Steroid receptor coactivator TAIMAN is a new modulator of insect circadian clock. [PDF]
PLoS Genetics, 2023 TAIMAN (TAI), the only insect ortholog of mammalian Steroid Receptor Coactivators (SRCs), is a critical modulator of ecdysone and juvenile hormone (JH) signaling pathways, which govern insect development and reproduction.

Comparative Analysis of Three Trypanosomatid Catalases of Different Origin [PDF]
Antioxidants, 2021 Most trypanosomatid flagellates do not have catalase. In the evolution of this group, the gene encoding catalase has been independently acquired at least three times from three different bacterial groups.

Habitat Temperatures of the Red Firebug, Pyrrhocoris apterus: The Value of Small-Scale Climate Data Measurement [PDF]
Insects, 2023 Ambient temperature is a main parameter that determines the thriving and propagation of ectothermic insects. It affects egg and larval development as well as adults’ survival and successful overwintering.

Light and Temperature Synchronizes Locomotor Activity in the Linden Bug, Pyrrhocoris apterus
Frontiers in Physiology, 2020 Circadian clocks are synchronized with the external environment by light and temperature. The effect of these cues on behavior is well-characterized in Drosophila, however, little is known about synchronization in non-model insect species.

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.

Effect of Male Body Size on Female Reproduction in Pyrrhocoris apterus (L.) (Heteroptera, Pyrrhocoridae) [PDF]
Insects, 2022 Females and males of the abundant heteropteran species Pyrrhocoris apterus (L.) mate with the larger of the available partners. The male benefits from copulation with a large female, which is more productive than a small female.

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 ...

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