Leafcutter ants are fascinating creatures that play a vital role in their ecosystems. These tiny architects are known for their unique ability to cultivate fungi, which they use as their primary food source. This blog post will explore the intricate relationship between leafcutter ants and fungi, highlighting how these interactions shape their environment and influence their survival. Leafcutter ants belong to the tribe Attini, which includes over 200 species. They are primar

In the world of nature, tiny creatures often hold big secrets. Among these, insects and microbes share a fascinating relationship that plays a crucial role in our ecosystem. These relationships are not just interesting; they are vital for the survival of many species, including humans. Insects, which make up a significant portion of the animal kingdom, interact with various microbes in ways that can be both beneficial and harmful. Understanding these interactions can help us

In the intricate web of life, few relationships are as fascinating as those between insects and fungi. These partnerships, known as symbioses, are not just a matter of coexistence; they are dynamic interactions that can shape ecosystems. Recent research has shed light on how these relationships work, revealing their complexity and importance. In this blog post, we will explore the latest findings in insect-fungi symbioses, highlighting their roles in nature, their benefits to

CLIQUE AQUI E LEIA O ARTIGO COMPLETO Abstract Social insects can live in densely populated colonies where mortality risks are increased by inter-individual transmission of pathogens. Thus, diverse strategies are employed against such infection risks, including the display of sophisticated behavioural traits. Considering that the waste of the leaf-cutting ant contains pathogens, worker ants that tend the fungus garden – here called fungus garden workers – should exhibit avoida

Leaf-cutting ants live in big societies that have a very developed structure and elaborate division of labor. because different castes are subject to different levels of parasitism, it is expected that workers adjust their innate immune system to minimize fitness loss. We tested for this possibility by measuring encapsulation rate in different groups of Atta sexdens rubropilosa workers: workers of the fungus garden (GAR), foragers (FOR), leaf transporters (LTR), waste transpo

Danival José de Souza 1, Alain Lenoir, Maria Catarina Megumi Kasuya, Myriam Marques Ramos Ribeiro, Séverine Devers, Joel da Cruz Couceiro, Terezinha Maria Castro Della Lucia Abstract Associations with symbiotic organisms can serve as a strategy for social insects to resist pathogens. Antibiotics produced by attine ectosymbionts (Actinobacteria) suppress the growth of Escovopsis spp., the specialized parasite of attine fungus gardens. Our objective was to evaluate whether the

Many of them live in association with large multicellular organisms, developing symbiotic relations with the host and some have even evolved to form obligate endosymbiosis [1]. All Carpenter ants (genus Camponotus) studied hitherto harbour primary endosymbiotic bacteria of the Blochmannia genus. The role of these bacteria in ant nutrition has been demonstrated [2] but the om
