Novel Worker-Like Behavior Observed in Gynes of the Social Parasite <i>Tetramorium microgyna</i>. [PDF]
Ecol EvolOur article reports, to our knowledge, the first observations of inquiline gynes performing worker tasks for their host colony. We dissected these gynes to establish that they were all unmated. We hypothesize that nest excavation by social parasites represents an artifact of a non‐parasitic past.

Spiroplasma Display an Intricate Continuum of Infection Heterogeneity and Persistence in Myrmica Ants. [PDF]
Mol EcolABSTRACT Many bacterial taxa evolved facultative symbiotic associations with insects and spread through host populations by horizontal and maternal transmission. Co‐infection at the individual host level may facilitate or constrain the spread of facultative symbionts.

Isoenzyme variation in the leaf-cutting ants Acromyrmex heyeri and Acromyrmex striatus (Hymenoptera, formicidae) [PDF]
Genetics and Molecular Biology, 2002 This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul.

The effect of homeopathic preparations on the activity level of Acromyrmex leaf-cutting ants=Atividade de formigas cortadeiras Acromyrmex spp. submetidas a preparações homeopáticas [PDF]
Acta Scientiarum. Agronomy, 2012 The effect of homeopathic preparations on the activities of the leaf-cutting ants Acromyrmex spp. was studied. A field experiment involving ant nests in six experimental areas was performed using a randomised complete block design.

mBio, 2021 Many fungus-growing ants engage in a defensive symbiosis with antibiotic-producing ectosymbiotic bacteria in the genus Pseudonocardia, which help protect the ants’ fungal mutualist from a specialized mycoparasite, Escovopsis.

Differences in forage-acquisition and fungal enzyme activity contribute to niche segregation in Panamanian leaf-cutting ants. [PDF]
PLoS ONE, 2014 The genera Atta and Acromyrmex are often grouped as leaf-cutting ants for pest management assessments and ecological surveys, although their mature colony sizes and foraging niches may differ substantially.

Cytogenetic and molecular analyses reveal a divergence between Acromyrmex striatus (Roger, 1863) and other congeneric species: taxonomic implications. [PDF]
PLoS ONE, 2013 The leafcutter ants, which consist of Acromyrmex and Atta genera, are restricted to the New World and they are considered the main herbivores in the neotropics.
