Cotton Stainer, Dysdercus suturellus (Herrich Schaeffer) (Insecta: Hemiptera: Pyrrhocoridae)

open access: yesEDIS, 2005
Four species of "cotton stainers," also known as "red bugs," are known from Florida. However, the most important of these is the cotton stainer, Dysdercus suturellus (Herrich- Schaeffer). Morrill (1910) stated the cotton stainer was the most destructive

Relationships between locomotor activity, oxidative damage and life span in males and females of the linden bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2013
In this study we addressed a question of whether experimental manipulations that increase life span also reduce physical activity and molecular oxidative damage.

First report on a multiple sex chromosome system (X1X2X30) and population variations in the frequency of ring bivalents in Pyrrhocoridae (Hemiptera: Heteroptera)

open access: yesEuropean Journal of Entomology, 2015
The family Pyrrhocoridae (Hemiptera: Heteroptera) is characterized by a modal diploid chromosome number of 16 (♂) ranging from 12 to 33 and simple (X0), multiple (X1X20) and neo-sex chromosome systems (neoX-neoY).

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

Cold tolerance strategy and cold hardiness of the invasive zigzag elm sawfly Aproceros leucopoda (Hymenoptera: Argidae)

open access: yesAgricultural and Forest Entomology, Volume 22, Issue 3, Page 231-237, August 2020., 2020
Abstract The invasive sawfly Aproceros leucopoda causes severe defoliation of various elm species and thus can be a major pest in forest stands and urban environments. The overwintering biology of A. leucopoda has not been investigated so far; therefore, the aim of this study was to determine the cold tolerance strategy and cold hardiness of ...

Biased predation could promote convergence yet maintain diversity within Müllerian mimicry rings of Oreina leaf beetles

open access: yesJournal of Evolutionary Biology, Volume 33, Issue 7, Page 887-898, July 2020., 2020
Blue tits select for convergence on either blue or green morphs of chemically defended Oreina leaf beetles around the Alps, forming striking Müllerian mimicry rings. Abstract Müllerian mimicry is a classic example of adaptation, yet Müller's original theory does not account for the diversity often observed in mimicry rings. Here, we aimed to assess how

The Complete Mitogenome of Pyrrhocoris tibialis (Hemiptera: Pyrrhocoridae) and Phylogenetic Implications. [PDF]

open access: yesGenes (Basel), 2019
We determined the complete mitogenome of Pyrrhocoris tibialis (Hemiptera: Heteroptera: Pyrrhocoridae) to better understand the diversity and phylogeny within Pentatomomorpha, which is the second largest infra-order of Heteroptera. Gene content, gene arrangement, nucleotide composition, codon usage, ribosomal RNA (rRNA) structures, and sequences of the ...
