Atta ant.

The ants cut pieces of leaves, using their jaws and transport the fragments to the nest below the ground which consists of 1,000 compartments and accommodate millions of single ants. The ants belonging to the genus of Atta are distinguished by ants of different sizes based on their responsibilities like the soldiers, worker ants.The group of ants that are LeafCutters belong to the tribe attini and their genera is Atta and acromyrmex These ants have been around for the better part of 50 million years. Interestingly, these ants are consume the largest amount of primary producers in the tropical rainforest areas which is not surprising considering their biomass is four ...In the fungus-growing ant genus Atta, foundress queens nourish their brood and incipient fungus gardens with nutrients derived from trophic eggs. We discovered a third kind of egg laid by Atta foundresses in addition to reproductive and trophic eggs. We use fluorescent microscopy to show that this third type of eggs represents reproductive eggs that are unviable and fail to develop. Unviable ...For example, Escovopsis has been isolated from waste samples in several species of Atta and Acromyrmex [6,25,34], and contact with waste materials increases mortality of ant workers [6,35]. Accordingly, LCA workers avoid contact with waste [ 36 , 37 ] and show a clear division of labour between waste workers and foragers [ 9 , 18 , 19 ].

Life Cycle of an Ant Colony An ant colony begins in the founding stage. After mating, the queen(s) starts a new nest and raises her first worker offspring. This is the only time in a queen's life that she does work in addition to laying eggs. During the growth stage, the colony grows larger by producing more workers. The workers now perform all the colony's jobs except layingOur study demonstrates that species of Atta ants are not randomly dispersed in Brazil and are strongly associated with complex and diverse Brazilian landscapes. We remark that further studies on ...

Sampling of colonies. We sampled colonies of leaf-cutter ants (Atta sexdens rubropilosa) inside and outside of São Paulo.Our samples included four urban colonies near the University of São Paulo and five rural colonies distributed along a north-westerly transect (Fig. 1).We only collected ants that were walking along trails, carrying leaves or pieces of leaves.In this study, a leaf-cutting ant Atta sexdens DNA fragment containing 1623 base pairs was amplified and cloned into a vector to express the protein (AsChtII-C4B1) in Pichia pastoris. AsChtII-C4B1, which contains one catalytic domain and one carbohydrate-binding module (CBM), was secreted to the extracellular medium and purified by ammonium ...

Ruthless and violent, but also cunning, Hopper thinks nothing of killing ants, whom he considers lower than dirt, and his manner of speaking to Princess Atta is reminiscent of an abusive boyfriend mocking his terrified girlfriend. He …For example, Escovopsis has been isolated from waste samples in several species of Atta and Acromyrmex [6,25,34], and contact with waste materials increases mortality of ant workers [6,35].

There are relatively few data on the life span and degree of survival of ants [].Studies related to oviposition rates, and the development of larvae, pupae, and adult leaf-cutting ants are also scarce in the literature [].However, studies related to egg laying, life cycle, and longevity are pertinent, and support basic studies in behavior and population ecology as well as ...In the leaf-cutting ant Atta colombica, queens receive ejaculates from multiple males during one single mating event early in their lives. A queen's fertility and fitness therefore depend on maximizing the number of sperm cells she can store and maintain inside her spermatheca. Previous studies implied significant physiological mating costs, either originating from energetic investments ...We found that predatory army ants (Eciton burchellii) as well as non-predatory leaf-cutting ants (Atta cephalotes and Acromyrmex volcanus) avoided adult N. clavipes silk, suggesting that an additional …The individual ant chews off a portion of leaf that it can carry, often more than three times larger than itself. It hoists the leaf above its head using its jaws. The leaf tends to cast shade onto the ant carrying it, like a tiny umbrella, rendering the nickname "parasol ants". It races back to the colony to deliver its offering.Leafcutter ant is the general name for any of 47 species of leaf-chewing ants of the two genera Atta and Acromyrmex.These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico and parts of the southern United States.Leafcutter ants "cut and process fresh vegetation (leaves, flowers, and grasses) to serve as nutrition for their fungal cultivars".New World army ants (Ecitoninae) are specialist social predators of other ants, and the army ant Nomamyrmex esenbeckii, a primarily subterranean species, is known to prey upon young Atta colonies.
