The capacity to maintain ion and water homeostasis underlies interspecific variation in Drosophila cold tolerance [PDF]

open access: yes, 2015
Many insects, including Drosophila, succumb to the physiological effects of chilling at temperatures well above those causing freezing. Low temperature causes a loss of extracellular ion and water homeostasis in such insects, and chill injuries ...

Cold hardiness of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) from central and southern Europe

open access: yesEuropean Journal of Entomology, 2000
The cold hardiness of individuals from overwintering populations of a freeze susceptible bug Pyrrhocoris apterus from central and southern Europe differed significantly.

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.

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

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.

Transcription of Leishmania major U2 small nuclear RNA gene is directed by extragenic sequences located within a tRNA-like and a tRNA-Ala gene [PDF]

open access: yes, 2016
Sequence comparisons of U2 snRNA genes and flanking regions from T. cruzi (CL Brener Non-Esmeraldo-like). Sequences from the genes located on chromosomes 23, 37 and 6 are shown. The U2 snRNA gene from chromosome 23 is presented in blue font. The position

Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.

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.).
