Seasonal activity-profiles of enzymes involved in cryoprotectant biosynthesis in Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2008
The activities of three enzymes involved in polyol biosynthesis (aldose reductase, AR; ketose reductase, KR; and polyol dehydrogenase, PDH) were studied in adult females of the linden bug, Pyrrhocoris apterus, collected from the field during 2005/2006 ...

Diversity of Resilin Incidence in the Insect Leg

open access: yesJournal of Morphology, Volume 287, Issue 6, June 2026.
Resilin incidences in the insect cuticle are commonly detected by fluorescence microscopy using the property of Resilin protein matrices to emit blue light after excitation with UV light. This indirect method produces significant background signal.

Thermal acclimatization does not affect the resting activity of type T1 trichobothrium in the fi rebug (Pyrrhocoris apterus; Heteroptera)

open access: yesActa Biologica Slovenica, 2007
Firebugs (Pyrrhocoris apterus) pass through the winter in adult state. They undergo a series of physiological changes in order to increase their capacity to survive at low ambient temperatures. Nevertheless, even during winter their body temperature can

Role of Methoprene-tolerant (Met) in adult morphogenesis and in adult ecdysis of Blattella germanica. [PDF]

open access: yesPLoS ONE, 2014
Juvenile Hormone (JH) represses metamorphosis of young instars in insects. One of the main players in hormonal signalling is Methoprene-tolerant (Met), which plays the role of JH receptor.

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

open access: yesGenes, 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 ...

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

Genome of Leptomonas pyrrhocoris: a high-quality reference for monoxenous trypanosomatids and new insights into evolution of Leishmania [PDF]

open access: yes, 2016
Many high-quality genomes are available for dixenous (two hosts) trypanosomatid species of the genera Trypanosoma, Leishmania, and Phytomonas, but only fragmentary information is available for monoxenous (single-host) trypanosomatids. In trypanosomatids,

Methoprene modifies adipokinetic hormone characteristics in the firebug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2010
In the present study the hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by topical application of the juvenoid methoprene on 9-day-old adult males of the firebug Pyrrhocoris apterus.

Role of Litsea cubeba Essential Oil in Agricultural Products Safety: Antioxidant and Antimicrobial Applications

open access: yesPlants, 2022
The essential oil from Litsea cubeba (LCEO) has good antioxidant, antimicrobial, anti-insect properties, which gives it the potential for use as a natural additive to food resources and food products in order to prevent spoilage and extend shelf life. In

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew Plant Protection, Volume 3, Issue 1, March 2026.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.
