Age‑performance and intensity of grooming behavior toward Varroa destructor in resistant and susceptible Apis mellifera colonies
(Springer, 2022-10)Grooming behavior confers resistance to honey bees against Varroa destructor, being of interest to social immunity studies and breeding programs. The objective of this study was to characterize at the individual level the ... -
Agricultural intensification impairs behavioral abilities and the expression of genes associated with social responsiveness in honeybees
(Cell Press, 2024-08-12)The honeybee Apis mellifera is one of the main pollinators in agroecosystems, and, consequently, its colonies are exposed to agrochemicals and more fragmented and homogeneous habitats. As a social insect, this could lead ... -
Bacterially expressed dsRNA induces Varroa destructor gene knockdown by honey bee-mediated oral administration
(Taylor and Francis, 2022-02)The ectoparasite Varroa destructor causes serious losses of Apis mellifera colonies and negatively impacts the beekeeping industry around the world. New control methods have been proposed based on the RNA interference ... -
Complete genome sequence of deformed wing virus and black queen cell virus isolated from honeybees (Apis mellifera) in Argentina
(American Society for Microbiology, 2024-03)We report the complete genome sequence of deformed wing virus and black queen cell virus isolated from Argentinean’s honeybees. These sequence data will be valuable for future research on the viral variants present in the ... -
Defensive Behavior and Morphometric Variation in Apis mellifera Colonies From Two Different Agro-Ecological Zones of North-Western Argentina
(Frontiers Media, 2021-09-14)European lineages of Apis mellifera were first introduced into America for beekeeping purposes. A subsequent introduction and accidental release of A. m. scutellata resulted in hybridization events that gave rise to ... -
Detection and characterization of Deformed Wing Virus (DWV) in apiaries with stationary and migratory management in the province of Entre Ríos, Argentina
(Springer Nature, 2024-07)In Argentina, migratory activity in search of floral diversity has become a common approach to maximizing honey production. The Entre Ríos province possesses a floral diversity that allows beekeepers to perform migratory ... -
Development of a loop-mediated isothermal amplification (LAMP) and a direct LAMP for the specific detection of Nosema ceranae, a parasite of honey bees
(Springer, 2020-10)Nosema ceranae is a ubiquitous microsporidian pathogen infecting the midgut of honey bees. The infection causes bee nosemosis, a disease associated with malnutrition, dysentery, and lethargic behavior, and results in ... -
Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Grooming Behavior in Naturally Varroa-Resistant Apis mellifera Colonies From North-Central Argentina
(Frontiers Media, 2020-10-22)The Western honey bee, Apis mellifera, is an important species in providing honey and pollination services globally. The mite Varroa destructor is the major threat to A. mellifera, and it is associated with the severe ... -
El grooming: enemigo de la varroa
(Sociedad Argentina de Apicultores, 2021-07)Una de las enfermedades que mayores pérdidas ocasiona a la industria apícola es la Varroosis, causada por el ácaro Varroa destructor. La selección de colonias por el comportamiento de grooming puede ser una respuesta a ... -
Individual precocity, temporal persistence, and task-specialization of hygienic bees from selected colonies of apis mellifera
(2016)Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colonylevel and is explained by the proportion ... -
Molecular detection and differentiation of arthropod, fungal, protozoan, bacterial and viral pathogens of honeybees
(MDPI, 2022-05)The honeybee Apis mellifera is highly appreciated worldwide because of its products, but also as it is a pollinator of crops and wild plants. The beehive is vulnerable to infections due to arthropods, fungi, protozoa, ... -
Morphometric and genetic characterization as tools for selection of Apis mellifera (Hymenoptera: Apidae) stocks in an area of natural hybridization in Argentina
(Frontiers Media, 2023-01)Beekeepers around the world select bees’ characteristics that facilitate and favor production. In regions where hybridization among lineages is taking place, this selection is a challenge, given that these regions are ... -
Preliminary report of the toxicity of Lippia junelliana (Lamiales: Verbenaceae) and Elionorus muticus (Poales: Poaceae) on Apis mellifera (Hymenoptera: Apidae)
(Sociedad Entomológica Argentina, 2022-01)Several phytochemicals, such as extracts and essential oils, are among the ecological alternatives that have been studied for the control of pathogens that affect humans, animals, and plants. Essential oils are aromatic ... -
Temporal changes in volatile profiles of Varroa destructor-infested brood may trigger hygienic behavior in Apis mellifera
(Wiley, 2021-03-16)Varroa destructor Anderson & Trueman (Acari: Varroidae) is one of the major contributors to the significant losses of western honey bee, Apis mellifera L. (Hymenoptera: Apidae), colonies worldwide. Hygienic behavior, in ... -
Varroa destructor parasitism and genetic variability at honey bee (Apis mellifera) drone congregation areas and their associations with environmental variables in Argentina
(Frontiers Media, 2020-11)Varroa destructor is a serious ectoparasite of the western honey bee, Apis mellifera, which negatively impacts on colonies health and survival worldwide. Drone-mediated movement and the presence of the mite in Drone ...
