Pre-diapause mating and overwintering of fertilized adult females: New aspects of the life cycle of the wing-polymorphic bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2010
New aspects of the life-cycle of the flightless wing-polymorphic bug Pyrrhocoris apterus (L.) are described. It was found that 1.1-14.9% of the adult females of P. apterus in 11 samples collected from 4 populations in the South Bohemia had mated prior to

Predator dependent mimetic complexes: Do passerine birds avoid Central European red-and-black Heteroptera?

open access: yesEuropean Journal of Entomology, 2010
True bugs are generally considered to be well protected against bird predation. Sympatric species that have similar warning coloration are supposed to form a functional Müllerian mimetic complex avoided by visually oriented avian predators.

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

open access: yesInsect Science, EarlyView.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

Physiology of cold-acclimation in non-diapausing adults of Pyrrhocoris apterus (Heteroptera)

open access: yesEuropean Journal of Entomology, 2002
Chill tolerance (time of survival at -5°C) increased in non-diapausing (reproducing) adults of Pyrrhocoris apterus after a gradual, 4-week-long decrease in ambient temperature from 25° to 0°C.

Latitudinal gradient in response of wing polymorphism to photoperiod in a flightless bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2001
The aim of this study was to determine if there is a latitudinal gradient in the photoperiodic regulation of wing dimorphism in the flightless bug, Pyrrhocoris apterus (L.).

Native insect species should be selected for classroom rearings

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 1-10, January 2026.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Seasonal activity-profiles of enzymes involved in cryoprotectant biosynthesis in Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2008
The activities of three enzymes involved in polyol biosynthesis (aldose reductase, AR; ketose reductase, KR; and polyol dehydrogenase, PDH) were studied in adult females of the linden bug, Pyrrhocoris apterus, collected from the field during 2005/2006 ...
