The present paper discusses the ultrastructure of antennal sensilla (scanning electron microscopy-SEM) and the electroantennographic recordings (EAG) from the olfactory sensilla responding to the proposed chemicals, also considering the literature on chemical ecology and olfaction of aphidophagous ladybugs. (unipg.it)
In particular, antennal sensilla are similar to those described in predatory species but in Epilachnini they are much more numerous on the apical flagellum, probably because involved in host plant location and selection. (unipg.it)
The third antennal segment (flagellum) bears four types of multiporous sensilla: trichoid, short basiconica, clavate and grooved. (unica.it)
Electrophysiological investigations proved that antennal sensilla are responsive to bacterial filtrate odor, methyl thiolacetate, olive leaves and olives, as well as to a-pinene, while acetic acid elicited an inhibitory response. (unica.it)
Thus, both sensilla located at the antennal base of scutigeromorph centipedes fulfill a dual function. (biomedcentral.com)

Results 】 The labial palp of P. xylostella adults consists of three segments, on which there are five types of sensilla, including B ö hm bristles, sensilla campaniformia, sensilla squamiformia, sensilla basiconica, and microtrichia, and a labial - palp pit organ (LPO). (insect.org.cn)
Sensilla squamiformia are willow leaf - like, sensilla basiconica are thick and straight, and both are scattered on the 2nd and 3rd segments, with significant differences in size between sexes. (insect.org.cn)
Recordings1
We made long-term extracellular recordings from the bases of peg sensilla and used a combination of conditional cross-interval and conditional interspike-interval analyses to assess the temporal dynamics of the A and B spike trains. (nih.gov)
Densely covered1
The tip of the antenna, regardless of caste identity, is more densely covered with sensilla compared with the base of this organ. (lsuagcenter.com)

Sensory structures2
arthropod sensory structures consisting of special sensilla called the scolopidia, which are mechano-transducers and respond mainly to stretch or flexion. (eol.org)
The termite antenna is shaped like a chain of beads, and each antenna is covered by hundreds of tiny sensory structures called sensilla. (lsuagcenter.com)

Bristles1
B ö hm bristles are spine - like, sensilla campaniformia have circular dome surrounded by a cuticular rim, and both of the two sensilla were found only on the 1st segment of labial palp, without significant differences in size between sexes. (insect.org.cn)
Sexual dimorphism1
Sensilla squamiformia in females are significantly larger than those in males, and this sexual dimorphism suggests that this type of sensilla of female are likely associated with sensing of host plant odours. (insect.org.cn)
Medial5
And medial (F2,29 = 31.7, P 0.0001) sensilla. (igf-1r.com)
Accordingly, the Q10 values for the AA response in the medial and lateral styloconic sensilla were, in respective order, 1.9 and 2.2 in the low temperature range (i.e., 14 22 ) and 2.6 and two.2 in the high temperature variety (i.e., 22 30 ).Identification of M. sexta Trp genes and analysis of TrpA1 expression in chemosensory tissues (Experiment 2)(Matsuura et al. (igf-1r.com)
If MsexTrpA1 mediated the temperature-dependent response to AA in Figure two, then we predicted that it should be expressed in GRNs inside the lateral and medial styloconic sensilla. (igf-1r.com)
As shown in Figure 5, we detected expression of TrpA1 in GRNs within the lateral and medial styloconic sensilla. (igf-1r.com)
In contrast, there was a substantial primary effect of mecamylamine on the response of each the lateral and medial styloconic sensillum to AA (in both instances, F2,29 24.0, P 0.0001). (igf-1r.com)

Exoskeleton2
The slit sensilla, also known as the slit sense organ, is a small mechanoreceptory organ or group of organs in the exoskeleton of arachnids which detects physical deformation or strain due to forces experienced by the animal. (wikipedia.org)
despite this appearance, however, investigation has shown that slit sensilla do not actually penetrate the chitin of the exoskeleton, but merely represent a thinning of the material. (wikipedia.org)
Organ3
The term "lyriform organ" comes from the shape of such grouped slit sensilla, which resembles a lyre. (wikipedia.org)
House centipedes (Scutigeromorpha) possess a peculiar opening at the base of their antenna, termed 'scape organ', that houses up to 15 cone-shaped sensilla in a cavity. (biomedcentral.com)
The cone-shaped sensilla in the scape organ as well as nearby peg-shaped sensilla are composed of three biciliated receptor cells and three sheath cells. (biomedcentral.com)

Segments4
Receptor cell type 1 (two cells in cone-shaped sensilla, one cell in peg-shaped sensilla) possesses two long dendritic outer segments that project to the terminal pore. (biomedcentral.com)
Receptor cell type 2 (one cell in both sensilla) possesses two shorter dendritic outer segments connected to the first (proximal) sheath cell that establishes a scolopale-like structure, documented for the first time in detail in a myriapod sensillum. (biomedcentral.com)
The nearly identical configuration of receptor cells 1 with their long dendritic outer segments in both sensilla is similar to hexapod hygroreceptors. (biomedcentral.com)
The interconnection of receptor cell 2 with short outer dendritic segments to a scolopale-like structure potentially suits both sensilla for vibration or strain detection. (biomedcentral.com)
