Olfactory sensilla on the antennae of the pine weevil, Hylobius abietis

Cell and Tissue Research, 1973
Olfactory sensilla on the antennal club of the pine weevil, Hylobius abietis, have been studied by scanning and transmission electron microscopy. Two main types, sensilla basiconica and sensilla trichodea, have been classified. The former are found in two variants, one containing one sensory cell and the other two.

Electrophysiological Recording from Drosophila Olfactory Sensilla [PDF]

Cold Spring Harbor Protocols, 2011
INTRODUCTIONThe chemical senses smell and taste detect and discriminate an enormous diversity of environmental stimuli and provide fascinating but challenging models to investigate how sensory cues are represented in the brain. Important stimulus coding events occur in peripheral sensory neurons, which express specific combinations of chemosensory ...

Molecular composition of the wall of insect olfactory sensilla—the chitin question [PDF]

Journal of Insect Physiology, 1999
Identification of chitin in sensory hairs of olfactory sensilla of silkmoths was performed using two independent methods. Firstly, ultrathin sections were labelled with gold-conjugated wheat germ agglutinin and showed positive labelling in the cuticule of sensilla as well as in the antennal cuticle. Secondly, isolated sensory hairs and body scales were

Electrophysiological characterisation of olfactory sensilla in the black bean aphid, Aphis fabae

Journal of Insect Physiology, 2004
Electrophysiological 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.

Structure and function of insect olfactory sensilla. [PDF]

Ciba Foundation symposium, 1996
Olfactory 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

Freeze-fracture characteristics of insect gustatory and olfactory sensilla

Cell and Tissue Research, 1982
Freeze-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 ...

Pore structures in insect olfactory sensilla: A review of data and concepts [PDF]

International Journal of Insect Morphology and Embryology, 1997
Abstract An historical overview is given of the most important discoveries and hypotheses regarding stimulus transport in insect olfaction. The great structural similarity between the pore tubules of olfactory single-walled wall-pore sensilla and the epicuticular filaments of non-olfactory cuticle may reflect not only a similar composition but also a

Species- and sex-specific distribution of antennal olfactory sensilla in two tortricid moths, Epiphyas postvittana and Planotortrix octo [PDF]

Micron, 2018
We investigated the morphology and distribution of antennal sensilla in males and females of two tortricid moths, Epiphyas postvittana and Planotortrix octo, by scanning electron microscopy.
