Structural and functional aspects of sense organs on the maxillary palps of Calliphora vicina

Journal of Insect Physiology, 1976
Abstract The maxillary palps of the blowfly Calliphora vicina Robineau-Desvoidy are shown to bear, in addition to long mechanoreceptive hairs, small sensilla basiconica ccontaining three neurons. The electrical responses obtained with a simple qualitative olfactometer indicate an olfactory function.

Quantifying relative importance of maxillary palp information on the olfactory behavior of Drosophila melanogaster

Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 1994
Maxillary palps have been proposed as secondary olfactory organs, after the antennae, in Drosophila melanogaster. Our study tries to establish the quantitative importance of both organs as olfactory information mediators. Dose-response curves for three odorants: ethyl acetate, propionaldehyde and benzaldehyde were carried out for comparing olfaction in

Ultrastructural Morphology of the Antenna and Maxillary Palp ofSarcophaga tibialis(Diptera: Sarcophagidae)

Journal of Medical Entomology, 2016
A scanning electron microscopy investigation of the antenna and maxillary palp of the adult of Sarcophaga tibialis Macquart (Diptera: Sarcophagidae), a species of medical, veterinary, and forensic relevance, is presented for the first time. Adults of both sexes used in this study were obtained from larvae collected in a case of traumatic myiasis in a ...

The ultrastructure of an olfactory sensillum on the maxillary palps of Locusta migratoria (L.)

Cell and Tissue Research, 1977
The olfactory sensilla on the maxillary palp tip of Locusta migratoria (L.) resemble the surrounding contact chemoreceptors in general morphology. The perforated peg has a thicker wall than is commonly found in olfactory sensilla. The form and position of the sensilla are considered in relation of the olfactory function.

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 ...

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 ...

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.

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
