Development and Growth Patterns of Olfactory Sensilla in Malacostracan Crustaceans
2002Olfactory sensilla (aesthetascs) in malacostracan crustaceans have similar growth patterns. Detailed evidence in larval Carcinus maenas indicates that the medial aesthetascs are the first to be added on a new segment; more lateral aesthetascs occur later. When a new segment has received its maximum number of aesthetascs, new aesthetascs are added basal

Ultrastructure of the aesthetasc (olfactory) sensilla of the spiny lobster, Panulirus argus
Cell and Tissue Research, 1988The aesthetascs of the spiny lobster, Panulirus argus, are hair sensilla located on the lateral filaments of the antennules. Each hair is about 0.8 mm long and innervated by about 320 bipolar sensory neurons, the dendrites of which project as a bundle into the hair shaft. Each of the dendrites develops two cilia.

Abstract The antennal sensilla of male and female Pseudoperichaeta nigrolineata Walker (Diptera: Tachinidae) were studied by scanning electron microscopy. Five types of sensilla were identified on the funicle. The trichoid sensilla are most conspicuous, with a characteristic distal curvature and wall pores.

Freeze‐fracture characteristics of insect gustatory and olfactory sensilla. II. Cuticular features
Journal of Morphology, 1984AbstractThe freeze‐fracture technique has been used to obtain detailed information about cuticular constituents and outgrowths of the external skeleton of labella and antennae in the bluebottle fly Calliphora vicina and the antennae of the small moth (Yponomeuta spp.).

Insect repellents are widely used to protect against insect bites and thus prevent allergic reaction and the spread of disease. To gain insight into the mosquito's response to chemicals repellents, we investigated the interaction between the olfactory system of the mosquito Culex quinquefasciatus Say and chemical repellents using single sensillum ...

Sensilla on six olfactory organs of male Eogystia hippophaecolus (Lepidoptera: Cossidae)
Microscopy Research and Technique, 2018AbstractEogystia hippophaecolus (Hua et al.) is an important boring pest that primarily damages sea buckthorn, causing large ecological and economic damages in China. In this study, we used scanning electron microscopy to investigate the sensilla on six olfactory tissues of male E.

Tormogen cell and receptor-lymph space in insect olfactory sensilla
Cell and Tissue Research, 1978(1) The basiconic sensilla on the antennae of Calliphora resemble other insect epidermal sensilla; one or several bipolar sense cells are surrounded by three non-neural cells. (2) The apical cell membrane of the tormogen cell (one of the three accessory cells) forms microvilli coated internally with particles.

The olfactory plate organs found on the proximal segments of aphid antennae, the secondary rhinaria, were studied in apterae of the aphid Uroleucon ambrosiae. The numbers and shapes of these structures are important taxonomic characters in Aphididae, but they also show intraspecific variation within a morph.
