Autor: Ernesto Guzman-Novoa, Miguel Corona, Mohamed Alburaki, Francisco José Reynaldi, Ciro Invernizzi, Gregorio Fernández de Landa, Matías Maggi

Publikováno v: Frontiers in Ecology and Evolution, Vol 12 (2024)

The honey bee (Apis mellifera) parasitic mite, Varroa destructor, is considered one of the main causes of colony losses in European honey bee (EHB) populations around the world. However, some EHB and Africanized honey bee (AHB) populations (derived f

Autor: Christiane Düttmann, Byron Flores, Jessica Sheleby-Elías, Gladys Castillo, Daymara Rodriguez, Matías Maggi, Jorge Demedio

Publikováno v: PLoS ONE, Vol 17, Iss 4 (2022)

Various subspecies of Apis mellifera L. were introduced to Central America since colonization 500 years ago. Hybridization increased with the entrance of the Africanized bee in Nicaragua in 1984. Rustic beekeeping activities and numerous feral swarms

Publikováno v: Revista de la Sociedad Entomológica Argentina, Vol 78, Iss 1 (2019)

La transmisión de virus por Varroa destructor Anderson & Trueman a las abejas ha sido identificada como una de las principales amenazas para las colonias de Apis mellifera L. También se ha sugerido que la interacción sinérgica entre parásitos y

Publikováno v: Insects, Vol 10, Iss 10, p 329 (2019)

In temperate climates, beekeeping operations suffer colony losses and colony depopulation of Apis mellifera during overwintering, which are associated with biotic and abiotic stressors that impact bees’ health. In this work, we evaluate the impacts

Dietary Supplementation of Honey Bee Larvae with Arginine and Abscisic Acid Enhances Nitric Oxide and Granulocyte Immune Responses after Trauma

Autor: Pedro Negri, Leonor Ramirez, Silvina Quintana, Nicolás Szawarski, Matías Maggi, Yves Le Conte, Lorenzo Lamattina, Martin Eguaras

Publikováno v: Insects, Vol 8, Iss 3, p 85 (2017)

Many biotic and abiotic stressors impact bees’ health, acting as immunosupressors and contribute to colony losses. Thus, the importance of studying the immune response of honey bees is central to develop new strategies aiming to enhance bees’ fit
