Characterization of Anopheles stephensi Odorant Receptor 8, an Abundant Component of the Mouthpart Chemosensory Transcriptome

Insects, 2021
Several mosquito species within the genus Anopheles are vectors for human malaria, and the spread of this disease is driven by the propensity of certain species to feed preferentially on humans.

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil. [PDF]

Insect Mol Biol
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Ultramorphological Comparison of Proboscis and Associated Sensilla of Scotogramma trifolii and Protoschinia scutosa (Lepidoptera: Noctuidae)

Insects, 2021
The proboscis is an important feeding organ for the glossatan moths, mainly adapted to the flower and non-flower visiting habits. The clover cutworm, Scotogramma trifolii Rottemberg, and the spotted clover moth, Protoschinia scutosa (Denis ...

The Mouthparts of Female Blood-Feeding Frog-Biting Midges (Corethrellidae, Diptera)

Insects, 2023
Females of frog-biting midges (Corethrellidae) obtain their blood meals from male calling frogs. While the morphology of the feeding apparatus is well studied in hematophagous Diptera that impact humans, frog-biting midges have received far less ...

evolution of the mouthparts of insects

International journal of health sciences, 2021
We contrasted the expression patterns of several developmentally important genes in insects with mandibulate or stylate-haustellate mouthparts in order to better comprehend both the development and evolution of insect mouthparts. We found no major breaks in the evolution of mouthparts, but six in epochs with numerous innovations and few extinctions ...

Unique Fine Morphology of Mouthparts in Haematoloecha nigrorufa (Stål) (Hemiptera: Reduviidae) Adapted to Millipede Feeding

Insects, 2020
Millipede assassin bugs are a diverse group of specialized millipede predators. However, the feeding behavior of Ectrichodiinae remains poorly known, especially how the mouthpart structures relate to various functions in feeding.

Tooth row variation in tadpoles of Dendropsophus labialis (Anura: Hylidae: Dendropsophini) and the evolution of oral morphology in the genus

Caldasia, 2018
Labial tooth row variation was assessed in Dendropsophus labialis tadpoles from the Cordillera Oriental in Colombia. The presence of a second anterior labial tooth row was detected, showing thus a labial tooth row formula of 2/2.
