The antennules of decapod crustaceans are covered with thousands of chemosensilla that mediate odor discrimination and orientation behaviors. Most studies on chemoreception in decapods have focused on the prominent aesthetasc sensilla. However, previous behavioral studies on lobsters following selective sensillar ablation have revealed that input from nonaesthetasc antennular chemosensilla is s...

Food selection behavior of lepidopteran larvae is predominantly governed by the activation of taste neurons present in two sensilla styloconica located on the galea of the maxilla. In this study, we present the ultrastructure of the sensilla styloconica and the central projection pattern of their associated receptor neurons in larvae of the heliothine moth, Helicoverpa armigera. By means of lig...

In this thesis, the neurobiology of mechanoreceptive sensilla on the pectines of the scorpion Pandinus cavimanus was examined. The morphology of the pectines, the innervation and morphology of the sensilla as well as their response characteristics were analyzed. Based on the neurobiological results, mechanoreceptive bristles of arthropods were characterized from a technical point of view. A bio...

Two new species of free-living marine nematodes, Odontophora odontophoroides sp. nov. and Parabathylaimus jare nov., are described from the coastal sand Langhovde, Lützow-Holm Bay, Dronning Maud Land, Antarctica. is only in Bütschli, 1874 that has bicuspidate odontia. similar to Odontophoroides Boucher Helléouët, 1977 Synodontium Cobb, 1920 having odontia, but differs a didelphic reproductive s...

Mosquitoes are highly dependent on their olfactory system for, e.g. host location and identification of nectar-feeding and oviposition sites. Odours are detected by olfactory receptor neurons (ORNs) housed in hair-shaped structures, sensilla, on the antennae and maxillary palps. In order to unravel the function of the olfactory system in the yellow fever vector, Aedes aegypti, we performed sing...

Relatively little is still known about the function, types and location of cercal sensory systems. This system detects and encodes different sensory modalities: wind, touch and gustatory. It is focused on fine structure and distribution of various types of cercal sensilla in the desert locust were investigated with scanning electron microscope and neuroanatomical techniques. Two types of sensor...

We used single-sensillum recordings to characterize male Heliothis subflexa antennal olfactory receptor neuron physiology in response to compounds related to their sex pheromone. The recordings were then followed by cobalt staining in order to trace the neurons' axons to their glomerular destinations in the antennal lobe. Receptor neurons responding to the major pheromone component, (Z)-11-hexa...

Antennal sensory units in nymphs and adults of the spotted Lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoromorpha: Fulgoridae), an economically important plant pest, are studied with scanning electron microscopy. Sensilla trichodea / chaetica type recognition is based on their external morphology and ratio of their size to diameter. The flagellum Bourgoin's organ is a complex sensory ...

Relatively little is still known about the sense of taste, or contact chemoreception, compared with other sensory modalities, despite its importance to many aspects of animal behaviour. The central projections of the sensory neurons from bimodal contact chemoreceptors (basiconic sensilla) were compared with those from mechanosensory tactile hairs located on similar regions of the middle leg of ...
