Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

Physiological Entomology, Volume 50, Issue 3, Page 233-244, September 2025.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

Master of Puppets: How Microbiota Drive the Nematoda Ecology and Evolution?

Ecology and Evolution, Volume 15, Issue 8, August 2025.
The nematode microbiota can influence life‐history traits, thereby shaping the species' ecology and evolutionary trajectories. ABSTRACT In recent decades, the microbiota has emerged as a key driver of biological functions in metazoans, and nematodes are no exception.

Comparative screening of endosymbiotic bacteria associated with the asexual and sexual lineages of the termite Glyptotermes nakajimai

Communicative & Integrative Biology, 2019
Males provide opportunities both for sexual reproduction and for sex-based phenotypic differences within animal societies. In termites, the ubiquitous presence of both male and female workers and soldiers indicate that males play a critical role in ...

Foraging by predatory ants: A review

Insect Science, Volume 32, Issue 4, Page 1096-1118, August 2025.
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Loss of males from mixed-sex societies in termites

BMC Biology, 2018
Background Sexual reproduction is the norm in almost all animal species, and in many advanced animal societies, both males and females participate in social activities.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 5, Page 284-302, July 2025.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

Detection and characterization of Wolbachia infections in laboratory and natural populations of different species of tsetse flies (genus Glossina)

BMC Microbiology, 2012
Background Wolbachia is a genus of endosymbiotic α-Proteobacteria infecting a wide range of arthropods and filarial nematodes. Wolbachia is able to induce reproductive abnormalities such as cytoplasmic incompatibility (CI), thelytokous parthenogenesis ...

Newcomers and Old Friends: Long‐Distance and Bridgehead Introductions Both Contribute to the Recent Invasion of the Little Fire Ant in Southern Europe

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim Biological invasions result from the combination of (i) population dispersal opportunities and (ii) adaptations to the recipient environment. Identifying complex migration histories, made of long‐distance dispersal from the native range and secondary introductions, or genetic patterns indicative of adaptation is crucial to build coherent ...

Discrimination Against Non‐Nestmates Functions to Exclude Socially Parasitic Conspecifics in an Ant

Ethology, Volume 131, Issue 3, March 2025.
ABSTRACT Social animals utilise various communication methods to organise their societies. In social insects, nestmate discrimination plays a crucial role in regulating colony membership. Counter to this system, socially parasitic species employ diverse behavioural and chemical strategies to bypass their host's detection.

Dysdera parthenogenetica sp. nov. (Araneae, Dysderidae): A Unique Case of Parthenogenesis in Spiders

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
We studied the parthenogenetic lineages of the spider Dysdera hungarica (Araneae: Dysderidae). Based on our data, we consider them to constitute a separate taxon, Dysdera parthenogenetica sp. nov. Morphologically, the new species differs mainly by slightly reduced female copulatory organs.
