Structure, distribution and innervation of sensilla on the ovipositor of the spruce budworm Choristoneura fumiferana, and electrophysiological reponses from type II sensilla
… female spruce budworm has four types of trichoid sensilla on its ovipositor. A unique and rare type of sensillum is described. This Type II sensillum is multiporous and also has a single pore at the tip. The other sensillar types found were: Type I and III sensilla, which are short and long …

Focused orientation of campaniform sensilla on Periplaneta americana L. (Orthoptera: Blattidae) trochanters and femurs
Orientation overlap of campaniform sensilla fields suggests that depolarizations originating from each field are integrated. Intra- and inter-field functional integration is suggested by the frequency of parallel and series campaniform sensilla orientations. Although several campaniform sensilla …

Role of labellar and ovipositor taste sensilla of Drosophila suzukii in host recognition: a morpho-functional and behavioural approach.
… section is a morpho-functional study of the sensilla housed in the ovipositor of D. suzukii, the role of which is still unknown. The results show that the ovipositor of D. suzukii presents 10 single pore sensilla that respond to gustatory stimuli such as carbohydrates (sucrose, fructose and …

Odorant Responses and Courtship Behaviors Influenced by at4 Neurons in Drosophila
… are localized in a specific subset of olfactory sensilla located on the antenna called trichoid sensilla. In Drosophila there are two classes of trichoid sensilla, at1 sensilla that contain the dendrites of a single neuron that is specifically tuned to the male-specific pheromone 11-cis vaccenyl …

Comparative Morphology of Sensilla Styloconica on the Proboscis of North American Nymphalidae and Other Selected Taxa: Systematic and Ecological Considerations.
Sensilla styloconica on the proboscis of 107 species of North American and tropical butterflies were comparatively studied using the scanning electron microscope. Focus was on 76 species of North American Nymphalidae representing 45 genera and 11 subfamilies. Nomenclature for generalized and …

Evidence for the Sensory Receptor(s) of the Mounting Sex Pheromone in Two Species of Ixodid Ticks, <i>Dermacentor variabilis</i> (Say) and <i>Dermacentor andersoni</i> Stiles
<p>The foreleg claw sensilla were determined to be the receptors of the female contact sex pheromone, MSP (mounting sex pheromone), in <em>D. variabilis</em>, <em>D. andersoni</em> and<em> A. americanum</em> male ticks. In all three tick species, the claw sensilla consists of six …

Neural processing of chemosensory information from the locust legs
… The central projection of basiconic sensilla, canal sensilla and meshanoreceptors sensillum were studied by using neurobiotin backfilling and single cell recording. Results indicated that sensitivity of the prothoracic leg and its reflex are faster in comparison to the mesothoracic …

Aspects of the morphology of the ovipositor of Hylotrupes bajulus (L.) (Coleoptera: cerambycidae)
… 8 has both long tactile hairs and short trichoid sensilla. Intersegmental membrane 8/9 has no vi sible sensory receptors. Segment 9 has campaniform receptors and short trichoid sensilla. The gonostyli have several types of sensory receptors including long tactile hairs, medium trichoid ser..silla, …

Neural processing of chemosensory information from the locust ovipositor
Contact chemoreceptors (basiconic sensilla) located on the ovipositor and genital segments of the locust serve to control the chemical features of the substrate before and during oviposition. They occur dispersed and also crowded in fields between mechanosensory exteroceptors sensitive to touch or …

The sensory mediation of symbiosis between hyperiid amphipods and salps
… of the distribution and morphology of sensilla on the dorsal surface of the exoskeleton and antennules of the three genera of hyperiids with speculation on their functions. The ultrastructure of the aesthetasc. sensilla of Vibilia sp. was determined for comparison with other crustacean …

A NOVEL ROLE FOR CYTOCHROME P450 G 35 (CYP4G35) IN ODOR PROCESSING IN AEDES AEGYPTI MOSQUITOES
… palps, and proboscis. These appendages have sensilla hairs covering their exterior structure. The sensilla hair houses many chemoreceptors, including odorant, ionotropic, and gustatory receptors. The volatile odorants enter the sensilla lymph through pores to bind to the receptors. …

The role of olfaction in host-finding by two specialist predators of hemlock woolly adelgid
… for the presence and abundance of olfactory sensilla. The second experiment was designed to detect a behavioral response by the predators following exposure to host volatile compounds. The final experiment involved identifying compounds emitted from eastern hemlock, and the affect of …

Fine structure of the ovipositor and studies of feeding and oviposition site selection by the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)
… present. Two basic types were found: trichoid sensilla and basiconic sensilla. These receptors are believed to function as mechano- and chemoreceptors to evaluate the suitability of a host plant for feeding, oviposition, and subsequent larval development. Two greenhouse experiments were …

A Novel Role for Odorant Binding Proteins in Deactivation of Drosophila Olfactory Neurons

Plant-insect interactions between female dogwood borer and apple
… male and female dogwood borer antennae and their sensilla were examined using light and scanning electron microscopy to characterize, measure and compare the types, number, and distribution of sensilla. Although the general shape and size of male and female antennae were similar, those from …
