Morphological Disparity of the Mouthparts in Polyphagous Species of Largidae (Heteroptera: Pentatomomorpha: Pyrrhocoroidea) Reveals Feeding Specialization

  title={Morphological Disparity of the Mouthparts in Polyphagous Species of Largidae (Heteroptera: Pentatomomorpha: Pyrrhocoroidea) Reveals Feeding Specialization},
  author={Yan Wang and Jolanta Brożek and Wu Dai},
Mouthpart structures were observed in four species of Largidae using scanning electron microscopy to investigate their morphological disparity, and linked to changes in feeding specialization. The examined species are pests that feed mainly on seeds and plant sap of forbs, shrubs, and trees. Their external mouthparts are described in detail for the first time herein. The cone-like labrum and four-segmented tube-like labium are shorter in Physopelta species than in Macrocheraia grandis (Grey…

Comparative Morphology of the Mouthparts in Three Predatory Stink Bugs (Heteroptera: Asopinae) Reveals Feeding Specialization of Stylets and Sensilla
The detailed structure of the predatory pentatomid’s mouthparts shown in this study can provide more data for the morphological differentiation of the mouthparts in the future.
Unique Fine Morphology of Mouthparts in Haematoloecha nigrorufa (Stål) (Hemiptera: Reduviidae) Adapted to Millipede Feeding
In this study, fine morphology of the mouthparts and feeding performance of Haematoloecha nigrorufa was observed and described in detail for the first time, providing insight into the structure and function of the Mouthparts adapted for millipede feeding.
Ultrastructural Variations of Antennae and Labia Are Associated with Feeding Habit Shifts in Stink Bugs (Heteroptera: Pentatomidae)
A set of key ultrastructural characteristics closely associated with feeding habit transition in stink bugs are identified and discussed and will facilitate future studies on adaptive evolution of feeding habits, utilization, and population control of economic species in Pentatomidae as well as in other heteropteran lineages.
First description and comparison of the morphological and ultramicro characteristics of the antennal sensilla of two fir longhorn beetles
The observed difference in the sensillum distribution and function between the two fir longhorn beetles will greatly facilitate the design of better semiochemical control methods of these insect pests.
How Does the Intricate Mouthpart Apparatus Coordinate for Feeding in the Hemimetabolous Insect Pest Erthesina fullo?
The fine structure of the mouthparts is examined with scanning electron microscopy, and feeding performance are observed directly under laboratory conditions for the first time, to better understand the feeding mechanism of Erthesina fullo.
New functionally ultrastructural details of the honey bee stinger tip: serrated edge and pitted surface
It is hypothesized that the tips of the stinger lancets are not smooth; their edges are serrated and their surface contains numerous pits, which can cause more extensive tissue damage in victims and cut up more cell membranes than if their surfaces were smooth.


Fine structure of mouthparts and feeding performance of Pyrrhocoris sibiricus Kuschakevich with remarks on the specialization of sensilla and stylets for seed feeding
The structure and function of the mouthparts are adapted for the seed feeding habits of the temperate firebug, and sensilla trichodea are most abundant.
Morphology, arrangement and classification of sensilla on the apical segment of labium in Peiratinae (Hemiptera: Heteroptera: Reduviidae)
Sensation structures on the apical segment of the labium in representatives of the subfamily Peiratinae (Heteroptera: Reduviidae), using the scanning electron microscope, are described, finding four new types of sensilla.
Morphological diversity of the labial sensilla of phytophagous and predatory Pentatomidae (Hemiptera: Heteroptera), with reference to their possible functions.
Sensory structure on the labial surface of five genera of Pentatomidae belonging to two subfamilies i.e. Asopinae and Pentatominae have been studied using Scanning Electron Microscopy to morphologically characterize and compare the sensory structures present on the laboratoryium.
Structure and Sensilla of the Mouthparts of the Spotted Lanternfly Lycorma delicatula (Hemiptera: Fulgoromorpha: Fulgoridae), a Polyphagous Invasive Planthopper
Morphological similarities in the interlocking mechanism of the stylets suggest a relationship between Fulgoromorpha and Heteroptera and the proposed taxonomic and functional significance of the sensilla are discussed.
Comparative Analysis and Systematic Mapping of the Labial Sensilla in the Nepomorpha (Heteroptera: Insecta)
The new apomorphical characters have been established for the labial sensilla in the Nepomorpha.
Morphology and distribution of the external labial sensilla in Fulgoromorpha (Insecta: Hemiptera)
A gustatory function is provided for several chemoreceptive labial sensilla, as in the antennal flagellum sensilla in some other Hemiptera, which represents a more recently evolved function for the planthopper labium.
Sensillary morphology on the rostral apex and their possible role in prey location behaviour of the carnivorous stinkbug, Eocanthecona furcellata (Wolff) (Heteroptera: Pentatomidae)
Three new and unique types of sensilla were discovered in Eocanthecona furcellata, the carnivorous heteropteran, and possible functions of individual receptors are suggested on morphological grounds.
Title: A comparison of the external morphology and functions of labial tip sensilla in semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha)
This study provides new data on the morphology and distribution of the labial tip sensilla of 41 species of 20 gerromorphan (sub)families (Heteroptera: Gerromorpha) obtained using a scanning electron microscope and records one putative diagnostic character for Macroveliidae + Veliidae, two families that are otherwise not considered sister groups.
