A metabolic pathway assembled by enzyme selection may support herbivory of leaf-cutter ants on plant starch
(2013-05-01)
Mutualistic associations shape the evolution in different organism groups. The association between the leaf-cutter ant Atta sexdens and the basidiomycete fungus Leucoagaricus gongylophorus has enabled them to degrade starch ...
Do Workers from Subspecies Acromyrmex subterraneus Prepare Leaves and Toxic Baits in Similar Ways for Their Fungus Garden?
(Entomological Soc Brasil, 2020-02-01)
Toxic baits are the most efficient method to control leaf-cutter ants in eucalyptus forests for paper and cellulose production. For the proper use of these baits, insecticide compounds must reach workers and contaminate ...
Acromyrmex charruanus: a new inquiline social parasite species of leaf-cutting ants
(Springer, 2015-08-01)
Social parasites exploit the colony resources of social species to secure their own survival and reproduction. Social parasites are frequently studied as models for conflict and cooperation as well as for speciation. The ...
Virola sebifera Aubl. (Myristicaceae) leaf chemical composition and implications on leaf-cutter ant foraging choice
(2018-06-01)
Leaf-cutter ant plant material choice is essential for colony maintenance and growth. Plant material is used as a substrate for cultivating symbiotic fungus, and the ants’ preference for particular leaves, tends to be ...
Herbivory by leaf-cutter ants changes the glandular trichomes density and the volatile components in an aromatic plant model
(2017-11-01)
Herbivory can induce several structural and functional alterations in the plant secretory system. Glandular trichomes are the main sites of production of volatile organic compounds (VOCs) with several chemical properties ...
Leaf-cutter ant fungus gardens are biphasic mixed microbial bioreactors that convert plant biomass to polyols with biotechnological applications
(Amer Soc Microbiology, 2015-07-01)
Leaf-cutter ants use plant matter to culture the obligate mutualistic basidiomycete Leucoagaricus gongylophorus. This fungus mediates ant nutrition on plant resources. Furthermore, other microbes living in the fungus garden ...
Fat-Soluble Substance Flow During Symbiotic Fungus Cultivation by Leaf-Cutter Ants
(Entomological Soc Brasil, 2019-11-07)
Leaf-cutter ants perform a series of specialized behaviors in preparing plant substrates for their symbiotic fungus. This process may be related to contamination of workers by substances such as insecticides, leading us ...
