Journal of Separation Science, Volume 49, Issue 7, July 2026.ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...

European 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.

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 725-735, July 2026.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.

Native insect species should be selected for classroom rearings
Insect Conservation and Diversity, Volume 19, Issue 1, Page 1-10, January 2026.Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach
Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

BMC Genomics, 2008 Background Nucleotide sequences and the gene arrangements of mitochondrial genomes are effective tools for resolving phylogenetic problems. Hemipteroid insects are known to possess highly reorganized mitochondrial genomes, but in the suborder Heteroptera

Temperature Tolerance and Thermal Environment of European Seed Bugs
Insects, 2020 Heteroptera, or true bugs populate many climate zones, coping with different environmental conditions. The aim of this study was the evaluation of their thermal limits and derived traits, as well as climatological parameters which might influence their ...

Comparative Analysis of Volatile Defensive Secretions of Three Species of Pyrrhocoridae (Insecta: Heteroptera) by Gas Chromatography-Mass Spectrometric Method. [PDF]
PLoS ONE, 2016 The true bugs (Hemiptera: Heteroptera) have evolved a system of well-developed scent glands that produce diverse and frequently strongly odorous compounds that act mainly as chemical protection against predators.

Journal of Applied Ecology, Volume 62, Issue 2, Page 360-370, February 2025.Our findings suggest that mowing in general has a negative impact on abundant arthropod groups in grassland, regardless of the method used. Tractor‐driven double‐blade bar mowers do not seem to be a truly insect‐friendly alternative to a conventional disc mower.
