(Zapolskikh et al., 1981), Atta laevigata (Giannotti and Caetano, 1985), and Atta cephalotes (Valência-Giraldo et al., 2021). Ants are among the most abundant and important insects in various environments.The mechanisms affecting forest regeneration in human‐modified landscapes are attracting increasing attention as tropical forests have been recognized as key habitats for biodiversity conservation, provision of ecosystem services, and human well‐being. Here we investigate the effect of the leaf‐cutting ants (LCA) Atta opaciceps on regenerating plant assemblages in Caatinga dry forest ...description In leafcutter ant Nests of the Atta genus are characterized by ants of different sizes corresponding to castes of workers, soldiers, reproductives, and “guards.” Deep within the nest, the ants physically …

Leaf-cutting Ant (Atta cephalotes) The highly social leaf-cutting ant is named for its habit of cutting and carrying leaves back to its underground nest. The ants do not eat the leaves. Instead, the leaf fragments are used as compost to grow fungus gardens that feed the ants.The leaf‐cutting ant Atta bisphaerica Forel (Hymenoptera: Formicidae, Attini) forages leaves from monocotyledons in natural environments and is a serious pest of pastures and sugarcane ...Leafcutter ants, a non-generic name, are any of 41 species of leaf-chewing ants belonging to the two genera Atta and Acromyrmex. These species of tropical, fungus-growing ants are all endemic to South and Central America and parts of the southern United States. The Acromyrmex and Atta ants have much in common anatomically; however, the two can …Graph comparing the difference in Pseudonocardia coverage (mean ± SE) on Acromyrmex echinatior workers carrying the Pseudonocardia ectosymbiont from different leaf-cutter ant species (cross-fostered) and when these Acromyrmex species are reared by their conspecific nestmates (native colony). The bar within the dashed lines represents A. echinatior ants raised only by their own colony, and A ...

The colonies we sell are primarily colonies with queens, instead of just worker ants. What's different is that these colonies are able to grow, and live for years instead of months. Most of our ant set ups are actually pre-carved chambers, and so they have no digging, and extra visibility, since you can see the inner workings of the entire colony.Among the attines, ants in the two genera of leaf-cutting ants (Acromyrmex and Atta) exhibit the most complex fungicultural systems.Fungiculture among Atta supports colony populations in the millions of workers and explains why leafcutters are the dominant herbivore in the Neotropics ().Colonies of Atta spp. can survive for extended periods, often living for 8-10 years or more after initial ...Atta is a genus of New World ants of the subfamily Myrmicinae. It contains at least 17 known species. Atta leaf-cutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs. The three main castes within a nest are the queen, worker, and soldier. Only the queens and males have … See more ….

Before Hopper can execute Flik, he is stopped by Atta. Inspired by Flik's speech, the entire colony of ants stands up against the grasshoppers. As the colony charges towards Hopper's gang, they abandon their leader and flee, leaving Hopper to be seized by the ants and trapped in a circus cannon, right at the time when a thunderstorm starts.Before Hopper can execute Flik, he is stopped by Atta.

Dec 1, 2020 · Bulkholderia species have also been found in fungus-growing ant nests, and one strain isolated from an Atta sexdens rubropilosa colony inhibited the growth of E. weberi and other fungal pathogens, but not L. gongylophorus [43]. These reports hint at the much more complex interplay of different species in the nests of fungus growing ants, beyond ... The life cycle of leafcutter ants. Leafcutting ants comprise 24 known species of Acromyrmex (Table 17-1) and 15 of Atta (Table 17-2). Because the Atta workers are so large and spectacular in their behavior, many entomologists have set out to study their life cycle and biology.To assure the correct stereochemical assignment, (S)-1 was converted in the known ketone (S)-5: the main alarm pheromone of the ant Atta texana that is 400 times more active than its (R)-enantiomers. Leaf-cutter ant species (Hymenoptera: Atta) differ in the types of cues used to differentiate between self and others

Foraging in leaf-cutting ants is generally organized along well-defined recruitment trails supporting a bi-directional flow of outbound and nestbound individuals. This study attempts to reveal the priority rules governing the organization of traffic on these trails. Ants were forced to move on a narrow trail, allowing the passage of only two individuals at a time. In this condition, a ...
