Electrophysiological responses of receptor neurons in mosquito maxillary palp sensilla to carbon dioxide

Journal of Comparative Physiology A, 1995
Sensilla basiconica on the maxillary palps of female Aedes aegypti contain a receptor neuron which produces a phasic-tonic pattern of action potential response to low concentrations (150-300 ppm) of carbon dioxide (CO2), a stimulus known to be involved with host seeking behavior.

The maxillary palp organs of a wood‐boring beetle, Melittomma sericeum (coleoptera, lymexylonidae)

Journal of Morphology, 1975
AbstractThe complex and conspicuous basket‐like structure attached to the third segment of each maxillary palp of Melittomma sericeum males is densely covered with tactile hairs on its outer or convex surface and with thinwalled chemoreceptors on its inner or concave surface. In a living male the structure is highly mobile and is extended laterally and

Ultrastructure and distribution of sensilla on the maxillary and labial palps ofChlorophorus caragana(Coleoptera: Cerambycidae)

Journal of Morphology, 2018
AbstractChlorophorus caraganais a species of long‐horned beetle that damagesCaragana davazamciiSancz. (Fabales: Papilionaceae) bushes in desert areas in China. The beetles cause substantial damage to local forestry plantations and the environment. Sensilla on the maxillary and labial palps of coleopterans a allow the insects to recognize their host ...

Maxillary Palp Gustatory Receptors Mediate Aphid Corpses Avoidance in Harmonia Axyridis

Journal of Insect Physiology
The ladybird Harmonia axyridis is an important predatory natural enemy with a broad dietary spectrum and few avoided food sources. Nevertheless, it shows avoidance behavior toward aphid corpses, likely to minimize the risk of pathogen infection in the wild.

Sensilla on the maxillary palps of Helicoverpa armigera caterpillars: in search of the CO2-receptor

Tissue and Cell, 1996
The ultrastructure of sensilla on the maxillary palps of Helicoverpa armigera caterpillars has been investigated in order ot find candidates for CO(2)-receptors. The following sensilla are found on the palps: a) 8 chemosensory pegs at the tip; b), a large distal pore plate; c), a smaller proximal pore plate; d), a digitiform organ; e), a campaniform ...

The significance of palpation by the maxillary palps of Locusta migratoria (L): an electrophysiological and behavioural study

Journal of Experimental Biology, 1976
ABSTRACT Palpation increases the amount of sensory input reaching the central nervous system compared with that obtained from sustained contact but that increase is not essential to allow discrimination. During a meal on favoured food, phagostimulatory input from the palps is not needed to drive feeding. When less favoured

The structure of the terminal sensilla on the maxillary palps of Locusta migratoria (L.), and changes associated with moulting

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1971
The basic structure of the terminal sensilla of Locusta migratoria resembles that of Schistocerca gregaria. There are commonly six or ten neurons whose dendrites extend almost to the opening of the peg. Proximally the dendrites are clothed by a neurilemma cell which also encloses a basal cavity through which their ciliary region passes.

Ultrastructure of sensilla on the maxillary and labial palps of the adult Xylotrechus grayii (Coleoptera: Cerambycidae)

Microscopy Research and Technique, 2018
AbstractThe longhorn beetle, Xylotrechus grayii (White, 1855), is a serious woodborer pest of many economic and medicinal plants. The maxillary and labial palps of X. grayii adults are strongly involved in mating and host selection behaviors. To further develop control strategies of the pest, sensilla on the palps were studied with scanning and ...

The fine structure of the terminal sensilla on the maxillary palps of Schistocerca gregaria (Forsk�l) (Orthoptera, Acrididae)

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1969
The fine structure of the terminal sensilla on the maxillary palps of Schistocerca gregaria has been investigated. Most organules include six neurons with dendrites extending to the tip of the cuticular peg, the opening of which is controlled so that the dendrites are not always exposed. The neurons are isolated from each other by a neurilemma cell and

Scanning Electron Microscopy of Blaberus Giganteus (L.) Maxillary Palp Sensilla

Proceedings, annual meeting, Electron Microscopy Society of America, 1976
The maxillary palps of B. giganteus are located on the maxillae which lie between the labrum and labium. They are modified appendages used in feeding. Each appendage bears 5 segments, the most distal of which contains the palp organ or sensory pad (Fig. 1). The maxillary palps were fixed in 2.5% glutaraldehyde in 0.05 M sodium cacodylate buffer (pH 7.1)
