New fossil ephialtitids elucidating the origin and transformation of the propodeal-metasomal articulation in Apocrita (Hymenoptera) [PDF]

BMC Evolutionary Biology, 2015
Apocrita has a special structure that its first abdominal segment has been incorporated into the thorax as the propodeum. The remaining abdomen, metasoma, is connected to this hybrid region via a narrow propodeal-metasomal articulation forming a "wasp waist", which serves an important function of providing maneuverability, flexibility and posture for ...

Phylogenetic relationships among superfamilies of Hymenoptera [PDF]

, 2011
The first comprehensive analysis of higher-level phylogeny of the order Hymenoptera is presented. The analysis includes representatives of all extant superfamilies, scored for 392 morphological characters, and sequence data for four loci (18S, 28S, COI ...

The influence of cutting height on arthropods in farm grassland

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1124-1139, September 2026.
Mowing at a cutting height of 13 cm slightly reduced the immediate negative impact of mowing compared to mowing at a height of 7 cm. Medium‐term effects overrode this benefit: the number of vegetation‐dwelling arthropods remained strongly reduced two and four weeks after mowing, regardless of the cutting height.

Hidden Microbiota Inhabiting in Pollen Reserves of Honey Bee (Apis mellifera) From Amazonas Region Revealed by DNA Metabarcoding

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
DNA metabarcoding of honey bee pollen reserves from Amazonas region reveals that microbial communities are strongly shaped by their ecosystem. Despite high taxonomic turnover across different habitats, these microbiomes maintain stable, essential functions for pollinator health, though they remain highly vulnerable to habitat homogenization.

Identification and characterization of globin gene from Bombus terrestris (Hymenoptera: Apocrita: Apidae)

Biologia, 2023
Hemoglobins are mainly functional in the transport and storage of O2, and are present in aerobic, lung respiratory metazoans. Based on recent studies, it has been determined that globin-like proteins are also found in invertebrate groups which have tracheal respiratory systems.

Function of the Dufour’s gland in solitary and social Hymenoptera

Journal of Hymenoptera Research, 2013
The poison gland and Dufour’s gland are the two glands associated with the sting apparatus in female Apocrita (Hymenoptera). While the poison gland usually functions as an integral part of the venom delivery system, the Dufour’s gland has ...

Accelerated evolution of mitochondrial but not nuclear genomes of Hymenoptera: new evidence from crabronid wasps. [PDF]

PLoS ONE, 2012
Mitochondrial genes in animals are especially useful as molecular markers for the reconstruction of phylogenies among closely related taxa, due to the generally high substitution rates.
