A new formulation of oxalic acid for Varroa destructor control applied in Apis mellifera colonies in the presence of brood
(2016-07)An organic product based on oxalic acid was evaluated for use in Varroa control under spring/summer climatic conditions in Argentina. The formulation consists of four strips made of cellulose impregnated with a solution ... -
Las abejas melíferas (Apis mellifera L) y su desempeño como insectos polinizadores en kiwi (Actinidia chinensis var. Deliciosa)
(Sociedad Argentina de Apicultores, 2020-10)El cultivo de kiwi (Actinidia chinensis var. deliciosa cv Hayward) presenta gran importancia en la zona del sudeste de la provincia de Buenos Aires (desde El Dorado, Sierra de los Padres, Mar del Plata, Batán, Miramar, ... -
Contribution of honeybees to soybean yield
(Springer, 2018-02)Despite the economic importance of soybean [Glycine max (L.) Merr.], knowledge on the contribution of entomological pollination on seed yield is scarce. This study estimates the production of soybean resulting from pollination ... -
Determination of imidacloprid in beehive samples by UHPLC-MS/MS
(2018)Imidacloprid is a systemic insecticide belonging to the neonicotinoid family. It was the first neonicotinoid introduced in the mid-1990s, and since then, its use has grown rapidly to control pests in a variety of agricultural ... -
Differentiation of argentine propolis from different species of bees and geographical origins by UV spectroscopy and chemometric analysis
(Elsevier, 2018-09)Bees collect vegetal resins that they mix with their wax and mechanical impurities to elaborate propolis, whose chemical composition is complex and variable depending on botanical/geographical origin, type of bee, time of ... -
Distribution and prevalence of Nosema apis and N. ceranae in temperate and subtropical eco-regions of Argentina
(2016-11)A total of 361 colonies from 59 apiaries located in two temperate and three subtropical eco-regions were examined during the post-harvest period to determine distribution and prevalence of Nosema spp. Apiaries from subtropical ... -
Effect of environmental factors on bee activity and onion (Allium cepa L.) seed yield = Efecto de factores ambientales en la actividad de la abeja y en el rendimiento de semilla de cebolla (Allium cepa L.)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-12)Pollinators are required to produce onion seeds. This specie is one of the main vegetable crops. Two types of onion varieties are mainly grown worldwide: hybrids and open pollination (OP) cultivars. Although hybrids offer ... -
Environment and Varroa destructor management as determinant of colony losses in apiaries under temperate and subtropical climate
(2018-07)For the last 10 years, honey bee colony losses have been a topic of interest for researchers around the world, and many drivers for losses were described. The aim of this study was to evaluate the risk factors associated ... -
Estudio de los factores de riesgo asociados a la presencia y difusión de la Varroosis en la Provincia de Santa Fe
(Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, 2015)Varroa destructor (Anderson and Trueman) (Acari: Varroidae) es un ectoparásito obligado de Apis mellifera L. (Hymenoptera: Apidae) y es considerado una de las mayores amenazas a la producción apícola global. El daño causado ... -
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 ... -
Fumagillin control of Nosema ceranae (Microsporidia:Nosematidae) infection in honey bee (Hymenoptera:Apidae) colonies in Argentina
(2016)Information on the long‑term consequences of Nosema ceranae to honey bee lifespan and effectiveness of Nosema control with fumagillin is scarce and not always consistent. Our objective in this study was to evaluate the ... -
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 ... -
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 ... -
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 ... -
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 ... -
