Description of the antennal sensilla of Habrobracon Hebetor
BioControl, 2007The morphology of the antennal sensilla of both male and female Habrobracon hebetor (Say) (Hymenoptera: Braconidae) is described using Scanning Electron Microscopy complemented with Transmission Electron Microscopy. Five types of innervated sensilla as well as uninnervated microtrichia were found. These types are: sensilla trichodea; s.

The antennal sensory organs of honey bees have been studied by many researchers in the past. In most instances their work was confined to readily identifiable cuticular sensory structures such as the pore plate organ (Figs. 1, 3) and several types of hair-like sensilla (Fig. 1). The total number of receptors on a honey bee antennae is roughly 13,000 of

The gustatory sensilla on the endophytic ovipositor of Odonata
Arthropod Structure & Development, 2013The present paper aims at describing the fine structure of coeloconic sensilla located on the cutting valves of the endophytic ovipositor of two Odonata species, the anisopteran Aeshna cyanea (Aeshnidae) and the zygopteran Ischnura elegans (Coenagrionidae), by carrying out parallel investigations under SEM and TEM.

Cuticle and cuticular sensilla in Agnostina
2022Abstract The microstructure of the cuticle of several Agnostina species is described. For the first time, it has been shown that their cuticle consists of three layers: thick outer and transitional layers and a thin inner layer.

The morphology of spider sensilla II. chemoreceptors
Tissue and Cell, 1973ABSTRACT. The fine structure of Chemosensitive hair sensilla is described for a web spider ( Araneus diadematus ) and for a wolf spider ( Lycosa punctulata ). Chemosensitive hair sensilla occur on the distal segments of all extremities. Their morphological characteristics are: (I) a steeply inserted, socketed hair shaft; (2) three different lumina (C,

The ultrastructure of the tricorn sensilla of the woodlouse Porcellio scaber was investigated in cryofixed and freeze-substituted, or chemically fixed specimens. The tricorn sensilla have a foramenized triangular-shaped outer hair and bear a poreless rod-like inner hair. The conical base of the inner hair is connected to the base of the outer hair by a

Abstract On each antenna of female Aedes aegypti four types of sensilla trichodea are distinguishable: long and short, pointed-tipped ones and blunt-tipped types I and II. All types are innervated by two neurones, except the short, pointed-tipped trichodea with which only one neurone is associated.

Mechano- and Chemoreceptive Sensilla
1985Arachnids do not have antennae, but bear most of their sensory organs on their extremities. In particular the palps and first two pairs of legs carry a variety of mechano- and chemoreceptors. The basic receptor form is represented by the sensory hair or hair sensillum.

Spider joint hair sensilla: adaptation to proprioreceptive stimulation
Journal of Comparative Physiology A, 2014Adding to previous efforts towards a better understanding of the remarkable diversity of spider mechanosensitive hair sensilla, this study examines hairs of Cupiennius salei most likely serving a proprioreceptive function. At the tibia-metatarsus joint of all walking legs, there are two opposing groups of hairs ventrally on the tibia (20 hairs) and ...

Poreless sensilla with inflexible sockets
Cell and Tissue Research, 1983Poreless sensilla (np-sensilla) on the antennae of 18 species from 9 insect orders, and on the maxillary palps of Periplaneta americana were investigated using chemo- and cryofixation. The number of np-sensilla is low. Common features of these sensilla are: (a) the presence of a peg, (b) the lack of pores that lead to the dendritic outer segments (DOS),
