Mouthparts of ectoparasites and host damage

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1980
SynopsisPhotographs 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, 2007
The 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

2019
An 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, 1954
IT 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, 2014
The 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.

Fluid-Feeding Mouthparts

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.

Mouthparts of adult Plodia interpunctella

2013
Die Anatomie und Morphologie der Mundwerkzeuge sowie das Vorkommen der unterschiedlichen Typen von Sensillen auf den Mundwerkzeugen von Plodia interpunctella (Pyralidae) wurden mit Hilfe von Lichtmikroskopie und Rasterelektronenmikroskopie untersucht.

Stereoscan views of some aphid mouthparts

Canadian Journal of Zoology, 1970
The 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.

Form and Function of Insect Mouthparts

2019
Insect mouthparts are modified appendages of head segments that are adapted to exploit different food sources. This chapter describes the general mouthpart morphology of Hexapoda, introduces basic feeding types in insects, and illustrates mouthpart function.
