Microbial Communities in Different Tissues of Atta sexdens rubropilosa Leaf-cutting Ants [PDF]

Current Microbiology, 2017
Bacterial endosymbionts are common in all insects, and symbiosis has played an integral role in ant evolution. Atta sexdens rubropilosa leaf-cutting ants cultivate their symbiotic fungus using fresh leaves. They need to defend themselves and their brood against diseases, but they also need to defend their obligate fungus gardens, their primary food ...

Mind the gap! Integrating taxonomic approaches to assess ant diversity at the southern extreme of the Atlantic Forest [PDF]

, 2017
Understanding patterns of species diversity rely on accurate taxonomy which can only be achieved by long-term natural history research and the use of complementary information to establish species boundaries among cryptic taxa.

LEVANTAMENTO DE Atta sexdens rubropilosa e Atta laevigata EM FLORESTAS CULTIVADAS DE EUCALIPTOS

, 2022
Introdução: O eucalipto é a principal espécie florestal cultivada em solos Brasileiros com aproximadamente 7,7 milhões de hectares. As formigas cortadeiras do gênero Atta são consideradas as principais pragas florestais do continente americano. Essa praga corta as folhas do eucalipto para o cultivo simbionte de um fungo. Elas se alimentam desses fungos
