Ultrastructural and microbial analyses of cellulose degradation in leaf-cutter ant colonies
(2017)
Leaf-cutter ants (Atta and Acromyrmex) use fresh leaves to cultivate a mutualistic fungus (Leucoagaricus gongylophorus) for food in underground gardens. A new ant queen propagates the cultivar by taking a small fragment ...
Soybean protease inhibitors increase Bacillus thuringiensis subs. israelensis toxicity against Hypothenemus hampei
(2020)
The coffee berry borer (Hypothenemus hampei Ferrari, CBB) is one of the most devastating pests on coffee plantations around the world. Although CBB is susceptible to the effect of δ–endotoxins ...
Evidence for Widespread Associations between Neotropical Hymenopteran Insects and Actinobacteria
(2017)
The evolutionary success of hymenopteran insects has been associated with complex physiological and behavioral defense mechanisms against pathogens and parasites. Among these strategies are symbiotic associations between ...
Papel de la bacteria endosimbionte Wolbachia en el control de enfermedades vectoriales: dengue, zika y chikunkunya
(2017)
Wolbachia es un género de bacterias perteneciente al orden Rickettsiales, que participa en diversas relaciones simbióticas con varios organismos, principalmente artrópodos y nematodos. Debido a su capacidad para inducir ...
Characterization of Batrachochytrium dendrobatidis Inhibiting Bacteria from Amphibian Populations in Costa Rica
(2017)
Global amphibian declines and extinction events are occurring at an unprecedented rate. While several factors are responsible for declines and extinction, the fungal pathogen Batrachochytrium dendrobatidis (Bd) has been ...
Streptomyces sp. M54: an actinobacteria associated with a neotropical social wasp with high potential for antibiotic production
(2021-01-17)
Abstract Streptomyces symbionts in insects have shown to be a valuable source of new antibiotics. Here,
we report the genome sequence and the potential for antibiotic production of ‘‘Streptomyces sp. M54’’, an Actinobacteria ...
Bacteria contribute to plant secondary compound degradation in a generalist herbivore system.
(2020)
Herbivores must overcome a variety of plant defenses, including coping
with plant secondary compounds (PSCs). To help detoxify these defensive chemicals,
several insect herbivores are known to harbor gut microbiota with ...
An Insect Herbivore Microbiome with High Plant Biomass-Degrading Capacity
(PLoS Genetics. September 2010. Volume 6, Issue 9. e1001129, 2010-09)
Herbivores can gain indirect access to recalcitrant carbon present in plant cell walls through symbiotic associations with lignocellulolytic microbes. A paradigmatic example is the leaf-cutter ant (Tribe: Attini), which ...
Habitat adaptation drives speciation of a Streptomyces species with distinct habitats and disparate geographic origins
(2022-01-11)
Microbial diversification is driven by geographic and ecological factors, but how the relative importance of these factors varies among species, geographic scales, and habitats remains unclear. Streptomyces, a genus of ...
Plant galls recorded from Guanacaste Conservation Area-Costa Rica as an integrated concept of a biological database
Registro de galhas em plantas da Área de Conservação Guanacaste, Costa Rica, como conceito integrado de um banco de dados biológico
(2021-07)
Galling insects are specialist herbivorous that have the ability of manipulating plant tissue to form complex biological structures called galls. Even though different organisms have the ability to induce galls in plants, ...
