Thoracic scent efferent system of Pentatomoidea (Hemiptera: Heteroptera): a review of terminology

  title={Thoracic scent efferent system of Pentatomoidea (Hemiptera: Heteroptera): a review of terminology},
  author={Petr Kment and Jitka Vil{\'i}mov{\'a}},
The terminology used for structures constituing the thoracic scent efferent system is reviewed and discussed, with the emphasis on the Pentatomoidea. The most suitable terms are selected and suggested for a general use, i.e., scent gland system, metathoracic scent apparatus, thoracic scent efferent system, internal scent efferent system, internal orifice, vestibule, vestibular furrows, external scent efferent system, ostiolar plate, metepimeral pseudosuture, ostiole, ostiolar groove…

Comparative morphology of the odoriferous system in three predatory stink bugs (Heteroptera: Asopinae)

There are differences in physiological function of the odoriferous system and the volatile compounds produced by the secretory cells, which may indicate variation in defensive behavior of these species.

Scanning the Hyocephalidae: details of their external morphology with respect to phylogenetic relationships within Eutrichophora (Hemiptera: Heteroptera)

The morphology of trichobothria in Hyocephalidae may suggest either their closer relationship to Lygaeoidesa + Pyrrhocoroidea than to Coreoidea, or a parallel evolution of the open bothrium with trichome in Eutrichophora.

The external scent efferent system of selected European true bugs (Heteroptera): a biomimetic inspiration for passive, unidirectional fluid transport

Video analysis of conducted fluid-flow experiments showed that bug-inspired, artificial scent fluid channels can indeed transport different fluids passively in one direction, while halting the fluid movement in the opposite direction.

Revision of Lineostethus (Heteroptera: Pentatomidae: Discocephalini)

The last review of the genus, from the 1980’s, focused on the genital morphology and failed to provide updated descriptions or a key to species and here the generic description of Lineostethus is updated and its known species and its new species are described.

Interaction between predatory and phytophagous stink bugs (Heteroptera: Pentatomidae) promoted by secretion of scent glands

The secretion of the scent gland of P. nigrispinus and E. heros produces repellent and irritant effects between species and between sexes of the same species, supporting the defensive function of these compounds.



Thoracic scent efferent system of the Tessaratomidae sensu lato (Hemiptera: Heteroptera: Pentatomoidea) with implication to the phylogeny of the family

The results of the cladistic analyses further support the monophyly of Dinidoridae + Tessaratomidae sensu lato and that of Tessaratombomidae Sensu stricto, while the relationships of Oncomerinae and TessaratOMidae sensU stricto as well as the relationships among the family-group taxa within Tessaratomers sensu stricta need further studies.

The metathoracic scent gland system in Hydrocorisae (Heteroptera: Nepomorpha)

It is considered that the facts now known on metathoracic scent gland structure and function accord well with the hypothesis that Hydrocorisae constitute a polyphyletic assemblage.


The function of the scent-gland apparatus was studied in nymphs and adults of 3 Alydidae: Megalotomus quinquespinosus (Say), Alydus eurinus (Say, and AlydUS pilosulus (Herrich-Schaeffer) and there was a reduction in the glandular end apparatus with aging.

Metathoracic glands and associated evaporatory structures in Reduvioidea (Heteroptera: Cimicomorpha), with observation on the mode of function of the metacoxal comb

Two fundamentally different mechanisms to spread secretions of the metathoracic gland - atomization and evaporation - are present in Reduviidae.

Scanning Electron Microscopic and Chemical Study of the Metathoracic Scent Glands System of Rhaphigaster nebulosa (Poda, 1761) (Heteroptera: Pentatomidae)

The metathoracic scent glands (MTGs) system of adult Rhaphigaster nebulosa was described by electron microscopy and secretion from them was analysed by a combination of gas chromatography and mass spectrometry.

Morphology and chemical composition of metathoracic scent glands in Dolycoris baccarum (Linnaeus, 1758) (Heteroptera: Pentatomidae)

The morphology of the MTG of Dolycoris baccarum (Linnaeus 1758) was studied and the biological functions of the glandular secretions were discussed and the compounds identified were investigated.

Isoprenoids from metathoracic scent gland of cotton seed bug,Oxycarenus hyalinipennis (Costa) (Heteroptera: Lygaeidae)

Observations made during gland reservoir filling indicate that the secretion from the gland tubules undergoes a dramatic change in composition within the first day or so after adult emergence, and it is an interesting feature of the metathoracic system in Oxycarenus that oct-2-enyl acetate persists together with oct- 2-enal as a major component in the scent oil in the median reservoir.

The scent glands and their chemicals in the aposematic cotton harlequin bug, Tectocoris diophthalmus (heteroptera: Scutelleridae)

In describing differences in morphology, developmental fate and secretion composition in the scent glands of the cotton harlequin bug Tectocoris diophthalmus we have sought to extend comparative

Revision of the Cyrtocoridae (hemiptera : Pentatomoidea)

Other features, including those of the nymphs' tergal plates, the venation of both wings, and the placement of the abdominal trichobothria, confirm the familyrank status of Cyrtocoridae.
