The maxillary palp of Drosophila : ultrastructure and physiology depends on the lozenge gene

Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 1997
The ultrastructure and physiology of the maxillary palp of Drosophila melanogaster have been studied in wild-type and lozenge mutants. Olfactory physiology in the maxillary palp is shown to depend upon the lozenge(lz) gene. Reduced response amplitudes were recorded for all odorants tested, and the physiological defect was shown to map to the lz locus ...

The maxillary palps of Tephritidae are selectively tuned to food volatiles and diverge with ecology [PDF]

Journal of Insect Physiology
The maxillary palp is an auxiliary olfactory organ in insects, which, different from the antennae, is equipped with only a few olfactory sensory neuron (OSN) types. We postulated that these derived mouthpart structures, positioned at the base of the proboscis, may be particularly important in mediating feeding behaviors. As feeding is spatio-temporally

Ultrastructure of the Olfactory Sensilla across the Antennae and Maxillary Palps of Bactrocera dorsalis (Diptera: Tephritidae) [PDF]

Insects, 2021
The sensilla on the antennae and maxillary palps are the most important olfactory organs, via which the insect can perceive the semiochemicals to adjust their host seeking and oviposition behaviors. The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is a major agricultural quarantine pest infesting more than 250 different ...

Sensilla on antenna and maxillary palp of Neoceratitis asiatica (Diptera: Tephritidae)

Micron, 2020
Neoceratitis asiatica (Diptera: Tephritidae) is a disastrous pest for wolfberry production in China. In our preliminary field trapping experiment, both female and male N. asiatica adults were captured by male-produced sex attractant. To provide a solid background for studying mechanism of olfaction, the sensilla of antenna and maxillary palp of N ...

THE FUNCTIONS OF THE MAXILLARY PALPS OF ACRIDIDAE (ORTHOPTERA)

Entomologia Experimentalis et Applicata, 1970
The functions of the maxillary palps of acridids have been investigated in experiments with Locusta migratoria migratorioides (R. & F.), Schistocerca gregaria (Forsk.) und Chorthip‐pus purallelus (Zett.). The palp makes small irregular flicking movements and more extensive rapid vibrations described as palpation.

The maxillary palp of Aedes aegypti, a model of multisensory integration

Insect Biochemistry and Molecular Biology, 2014
Female yellow-fever mosquitoes, Aedes aegypti, are obligate blood-feeders and vectors of the pathogens that cause dengue fever, yellow fever and Chikungunya. This feeding behavior concludes a series of multisensory events guiding the mosquito to its host from a distance.

Olfactory physiology in the Drosophila maxillary palp requires the visual system gene rdgB

Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 1994
We describe the kinetics of odorant response in the maxillary palp of Drosophila, and show that the rate of recovery from odorant stimulation is affected by mutation of the rdgB (retinal degeneration B) gene. We use immunocytochemistry to confirm that the rdgB gene product is expressed in the maxillary palp.

Maxillary palps can mediate taste rejection of plant allelochemicals by caterpillars

Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 1998
All caterpillars possess a pair of maxillary palps that "drum" the surface of foods during feeding. These chemosensory organs contain over 65% of a caterpillar's taste receptor cells, but their functional significance remains largely unknown. We examined their role in rejection of plant allelochemicals, using the tobacco hornworm (Manduca sexta) as a ...

Maxillary Palp: A Second Olfactory Organ of Drosophila

1994
A wide variety of animals, including many amphibians, reptiles, and mammals, have an olfactory organ and another chemosensory organ, the vomeronasal organ [1–3]. This second organ is associated with pheromone detection and the modulation of sexual behavior.
