The effect of trail length on task partitioning in three Acromyrmex species (Hymenoptera: Formicidae)
(2003-05-19)
By comparing the behavior of three Acromyrmex (Hymenoptera, Formicidae) species during foraging on artificial trails of different lengths, we observed the occurrence of task partitioning and its relation to the food distance ...
To exchange or not to exchange liquid food: is that the question for foraging leaf-cutting ant workers?
(2022-03-01)
Leaf-cutting ants forage fresh plants in the field to cultivate the symbiotic fungus in their nests. The trophallaxis rates in leaf-cutting ants may be related to liquid foraging behavior and exchanging liquid food with ...
Effects of entomopathogenic fungi on individuals as well as groups of workers and immatures of atta sexdens rubropilosa leaf-cutting ants
(2021-01-01)
In 2009, sulfluramid, the main ingredient in toxic baits for leaf-cutting ant control, was included in Annex B of the Stockholm Convention on Persistent Organic Pollutants. This resulted in interest in the use of ...

The metapleural glands of fungus-growing and non-fungus-growing ants: Ultrastructural study
(Brill Academic Publishers, 2014-01-01)
The metapleural glands are considered an autapomorphic structure to ants and probable have an antibiotic or antifungal function. The present study was aimed at investigating the ultrastructural morphology of the metapleural ...
Dynamics of physical trail construction and of trail usage in the leaf-cutting ant Atta laevigata
(2018-01-01)
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 ...
Leaf-cutting ants in commercial forest plantations of Brazil: biological aspects and control methods
(2020-04-02)
Forest plantations represent the fourth largest crop by planted area in Brazil. However, leaf-cutting ants can compromise their establishment and development. Atta and Acromyrmex (Hymenoptera: Formicidae) ant genera are ...
