Thelytokous Parthenogenesis in the Ant Strumigenys hexamera (Hymenoptera: Formicidae)

Annals of the Entomological Society of America, 2013
Abstract Strumigenys hexamera (Brown) is a terrestrial ant nesting exclusively in the soil and specialized in predation on diplurans and small-sized myriapods (symphyllans and centipedes). Its colony is monogynous and previous dissections of the queens had suggested that they were uninseminated, thus they could reproduce thelytokously ...

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.

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

ITS-2 sequences-based identification of Trichogramma species in South America

Brazilian Journal of Biology
ITS2 (Internal transcribed spacer 2) sequences have been used in systematic studies and proved to be useful in providing a reliable identification of Trichogramma species. DNAr sequences ranged in size from 379 to 632 bp. In eleven T.

Parthenogenetic vs. sexual reproduction in oribatid mite communities

Ecology and Evolution, 2019
The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and exposure to diseases and predators ...

Reproductive Biology of the Cape Honeybee: A Critique of Beekman et al: A critique of "Asexually Produced Cape Honeybee Queens (Apis mellifera capensis) Reproduce Sexually,” authors: Madeleine Beekman, Michael H. Allsopp, Julianne Lim, Frances Goudie, and Benjamin P. Oldroyd. Journal of Heredity. 2011:102(5):562-566 [PDF]

, 2017
Laying workers of the Cape honeybee parthenogenetically produce female offspring, whereas queens typically produce males. Beekman et al. confirm this observation, which has repeatedly been reported over the last 100 years including the notion that ...

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 ...

Parasitic Cape honeybee workers, Apis mellifera capensis, evade policing [PDF]

, 2002
Relocation of the Cape honeybee, Apis mellifera capensis, by bee-keepers from southern to northern South Africa in 1990 has caused widespread death of managed African honeybee, A. m. scutellata, colonies.

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
