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 ... -
Honeybees generalize among pollen scents from plants flowering in the same seasonal period
(The Company of Biologists, 2019-11)When honey bees (Apis mellifera) feed on flowers, they extend their proboscis to absorb the nectar, i.e. they perform the proboscis extension response (PER). The presence of pollen and/or nectar can be associated with ... -
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 ... -
Key management practices to prevent high infestation levels of Varroa destructor in honey bee colonies at the beginning of the honey yield season
(2016)Varroa destructor is considered one of the main threats to worldwide apiculture causing a variety of physiological effects at individual and colony level. Also, Varroa mites are often associated with several honey bee ... -
Managed honeybee hives and the diversity of wild bees in a dryland nature reserve
(Springer, 2021)Honeybee hives may influence pollen and nectar availability in natural ecosystems, which may consequently affect wild pollinators. We studied the effects of managed honeybee hives on wild bee diversity in Villavicencio ... -
Molecular characterization of Apis mellifera colonies from Argentina: genotypic admixture associated with ecoclimatic regions and apicultural activities
(Wiley Online Library, 2018-08)The European honeybee, Apis mellifera L. (Hymenoptera: Apidae), is considered as a main contributor to pollination of important crops and to honey production. Originally, beekeeping in Argentina was performed in an extended ... -
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 ... -
Multiresidue method for trace pesticide analysis in honeybee wax comb by GC-QqQ-MS
(2017-01-15)The aim of this analytical study is to develop an improved multi-residue methodology of high sensitivity and expanded scope for pesticide residue analysis in honeybee wax combs. The method was validated for 160 pesticide ... -
Nectar and flower traits of different onion male sterile lines related to pollination efficiency and seed yield of F1 hybrids
(Entomological Society of America, 2013-06)Honey bees are the main pollinators of onion crops for seed production, but owing to low attractiveness of flowers, pollination is often inadequate. Pollination problems result in low seed yields. This problem is accentuated ... -
Observaciones preliminares del efecto del tamaño de celdas en los niveles de infestación de Varroa destructor sobre abejas Apis mellifera
(EEA Reconquista, 2018-06)En el relevamiento realizado por INTA Centro Regional Santa Fe durante 2015 en toda la provincia, se describe que la prevalencia de adultos con V. destructor en colmenas con más de 3% de infestación, parece estar asociada ... -
Potential associations between the mite Varroa destructor and other stressors in honeybee colonies (Apis mellifera L.) in temperate and subtropical climate from Argentina
(2018-09-14)The presence of Varroa destructor in colonies of Apis mellifera is explained by the interaction among a number of factors including beekeeping practices and surrounding environment features. The aim of this study was to ... -
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 ... -
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 ... -
Risk factors associated with failures of Varroa treatments in honey bee colonies without broodless period
(2015-09)The treatment against Varroa destructor has become a basic tool in beekeeping practices, mainly during autumn. The treatment effectiveness should be improved by identifying variables affecting the final outcome. The aim ... -
Risk factors associated with the presence of Varroa destructor in honey bee colonies from east-central Argentina
(2014-08-01)Varroa destructor is considered one of the major threats for worldwide apiculture. Damage caused by varroa mite includes body weight loss, malformation and weakening of the bees. It was also suggested as the main cause ... -
Screening of pesticide residues in honeybee wax comb by LC-ESI-MS/MS. A pilot study
(2016-11)A developed multi-residue method using microflow-LC-ESI-QqQ-MS provided a wide-scope analysis for medium-polar and polar pesticide residues (120 compounds including breakdown products). Honeybee wax comb samples were ... -
