Observation of leaf-cutting ants foraging on wild mushrooms
(Birkhauser Verlag Ag, 2012-05-25)
This study reports on the observation of an unusual behavior in leaf-cutting ants: foraging on wild mushrooms. A colony of Acromyrmex lundi in Buenos Aires (Argentina) was observed intensively harvesting basidiomes (mushroom ...
Novel organic repellent for leaf-cutting ants: tea tree oil and its potential use as a management tool
(Taylor & Francis Ltd, 2019-09)
Leaf-cutting ants are insects of great economic importance which cause economic losses in numerous crops. Compounds that modulate behaviour, and among these natural repellents, show promise in integrated pest management ...
Hongos simbiontes de hormigas cortadoras de hojas del género Acromyrmex en bosques secos del centro de ArgentinaFungal symbionts of leaf-cutting ants of the genus acromyrmex in dry forest of central argentina
(Instituto de Botánica Darwinion, 2021-03)
Fungi associated with leaf-cutter ants (LCAs) play a fundamental role in Neotropical ecosystems. The association with fungi allows LCAs to be the dominant herbivores and in this way influence ecological processes. In order ...
The Effect of nest Size and Species Identity on Plant Selection in Acromyrmex Leaf-Cutting Ants
(Universidade Estadual de Feira de Santana, 2018-09)
Leaf-cutting ants are key organisms because their role as primary consumers and potential agricultural pests. However, their foraging ecology was mostly studied as response of extrinsic factors such as climate and plant ...
Potential impact of the leaf‐cutting ant Acromyrmex lobicornis on conifer plantations in northern Patagonia, Argentina
(Wiley, 2011-05)
The economic losses associated with crop damage by invasive pests can be minimized by recognizing their potential impact before they spread into new areas or crops. We experimentally evaluated the preferences of the ...
Isolation of the symbiotic fungus of Acromyrmex pubescens and phylogeny of Leucoagaricus gongylophorus from leaf-cutting ants
(Elsevier B.V., 2017-05)
Leaf-cutting ants live in an obligate symbiosis with a Leucoagaricus species, a basidiomycete that serves as a food source to the larvae and queen. The aim of this work was to isolate, identify and complete the phylogenetic ...
Collective response of leaf-cutting ants to the effects of wind on foraging activity
(University of Chicago Press, 2016-11)
One advantage of sociality is to mitigate environmental restrictions through collective behavior. Here we document a colony-level response of leaf-cutting ants to wind, an environmental factor that impedes foraging. Given ...
Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants
(Academia Brasileira de Ciencias, 2019-08)
Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to ...
Wind disrupts trail pheromone communication in the leaf-cutting ant Acromyrmex lobicornis
(Elsevier, 2022-10)
Although wind is a ubiquitous component of ecological systems and might affect pheromone communication, its effects have not been studied in depth. To test whether wind impacts trail pheromone behaviour, we studied the ...
Refuse attracts? Effect of refuse dumps of leaf-cutting ants on floral traits
(Wiley Blackwell Publishing, Inc, 2019-02-13)
The nutrient-rich organic waste generated by ants may affect plant reproductive success directly by enhancing fruit production but also indirectly, by affecting floral traits related with pollinator attraction. Understanding ...
