Sex‐biased gene content is associated with sex chromosome turnover in Danaini butterflies

Molecular Ecology, Volume 33, Issue 24, December 2024.
Abstract Sex chromosomes play an outsized role in adaptation and speciation, and thus deserve particular attention in evolutionary genomics. In particular, fusions between sex chromosomes and autosomes can produce neo‐sex chromosomes, which offer important insights into the evolutionary dynamics of sex chromosomes. Here, we investigate the evolutionary

Corpus allatum volume-dependent differences in accessory gland maturation in long- and short-winged males of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2006
In the present study the temporal changes in the volume of the corpus allatum in three experimental groups of adult males (macropterous, reproductive brachypterous and diapausing brachypterous) of the flightless bug Pyrrhocoris apterus were determined ...

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

European 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.

Intra‐species quantification reveals differences in activity and sleep levels in the yellow fever mosquito, Aedes aegypti

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 482-494, December 2024.
Different populations of Aedes aegypti, consisting of lab‐established and recently collected African lines display similar diurnal activity patterns. Despite this consistent diurnal activity, variations in activity and sleep levels are observed among the populations, where differences among lines were more pronounced in the lab‐adapted populations ...

Image_3_Light and Temperature Synchronizes Locomotor Activity in the Linden Bug, Pyrrhocoris apterus.TIF [PDF]

, 2020
Circadian clocks are synchronized with the external environment by light and temperature. The effect of these cues on behavior is well-characterized in Drosophila, however, little is known about synchronization in non-model insect species.

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

European 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 ...

Commodity risk assessment of Cornus alba and Cornus sanguinea plants from the UK

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘high risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by ...

Studies on assimilation, mobilization, and transport of lipids by the fat body and haemolymph of Pyrrhocoris apterus [PDF]

, 1969
The incorporation and release of lipid in vitro by the fat body of adult female Pyrrhocoris apterus, and the lipid content and composition of the haemolymph were examined in relation to the cyclic growth and diminution of the fat body and the probable ...

Body mass, temperature, and pathogen intensity differentially affect critical thermal maxima and their population‐level variation in a solitary bee

Ecology and Evolution, Volume 14, Issue 2, February 2024.
This study evaluates how body mass, local climate, and pathogen intensity influence heat tolerance and its population‐level variation among individuals of the solitary bee Xenoglossa pruinosa. We did not find evidence of microclimate predicting mean heat tolerance in X.
