Mouthparts of flower-visiting insects
Arthropod Structure and Development, 2005This review deals with the morphology and function of adult insect mouthparts modified to feed on nectar, pollen or petals. Specialization to nectar-feeding is evident in formation of proboscides of various lengths and designs. Proboscides of many Hymenoptera and Diptera function according to adhesion mechanisms that load nectar onto extensible apical ...

The mouthparts of the Aradidae (Insecta: Hemiptera: Heteroptera)
Arthropod Structure & Development, 2022The flat bugs, Aradidae, have exceptionally long piercing-sucking stylets coiled up at rest in the anterior part of the head. Previous studies suggested that the majority of aradids can be divided into two groups by the direction of stylet coiling, clockwise or anticlockwise.

Mouthparts of ectoparasites and host damage
Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1980SynopsisPhotographs were displayed of the mouthparts of some important arthropod parasites of British livestock as viewed with a scanning electron microscope. Ectoparasites included in the demonstration were Damalinia ovis, the body louse of sheep; Haematopinus eurysternus, the short-nosed cattle louse; Ceratophyllus gallinae, the hen flea; Melophagus ...

The mouthparts of cockroaches (Blattodea)
Entomological Review, 2007The structure of the mouthparts was studied in 24 species representing 10 families and 4 suborders of cockroaches. The details of the labrum, mandibles, maxillae, labium, and hypopharynx, characteristic of different suborders of Blattodea and some families of Blaberoidea, were revealed.

Structure and Evolution of Mouthparts in Coleoptera
2019An unusually broad food spectrum has likely played an important role in the enormous diversification of Coleoptera (ca. 400,000 spp.). Nevertheless, the structure and configuration of the mouthparts are mostly conservative. Archostemata, often addressed as ancestral, are characterized by a trend towards limited food uptake in the adult stage, whereas ...

Hardness of Arthropod Mouthparts
Nature, 1954IT is well known that many insects are able to bore through packing materials, including metal foils, used for wrapping foodstuffs and other commodities. During an attempt to develop a physical barrier that would be resistant to penetration by insects, the hardness of the mouthparts of a number of insect pests was determined.

Mouthpart separation does not impede butterfly feeding
Arthropod Structure & Development, 2014The functionality of butterfly mouthparts (proboscis) plays an important role in pollination systems, which is driven by the reward of nectar. Proboscis functionality has been assumed to require action of the sucking pump in the butterfly's head coupled with the straw-like structure.

Mouthparts of Megaselia scalaris (Loew) (Diptera: Phoridae)
Micron, 2003Mouthparts of adult Megaselia scalaris (Loew), a fly species of medical importance, were examined using scanning electron microscopy. Sexual dimorphism of the labellum was observed in the mouthpart structures of this species. The labella of males were clothed with a dense covering of microtrichia, but these were found to be entirely absent from the ...

2019
The mouthparts of most specialized fluid-feeding insects consist of more or less elongated components forming a proboscis. Functional types of mouthparts evolved as adaptations to particular food sources. Characteristic feeding techniques are used which are based on a combination of capillarity and a pressure gradient created by sucking pumps.

Stereoscan views of some aphid mouthparts
Canadian Journal of Zoology, 1970The mouthparts, particularly the probosces of two aphid species, Myzus persicae (Sulzer) and Macrosiphum euphorbiae (Thomas), are compared with the use of the scanning electron microscope. The details of the setae on the terminal segments of the winged and wingless morphs are compared.
