Divergent Evolutionary Pressures Shape Olfactory Sensitivity of the Maxillary Palps in Tephritidae Fruit Flies [PDF]

Ecology and Evolution
Olfaction is a rapidly evolving sense. Given its diverse functions, from finding ecological niches to selection of mates, we hypothesized that olfaction is subjected to divergent evolutionary pressures.

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.

Rapid degeneration of Drosophila olfactory neurons in Orco mutant maxillary palps. [PDF]

MicroPubl Biol, 2021
The odorant receptor co-receptor Orco forms ligand-gated ion channels with odorant receptors (ORs) tuned to specific odors; Orco is required for trafficking of these complexes to the dendrites of olfactory neurons (Larsson et. al., 2004). Mutation of the Orco gene not only abolishes olfactory neuron activity but has also revealed potential new roles ...

The Expression of Chemosensory Genes in Male Maxillary Palps of Anopheles coluzzii (Diptera: Culicidae) and An. quadriannulatus. [PDF]

J Med Entomol, 2021
AbstractBecause of its importance as a malaria vector, Anopheles coluzzii’s Coetzee & Wilkerson olfactory system has been studied extensively. Among this work is a series of studies comparing the expression of chemosensory genes in olfactory organs in females and/or males of these species.

Sensillar Ultrastructure of the Antennae and Maxillary Palps of the Warble Fly Oestromyia leporina (Pallas, 1778) (Diptera: Oestridae) [PDF]

Insects
Despite the development of molecular techniques, morphological phylogeny still remains integral in underpinning the relationship between some clades of Calyptratae, especially the ones with fast radiation, such as those in Oestridae (Diptera: Brachycera),

Morphology and distribution of sensilla on the antennae and mouthparts of adult Monochamus saltuarius Gebler (Coleoptera: Cerambycidae) [PDF]

Frontiers in Insect Science
Monochamus saltuarius is an important wood-boring pest of forests and a vector insect for the transmission of Bursaphelenchus xylophilus in China and other East Asian regions. To gain insight into the Mo. saltuarius olfactory system, we characterized the

Gravid Anopheles stephensi Detects Indole for Oviposition Despite the Ablation of Antennae and Maxillary Palps [PDF]

Insects
Oviposition site selection is critical for mosquito population dynamics. Gravid mosquitoes rely on chemical cues to identify suitable breeding habitats.

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 sensilla on antennae and maxillary palps in three Mesembrinellidae species [PDF]

Revista Chilena de Historia Natural, 2018
Background Having the right identification is essential in the field of entomology. The scanning electron microscopy allows rapid and accurate identification of different species of flies since a better visualization of the external morphology of ...
