Shared Escovopsis parasites between leaf-cutting and non-leaf-cutting ants in the higher attine fungus-growing ant symbiosis [PDF]
Royal Society Open Science, 2015 Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens.

Fungal-Fungal Interactions in Leaf-Cutting Ant Agriculture
Psyche: A Journal of Entomology, 2011 Many organisms participate in symbiotic relationships with other organisms, yet studies of symbioses typically have focused on the reciprocal costs and benefits within a particular host-symbiont pair.

Adaptive social immunity in leaf-cutting ants [PDF]
Biology Letters, 2009 Social insects have evolved a suite of sophisticated defences against parasites. In addition to the individual physiological immune response, social insects also express ‘social immunity’ consisting of group-level defences and behaviours that include allogrooming.

Susceptibility of Atta sexdens worker ants treated with the immunosuppressant Sandimmun Neoral to Metarhizium anisopliae [PDF]
Pesquisa Agropecuária Brasileira, 2017 : The objective of this work was to evaluate if the immunosuppressant Sandimmun Neoral enhances the activity of Metarhizium anisopliae against the leaf-cutting ant Atta sexdens.

Leaf endophyte load influences fungal garden development in leaf-cutting ants
BMC Ecology, 2012 Background Previous work has shown that leaf-cutting ants prefer to cut leaf material with relatively low fungal endophyte content. This preference suggests that fungal endophytes exact a cost on the ants or on the development of their colonies.

Genetic polyethism in leaf-cutting ants [PDF]
Behavioral Ecology, 2010 Females mating with multiple males (polyandry) is taxonomically widespread but is hard to explain in many animals in which it has no obvious direct benefits. In some, of which social insects are the best example, it is suggested that females benefit from the increased genetic diversity of their offspring.

Ecosphere, 2013 Endophytic fungi live symbiotically in the tissues of plants. Although a large amount of evidence suggests a mutualistic role for vertically transmitted endophytic fungi in agronomic grasses, the role of horizontally transmitted endophytic fungi as ...

Absence of the Parasite Escovopsis in Fungus Garden Pellets Carried by Gynes of Atta sexdens
Sociobiology, 2015 Before preparing for the mating flight gynes of leaf-cutting ants (Hymenoptera: Formicidae: Attini) harvest and store in an infrabuccal pocket a small fragment of their fungus gardens. This pellet is the start culture of the mutualistic fungus when mated

Agriculture, 2023 Leaf-cutting ants are important pests of agricultural and forest crops. Currently, few insecticides are registered for the control of these insects. Natural bioactive molecules can serve as models for the synthesis of new insecticidal compounds. Such ant
