Dynamics of physical trail construction and of trail usage in the leaf-cutting ant Atta laevigata [PDF]

Ethology Ecology & Evolution, 2018
Leaf cutting ants of the genus Atta build long lasting physical trails to exploit the vegetation around their nest. In this paper we investigated the dynamics of physical trail construction and usage in the leaf-cutting ant Atta laevigata.

Controle de Atta laevigata (Hymenoptera: Formicidae) com a isca Landrin-F, em área anteriormente coberta com Eucalyptus Control of Atta laevigata (Hymenoptera: Formicidae), with Landrin-F bait, in areas previously covered with Eucalyptus

Ciência Rural, 1999
Embora muitos produtos tenham sido testados como princípio ativo de iscas formicidas, o mercado predominantemente utilizava produtos à base de dodecacloro. Com a proibição deste último composto, surgiram as iscas à base de sulfluramida ou de clorpirifós,

Topical Toxicity of Esenbeckia pumila Extracts on Leaf-Cutting Ants Atta laevigata and Acromyrmex balzani

Journal of Agricultural Science, 2017
The aim of this study was to evaluate the topical toxicity of the Esenbeckia pumila plant extracts on workers of the Atta laevigata and Acromyrmex balzani. Five leaf fractions E.

Distinct and enhanced hygienic responses of a leaf-cutting ant toward repeated fungi exposures. [PDF]

Ecol Evol, 2022
The leaf‐cutting ant Atta sexdens discriminates between different antagonistic fungi and apply distinct responses to remove them from the fungus garden. Also, successive exposures to the same antagonist increase sanitization in the fungus garden.

DISTRIBUIÇÃO DE SUBSTRATOS NAS COLÔNIAS DE Atta laevigata (F. Smith, 1858) (HYMENOPTERA: FORMICIDAE)

Scientia Agricola, 1999
Estudou-se a distribuição de substratos em duas colônias adultas (L-1 e L-2) da saúva Atta laevigata (F. Smith, 1858), com áreas de terra solta de 26,10 e 31,30 m2.

Ant Diversity and Stratification in an Amazonian Rainforest. [PDF]

Ecol Evol
We examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

Shifts in Chromosome Evolution Rates Shape the Karyotype Patterns of Leafcutting Ants. [PDF]

Ecol Evol
Modern phylogenetic methods were used to explore how chromosome number and other karyotypic traits vary across species. The focus was on testing whether karyotypic traits follow a Brownian motion model (indicating neutral changes) or are influenced by phylogenetic constraints.This research elucidates the mechanisms underlying chromosomal evolution and ...

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants. [PDF]

Ecol Evol
We use data from 73 Neotropical ant species to examine the strength of associations between nine morphological traits and trophic position. No individual morphological trait explained variation in the trophic position of arboreal species, whereas three traits individually correlated with the trophic position of ground species, but only weakly so ...

Large deformation diffeomorphic mapping of 3D shape variation reveals two distinct mandible and head capsule morphs in Atta vollenweideri leaf-cutter worker ants. [PDF]

Ecol Evol
Atta vollenweideri leaf‐cutter ant workers vary continously in size across more than two orders of magnitude in body mass. We investigated whether size‐variation correlates with shape variation by analysing the 3D morphology of mandibles and head capsules.

New behavior report by Canthon virens (Mannerheim, 1829) (Coleoptera: Scarabaeidae: Scarabaeinae) in Southeastern Brazil

Entomological Communications, 2022
Canthon virens (Mannerheim, 1829) (Coleoptera: Scarabaeidae: Scarabaeinae) prey on leaf-cutting ants, using their body for provisioning larvae, as part of the reproductive behavior. Here, we report an observation of a new behavior of C.
