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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
