ALTERNATIVAS DE FORMICIDAS EM PÓ NO CONTROLE DA FORMIGA-VERMELHA-DE-MONTE, Acromyrmex heyeri [PDF]

, 2000
Com o objetivo de criar alternativas no controle químico da formiga-vermelha-de-monte, Acromyrmex heyeri (Forel, 1899) (Hymenoptera: Formicidae, Attini) foram instalados quatro ensaios com formicidas em pó, em Santa Maria, estado do Rio Grande do Sul ...

Chromosome Mapping of Ribosomal DNA Clusters in Four Leaf-cutting Ant Species of the Genus Acromyrmex, with Description of a Triploid Individual in A. laticeps

Sociobiology
The increase of cytogenetic data in the leaf-cutting genus Acromyrmex has shown interesting contributions to the evolutionary and taxonomic approaches, including the creation of a new genus and the description of chromosomal patterns allowing ...

Sperm mixing in the polyandrous leaf-cutting ant Acromyrmex echinatior [PDF]

, 2014
The insemination of queens by sperm from multiple males (polyandry) has evolved in a number of eusocial insect lineages despite the likely costs of the behavior.

How to coexist with fire ants: The roles of behaviour and cuticular compounds [PDF]

, 2013
tBecause territoriality is energetically costly, territorial animals frequently respond less aggressively toneighbours than to strangers, a reaction known as the “dear enemy phenomenon” (DEP).

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Chromosomal Diversity as a Predictor of Lineage Diversification in Ants Across Phylogenetic and Geographic Gradients

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Extensive Field Observations Throw Light on the Evolution of Mimicry in Camponotus lateralis (Hymenoptera: Formicidae)

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Camponotus lateralis (C, D) mimics regional color morphs of Crematogaster (A, B). Field trips brought insights into ecology, trail sharing, sexual reproduction, colony foundation, nest defense, and predation pressure of this mimetic ant. We found that the mimicry is Batesian and suggest several preadaptations for its evolution.

Beetle Pollination in the Holoparasitic Lophophytum pyramidale (Balanophoraceae): A New Case of Brood‐Pollination Mutualism?

Journal of Applied Entomology, Volume 149, Issue 10, Page 1542-1554, December 2025.
ABSTRACT Beetle pollination is considered an ancestral trait in angiosperms, retained in a few specialised families engaging in longstanding interactions with ancient groups of beetles. While beetles represent some of the earliest angiosperm pollinators, there is also increasing evidence that some beetle‐pollinated plants represent a derived condition.
