The coelocapitular sensillum, an antennal hygro- and thermoreceptive sensillum of the honey bee, Apis mellifera L.

Cell and Tissue Research, 1983
The sensillum coelocapitulum, a hygro- and thermoreceptive sensillum of the honey bee, Apis mellifera, was investigated by electron microscopy. The cuticular apparatus of the sensillum is a mushroom-shaped protrusion, devoid of pores, set in a narrow cylindrical pit positioned centrally within a cuticular, shallow depression. There may be three or four

Antennal Sensillum Morphology and Electrophysiological Responses of Olfactory Receptor Neurons in Trichoid Sensilla of the Diamondback Moth (Lepidoptera: Plutellidae)

Florida Entomologist, 2016
Plant chemical signals are important olfactory cues for the survival and reproduction of phytophagous insects. The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae) is a Brassica spp.

Sensillum development in the absence of cell division: The sensillum phenotype of the Drosophila mutant string

Developmental Biology, 1990
We have investigated sensillum development in Drosophila embryos homozygous for mutations in the locus string (stg). In these embryos, cell division is blocked following blastoderm formation. This permits a study of the differentiative fate of undivided precursor cells, in particular those giving rise to the larval sensory organs (sensilla).

Evidence for a role of SNMP2 and antennal support cells in sensillum lymph clearance processes of moth pheromone-responsive sensilla [PDF]

Insect Biochemistry and Molecular Biology
In insect antenna, following the activation of olfactory sensory neurons, odorant molecules are inactivated by enzymes in the sensillum lymph. How the inactivation products are cleared from the sensillum lymph is presently unknown.

Electrical circuitry of an insect olfactory sensillum

Neurocomputing, 2001
Abstract A biophysical model of an insect olfactory sensillum in steady-state conditions is presented. The model has two distinguishing features. Firstly, it describes analytically the extracellularly recorded potential, thus closing formally the gap between theoretical models and experimental results.

Combined Gas Chromatography and Single Sensillum Recording for Mosquitoes

Cold Spring Harbor Protocols, 2022
Combined gas chromatography and single sensillum recording (GC-SSR) joins together the established volatile compound separation and relative quantification techniques of GC with the ability to functionally screen olfactory sensory neurons (OSNs) for volatile selectivity and sensitivity using SSR.

Pattern, time of birth, and morphogenesis of sensillum progenitors in Drosophila

Microscopy Research and Technique, 1997
In this paper we describe the spatiotemporal pattern of sensillum progenitors (SOPs), as well as the way in which these cells segregate from the ectoderm and proliferate. The birthdate of SOPs was determined by applying short heat pulses to embryos carrying the Nintra construct [Struhl et al. (1993), Cell, 74:331-345] which allows the overexpression of

Functional morphology of a double-walled multiporous olfactory sensillum: the sensillum coeloconicum of Bombyx mori (Insecta, Lepidoptera)

Tissue and Cell, 1998
The fine structure of coeloconic sensilla of Bombyx mori was studied in cryofixed specimens. These sensilla belong to the category of double-walled wall-pore sensilla. The pegs are approximately 10 microm long, located in pits on the dorsal side of the antennal branches, and longitudinally grooved in their distal half (grooved surface approximately 30 ...

To be or not to be… a vampire: A matter of sensillum numbers in Calyptra thalictri?

Arthropod Structure & Development, 2010
The mechanisms by which blood feeding in insects has evolved are unclear, primarily because there has been no access to species in which there is a mixture of same-sex blood feeding and non-blood feeding individuals. The discovery of a subset of male Calyptra thalictri (Lepidoptera: Noctuidae: Calpini) that blood feed under constrained experimental ...

Electroantennogram and Single Sensillum Recording in Insect Antennae

2013
Electrophysiology is an invaluable technique to quickly and quantitatively assess the response of the olfactory system to odor stimuli. For measuring the response of the insect antenna, two basic techniques exist, electroantennography and single sensillum recording.
