morphology and Embryology, 1997
Abstract 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.
