A method for semi-field rearing of Varroa destructor (Acari: Varroidae) to obtain mites of controlled age and specific life cycle
(Les Amis d'Acarologia, 2023-03)Varroa destructor is one of the most devastating ectoparasites of the honey bee, Apis mellifera, worldwide. Given that V. destructor has very low survivability and exhibits no successful reproduction away from their natural ... -
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 ... -
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 ... -
Embryogenesis and apoptosis appears as key molecular pathways involved in Varroa destructor reproduction
(Springer, 2023-10)In this study, we identified candidate genes associated with the reproductive success of Varroa destructor in Apis mellifera brood cells at a key point in time, the 4th day after host cell capping. First-life cycle reproducing ... -
Environmental conditions and beekeeping practices associated with Nosema ceranae presence in Argentina
(Springer, 2021-01)A longitudinal study was carried out in order to evaluate Nosema spp. spore counts in two key moments of the year (late autumn and spring) in honeybee colonies from five eco-regions of Argentina. Three hundred and sixty ... -
Field evaluation of Varroa-resistance traits in surviving Apis mellifera colonies in Argentina
(Springer, 2021-10)Varroa destructor is one of the most important sanitary threats for the beekeeping industry and so far disease control is based mainly on chemical treatment. However, a long-term solution may arise from studying natural ... -
Genetic variation and heteroplasmy of Varroa destructor inferred from ND4 mtDNA sequences
(Springer, 2020-02)Varroa destructor, a parasitic mite of the western honey bee, Apis mellifera L., is a serious threat to colonies and beekeeping worldwide. Population genetics studies of the mite have provided information on two mitochondrial ... -
Prevalence of honey bee (Apis mellifera) viruses in temperate and subtropical regions from Argentina
(2017)In Argentina, bee virus studies are still incipient, and there are no studies regarding the climatic effect. The aim of this study was to assess and compare the presence of honeybee viruses in different climatic regions ... -
Short communication: Varroa destructor re-invasion dynamics during autumn and winter in Apis mellifera colonies from a temperate climate
(Elsevier, 2023-03)Infestation with Varroa destructor compromises the survival of Apis mellifera colonies, especially during the winter season. In order to prevent colony losses due to the presence of Varroa mites, determination of the ... -
Varroa destructor and Nosema sp seasonal dynamics in Apis mellifera colonies from temperate climate in Argentina = Dinámica estacional de Varroa destructor y Nosema sp en colonias de Apis mellifera en clima templado de Argentina
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2022)Los ectoparásitos obligados Varroa destructor y Nosema sp afectan la salud de la abeja de la miel Apis mellifera y genera importantes pérdidas de la colonia. Este artículo describe y analiza información proveniente de ... -
Varroa destructor and viruses association in honey bee colonies under different climatic conditions
(2016-06)Honey bee colonies are threatened by multiple factors including complex interactions between environmental and diseases such as parasitic mites and viruses. We compared the presence of honeybee-pathogenic viruses and Varroa ...
