Formicidal Potential of Thymol Derivatives: Adverse Effects on the Survival and Behavior of Acromyrmex balzani

Agriculture, 2023
Leaf-cutting ants are important pests of agricultural and forest crops. Currently, few insecticides are registered for the control of these insects. Natural bioactive molecules can serve as models for the synthesis of new insecticidal compounds. Such ant

Action mode of fipronil and sulfluramid in baits on Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae) in laboratory conditions

BioAssay, 2023
The leaf-cutting ants (LCAs) of the genus Atta Fabricius, 1804 and Acromyrmex Mayr, 1865 (Hymenoptera: Formicidae) are major pests in forest plantations, agriculture and livestock.

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.

PATHOGENICITY OF ISOLATES OF ENTOMOPATHOGENIC FUNGI TO WORKERS OF Acromyrmex heyeri (Forel, 1899) (HYMENOPTERA: FORMICIDAE)

FLORESTA, 2023
Leaf-cutting ants stand out among the main pests of agricultural and forestry crops. Chemical control is the most used method to control these insect pests, requiring the development of techniques that are less harmful to the environment.

Recognition and Aggression of conspecific and heterospecific worker in Acromyrmex subterraneus subterraneus (Forel) (Hymenoptera: Formicidae)

Sociobiology, 2015
Aggressive behavior is important for social insects because it makes possible for the colony to defend itself and the offspring from the action of invasive species.

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.

Parasitismo e respostas comportamentais de Acromyrmex coronatus (Fabricius, 1804) e Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae) a Myrmosicarius catharinensis Borgmeier, 1928 (Diptera: Phoridae) em Londrina, PR

Semina: Ciências Agrárias, 2021
Formigas-cortadeiras do gênero Acromyrmex causam sérios prejuízos em áreas florestais cultivadas. Algumas moscas pertencentes à família Phoridae são conhecidas por parasitá-las e o resultado dessa interação pode fornecer bases promissoras para o manejo ...

Phylogenomic analysis and metabolic role reconstruction of mutualistic Rhizobiales hindgut symbionts of Acromyrmex leaf-cutting ants.

FEMS Microbiology Ecology, 2022
Rhizobiales are well-known plant-root nitrogen-fixing symbionts, but the functions of insect-associated Rhizobiales are poorly understood. We obtained genomes of three strains associated with Acromyrmex leaf-cutting ants and show that, in spite of being ...
