Individual behaviour in firebugs (Pyrrhocoris apterus) [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2010
The concept of animal personalities has recently become of major interest as researchers began to wonder why animals within a given population show consistent behaviour across situations and contexts, what led to the evolution of such behavioural inflexibility and what mechanisms might underlie the phenomenon.

Red Firebug [PDF]

open access: yes, 2023
Red firebugs, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae), are true bugs with vibrant red body and wing coloration. These insects are native to central Europe, but are also found in western Siberia, southwestern Mongolia, India and northwestern ...

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

open access: yesEuropean 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 ...

Implementation of grid-connected wind energy during fault analysis using moth flame optimization with firebug swarm optimization [PDF]

open access: yes, 2023
In modern trends, the voltage profile has become increasingly critical when incorporating wind turbine energy sources because of changes in fault ride-through capabilities throughout voltage reaction.

Sexual activity in macropterous and brachypterous males of a flightless bug, Pyrrhocoris apterus (Heteroptera)

open access: yesEuropean Journal of Entomology, 2001
The long-winged (macropterous) and short-winged (brachypterous) adult males of Pyrrhocoris apterus (L.) from temperate (Czech Republic) and Mediterranean (Israel) populations were analysed for the sexual activity and the functional activity of their ...

Fine structure of mouthparts and feeding performance of Pyrrhocoris sibiricus Kuschakevich with remarks on the specialization of sensilla and stylets for seed feeding. [PDF]

open access: yesPLoS ONE, 2017
Mouthpart structure and feeding behavior in the temperate firebug, Pyrrhocoris sibiricus Kuschakevich, an important pest that feeds on seeds of leguminous and gramineous plants, are described for the first time.

Do long- and short-winged adult females of the bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) differ in lifespan and reproductive capacity?

open access: yesEuropean Journal of Entomology, 2013
In the present study we tested whether long-winged (macropterous) and short-winged (brachypterous) adult females of the firebug Pyrrhocoris apterus (L.) differ in their reproductive capacity and length of life.

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

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.

Seed preferences of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae): Are there specialized trophic populations?

open access: yesEuropean Journal of Entomology, 2011
The populations of the firebug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) in Europe exhibit three kinds of host plant associations: feeding on seeds of (1) Tilia spp. (Tiliaceae), (2) Malvaceae (s. str.), and (3) Robinia pseudacacia (Fabaceae). The
