Polydomy in the ant Ectatomma opaciventre
(Journal of insect science (Online), 2014) [Artigo]Tropical ants commonly exhibit a hyper-dispersed pattern of spatial distribution of nests. In polydomous species, nests may be satellites, that is, secondary structures of the main nest, where the queen is found. In order ... -

Aggressiveness in honeybees seems to be regulated by multiple genes, under the influence of different factors, such as polyethism of workers, environmental factors, and response to alarm pheromones, creating a series of ... -
Increase in scout trips due to forager removal in Atta sexdens (Hymenoptera, Formicidae) (Forel, 1908)
Brugger, Mariana Silva; Camargo, Roberto da Silva ; Forti, Luiz Carlos ; (Behavioural Processes, 2018) [Artigo]
Social information exchange through physical contacts and chemical trail deposition forms the basis of food recruitment in leaf-cutting ants. The scout initiates the process and passes the information to nestmates that ... -
Acid, alkali and peroxide pretreatments increase the cellulose accessibility and glucose yield of banana pseudostem
Shimizu, Felipe Lange; ; Ghiraldi, Pedro Henrique Ciconello ; Melati, Ranieri Bueno ; Pagnocca, Fernando Carlos ; ; ; Brienzo, Michel (Industrial Crops and Products, 2018) [Artigo]
Lignocellulosic biomasses such as banana pseudostem are attractive cellulose sources for bioenergy production, and for the use in biorefinery processes. However, pretreatment of lignocellulosic material is required to ... -

For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by ... -
De novo transcriptome assembly: a new laccase multigene family from the marine-derived basidiomycete Peniophora sp. CBMAI 1063
Otero, Igor Vinicius Ramos; Ferro, Milene ; Bacci, Maurício ; Ferreira, Henrique ; Sette, Lara Durães (AMB Express, 2017) [Artigo]
Laccases are multicopper oxidases that are able to catalyze reactions involving a range of substrates, including phenols and amines, and this ability is related to the existence of different laccases. Basidiomycetes usually ... -
Phospholipase A1-based cross-reactivity among venoms of clinically relevant Hymenoptera from Neotropical and temperate regions
Perez-Riverol, Amilcar; ; ; dos Santos-Pinto, José Roberto Aparecido ; ; Izuka Moraes, Gabriel Hideki ; ; ; ; Palma, Mario Sergio et al. (Molecular Immunology, 2018) [Artigo]
Molecular cross-reactivity caused by allergen homology or cross-reactive carbohydrate determinants (CCDs) is a major challenge for diagnosis and immunotherapy of insect venom allergy. Venom phospholipases A1 (PLA1s) are ... -
