Studies on the antennal sensilla of selected blackflies (Diptera: Simuliidae)

Canadian Journal of Zoology, 1973
The types, numbers, and distribution of the antennal sensilla of male and female Simulium rugglesi and S. baffinense, and female S. venustum and S. euryadminiculum have been determined. Seven sensillar types, including olfactory receptors, contact chemoreceptors, and mechanoreceptors, were distinguished on all specimens examined.

External morphology and abundance of antennal sensilla in australian gryllacrididae

Journal of Morphology, 1994
AbstractThe long (49–93 mm) antennae of two species of Australian gryllacridids have high total numbers of sensilla consisting of five sensillar types. Ametrus sp. 7 has 22,300 (♀) and 26,250 (♂) sensilla; although the antennae of males are 33% longer than those of females, their sensillar density was 11% less. Bothriogryllacris pinguipes has 26,700 (♂)

Antennal sensilla ofNeomysis integer (leach)

Protoplasma, 1978
The most frequent type of the hair sensilla on the antennae ofNeomysis integer is investigated by electron microscopic methods. The cellular properties of the sensilla are compared with those of other arthropods in order to detect possible homologies.

Antennal and Mouthpart Sensilla of Tetrigidae (Orthoptera)

Annals of the Entomological Society of America, 1991
Sensilla on the antennae and mouthparts of eight species in six genera of Tetrigidae were observed using scanning electron microscopy. Tetrigines had multiporous placoid sensilla, mound-shaped sensilla with a distal peg on the scape and pedicel, and cylindrical basiconic sensilla with an apical papilla.

Structure of the antennal chordotonal sensilla of the American cockroach

Journal of Ultrastructure Research, 1985
Abstract The structure of the chordotonal sensillum in the antennal pedicel of the American cockroach has been examined. The sensillum contains two receptor cells, the sensory dendrites of which give rise to a single sensory cilium. The dendrites are attached by extensive desmosomes to a surrounding scolopale cell.

A comparative study of the antennal sensilla in corbiculate bees

Journal of Apicultural Research, 2014
SummarySensilla are the basic structures that allow the perception of environmental cues that play a role as mechanoreceptors, chemoreceptors, thermoreceptors and hygroreceptors associated with their morphology. Because bees have different degrees of sociability, they are a good model for the study of sensilla types and distribution linked with ...

Fine structure of antennal sensilla coeloconica of culicine mosquitoes

Tissue and Cell, 1973
Abstract The sensilla coeloconica (pegs in pits) previously mis-identified as campaniform organs, at the tip of the antennae of female Aedes aegypti L. and Culexpipiens (L.) are described. Each sensillum is innervated by three bipolar neurons: the dendrites of two are unbranched whereas the distal portion of the third is folded into tightly packed ...

The Antennal Sensilla of Species of thePalpalisGroup (Diptera: Glossinidae)

Journal of Medical Entomology, 2015
Infection of tsetse fly with trypanosome parasites could be influenced by its ability to locate vertebrate host(s) in the wild. Generally, the antennae of insects are known to bear chemo-sensory organs (sensilla), which are used for host search among other functions.

Density of Antennal Sensilla Influences Efficacy of Communication in a Social Insect

The American Naturalist, 2013
Effective communication requires reliable signals and competent receptors. Theoretical and empirical accounts of animal signaling focus overwhelmingly on the capacity of the signaler to convey the message. Nevertheless, the intended receiver's ability to detect a signal depends on the condition of its receptor organs, as documented for humans.
