Mating activity of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) in nature [PDF]

European Journal of Entomology, 2019
The mating behaviour of Pyrrhocoris apterus in the laboratory is well studied, but little is known about it under natural conditions. In natural populations in Central Europe, overwintered adults start copulating in March and continue until their death ...

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

Journal 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.

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

European 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 ...

Stunning Intricacies of RNA Editing Complexes RECC, RESC, and REH2C: Functional Organization, Developmental Regulation, and Evolutionary History in Kinetoplastid Protists. [PDF]

Wiley Interdiscip Rev RNA
U‐indel RNA editing targets mRNA:gRNA duplexes through three key complexes that collectively govern assembly, specificity, catalysis, and developmental regulation. Modern tools, including artificial intelligence, analyze the organization, dynamics, and evolution of the remarkable holo‐editosome, opening new avenues in RNA biology and therapy.

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal. [PDF]

Ecol Evol
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

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

Insect 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

Insect 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.

Complete metamorphosis and microbiota turnover in insects

Molecular Ecology, Volume 32, Issue 23, Page 6543-6551, December 2023., 2023
Abstract The insects constitute the majority of animal diversity. Most insects are holometabolous: during complete metamorphosis their bodies are radically reorganized. This reorganization poses a significant challenge to the gut microbiota, as the gut is replaced during pupation, a process that does not occur in hemimetabolous insects.

Cell Cycle-Dependent Flagellar Disassembly in a Firebug Trypanosomatid Leptomonas pyrrhocoris

mBio, 2019
Current understanding of flagellum/cilium length regulation focuses on a few model organisms with flagella of uniform length. Leptomonas pyrrhocoris is a monoxenous trypanosomatid parasite of firebugs. When cultivated in vitro, L.

A review to the methods of personality measurements in wild animals 野生动物个性测量方法的综述

Wildlife Letters, Volume 1, Issue 3, Page 131-142, September 2023., 2023
One of the challenges in animal personality study is finding a suitable method to measure personality. Here, we outlined three methods (traits rating, behavioral coding, and experimentation) used in animal personality measurement. We found that traits rating was commonly used to test large‐sized animals (e.g., primates), behavioral coding was conducted
