Chromosomal divergence and evolutionary inferences in Pentatomomorpha infraorder (Hemiptera, Heteroptera) based on the chromosomal location of ribosomal genes. [PDF]

open access: yesPLoS ONE, 2020
With the objective of assisting in the understanding of the chromosome evolution of Pentatomomorpha and in the quest to understand how the genome organizes/reorganizes for the chromosomal position of the 45S rDNA in this infraorder, we analyzed 15 ...

What determines the occurrence of fertilized females in hibernating populations of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) in Central Europe?

open access: yesEuropean Journal of Entomology, 2020
The current climate warming is associated with the development of a second generation in populations of species such as Pyrrhocoris apterus (L.) (Heteroptera: Pyrrhocoridae), which, in Central Europe, were univoltine in the 1980s.

Composition and function of the microbiotas in the different parts of the midgut of Pyrrhocoris sibiricus (Hemiptera: Pyrrhocoridae) revealed using high-throughput sequencing of 16S rRNA

open access: yesEuropean Journal of Entomology, 2020
In pyrrhocorids, digestion of food occurs mainly in the midgut, which is divided into four parts (M1-M4), and takes between three and four days. Food is retained in M1 for about 5 h and passes quickly through M4.

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.

Convergent photoperiodic plasticity in developmental rate in two species of insects with widely different thermal phenotypes

open access: yesEuropean Journal of Entomology, 2018
Growth and development rates in many insects are affected by photoperiod, which enables insects to synchronize their life histories with seasonal events, but this aspect of insect photoperiodism remains understudied.
