Research related to the comparative biology of phylogenetically close ant species has received little attention, although it is the basis for understanding the systematics of some sibling groups. The objective was to study ... -
Exposure to thiamethoxam during the larval phase affects synapsin levels in the brain of the honey bee
Tavares, Daiana Antonia; Roat, Thaisa Cristina ; ; ; Malaspina, Osmar (Ecotoxicology and Environmental Safety, 2019) [Artigo]
Thiamethoxam (TMX) is a neurotoxic insecticide widely used for insect pest control. TMX and other neonicotinoids are reported to be potential causes of honey bee decline. Due to its systematic action, TMX may be recovered ... -
Escovopsioides as a fungal antagonist of the fungus cultivated by leafcutter ants
Osti, Julio Flavio; Rodrigues, Andre (BMC Microbiology, 2018) [Artigo]
Background: Fungus gardens of fungus-growing (attine) ants harbor complex microbiomes in addition to the mutualistic fungus they cultivate for food. Fungi in the genus Escovopsioides were recently described as members of ... -
The molecular phylogenetics of Trachymyrmex Forel ants and their fungal cultivars provide insights into the origin and coevolutionary history of 'higher-attine' ant agriculture
; ; ; ; Rodrigues, Andre; ; Bacci, Mauricio ; ; (Systematic Entomology, 2019) [Artigo]
The fungus-growing ants and their fungal cultivars constitute a classic example of a mutualism that has led to complex coevolutionary dynamics spanning c. 55-65 Ma. Of the five agricultural systems practised by fungus-growing ... -
