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 ... -
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 ... -
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 ... -
Standard methods for fungal brood disease research = Métodos estándar para la investigación de enfermedades fúngicas de la cría
(Taylor & Francis, 2013)Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and ... -
Strategic use of honey bees (Apis mellifera L.) to increase the number and size of fruits in kiwifruit (Actinidia chinensis var. deliciosa)
(Elsevier, 2022-02)Fruit size in kiwifruit depends mainly on the number of seeds or fertilized ovules. Pollination by wind is not enough to obtain a fruit size accepted by the market, so it is necessary to perform this practice by means of ... -
Sublethal exposure to imidacloprid in commercial Apis mellifera colonies in early spring: performance of honey bees and insecticide transference between in-hive products
(Springer, 2023-04)Honey bees have an important role in ecosystems as pollinators. However, in recent years, bee populations have declined, with habitat destruction, pesticide use, and climate change contributing to the decline. One of the ... -
Valle de Uco. Prevalencia de Varroa destructor en el periodo 2016-2017
(INTA. Programa Nacional de Apicultura (ProApi), 2017)El informe describe los factores climáticos que perjudicaron la última temporada apícola y enumera las múltiples causas que atentan contra las poblaciones de abejas, volviéndolas más susceptibles a enfermedades. Asimismo, ... -
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 ...
