A quantitative study of adipokinetic hormone of the firebug, Pyrrhocoris apterus [PDF]

open access: yesJournal of Insect Physiology, 2002
The development of an enzyme-linked immunoassay (ELISA) for the adipokinetic neuropeptide hormone, Pya-AKH, from the firebug Pyrrhocoris apterus L. is described. The ELISA measures as little as 20 fmol of Pya-AKH. Tested against a range of synthetic peptides, the assay has a high sensitivity for peptides containing the C-terminal motif FTPNWamide.

Body size and mating success in Pyrrhocoris apterus (Heteroptera) [PDF]

open access: yesEuropean Journal of Entomology, 2003
The effects of body size on mating success and duration of copulation were investigated in Pyrrhocoris apterus. Under laboratory conditions relative mating success of small and large males was investigated in groups of 2 males (majority sex) : 1 female ...

Dietary cardenolides enhance growth and change the direction of the fecundity‐longevity trade‐off in milkweed bugs (Heteroptera: Lygaeinae)

open access: yesEcology and Evolution, 2021
Sequestration, that is, the accumulation of plant toxins into body tissues for defense, was predicted to incur physiological costs and may require resistance traits different from those of non‐sequestering insects.

Implications of temperature-dependent development and survival of Hemipteroseius adleri Costa, 1968 on its distribution in central Europe [PDF]

open access: yesScientific Reports
Otopheidomenidae include 30 species of parasites of insects. These mites occur in areas with warm and hot climates. The only exception is Hemipteroseius adleri, the distribution of which reaches the central European region, which is characterised by a ...

Salivary proteins potentially derived from horizontal gene transfer are critical for salivary sheath formation and other feeding processes [PDF]

open access: yesCommunications Biology
Herbivorous insects employ an array of salivary proteins to aid feeding. However, the mechanisms behind the recruitment and evolution of these genes to mediate plant-insect interactions remain poorly understood.

Morphological structure of salivary glands, alimentary canal, and Malpighian tubules in adult Eurydema spectabilis Horváth, 1882 (Heteroptera, Pentatomidae). [PDF]

open access: yesMicrosc Res Tech
In E. spectabilis, the salivary glands are divided into principal and accessory glands. Microvilli and numerous secretory granules were found in Malpighian tubules. Numerous uric acid crystals and bacteria were found in the rectum lumen. Abstract Eurydema spectabilis (Heteroptera: Pentatomidae) has a piercing‐sucking mouth type and feeds on plant sap ...

Comparative Analysis of Volatile Defensive Secretions of Three Species of Pyrrhocoridae (Insecta: Heteroptera) by Gas Chromatography-Mass Spectrometric Method. [PDF]

open access: yesPLoS ONE, 2016
The true bugs (Hemiptera: Heteroptera) have evolved a system of well-developed scent glands that produce diverse and frequently strongly odorous compounds that act mainly as chemical protection against predators.

Comparative analysis of adipokinetic hormones and their receptors in Blattodea reveals novel patterns of gene evolution

open access: yesInsect Molecular Biology, Volume 32, Issue 6, Page 615-633, December 2023., 2023
Comprehensive analysis of adipokinetic hormone gene evolution in Blattodea. Discovery of a novel group of decapeptides that are unique to Blaberoidea. Adipokinetic hormone receptor genes broadly reflect accepted blattodean relationships. Abstract Adipokinetic hormone (AKH) is a neuropeptide produced in the insect corpora cardiaca that plays an ...

The spread of satellite DNAs in euchromatin and insights into the multiple sex chromosome evolution in Hemiptera revealed by repeatome analysis of the bug Oxycarenus hyalinipennis

open access: yesInsect Molecular Biology, Volume 32, Issue 6, Page 725-737, December 2023., 2023
The genomic analysis revealed a male‐biased abundance of satellite DNAs (satDNAs) in the bug Oxycarenus hyalinipennis. The complementary chromosomal analysis by fluorescence in situ hybridization supported the notion of satDNA enrichment on the Y chromosome of the species.
