Parasitism and bees: a concept revision from an ecological perspective. From the beginning all, parasites, pathogens and viruses are organisms that have a negative connotation in the field of medicine. However, the use of methodologies and terms of medicine in the field of ecology and, above all, veterinary medicine, led to this understanding of "p...
El ectoparásito de Apis mellifera, Varroa destructor, es uno de los principales problemas para la apicultura mundial. La siguiente revisión indaga en investigaciones relacionadas con la parasitosis, con principal hincapié en los estudios llevados a cabo en Latinoamérica. Desde los primeros registros de la parasitosis y hasta la actualidad, se prese...
Varroa destructor is a parasitic mite, which is considered a severe pest for honey bees causing serious losses to beekeeping. Residual hydrolats from steam extraction of hop essential oils, generally considered as a waste product, were tested for their potential use as acaricides on V. destructor. Four hop varieties, namely Cascade, Spalt, Victoria...
Due to the complex interactions between pathogens and environmental and anthropogenic stressors, in temperate climates, honey bee populations suffer depopulation and/or colony death, mainly during overwintering. Nosema spp. comprises one of the primary pathogens affecting Apis mellifera colonies, and cold ambient temperature promotes its intensity...
Varroosis is a disease caused by the mite Varroa destructor, and it is considered one of the biggest threats to honey bee populations globally. Mite control is centered on the use of synthetic acaricides, such as amitraz and flumethrine. However, high usage of these chemicals is associated with a wide variety of undesirable effects on bee colonies,...
In the late winter or early spring, beekeepers stimulate the colonies to increase the population of bees using different dietary supplements, principally based on carbohydrates and proteins. Honey bees require multiple sources of nectar and pollen to obtain balanced nutrition, so the formulation of effective supplements requires the identification...
Humulus lupulus, commonly known as hops has widely been used in breweries globally, however, the acaricidal properties of H. lupulus derived products could also be a novel and interesting avenue of study against insect pests. We tested the antiparasitic activity of H. lupulus essential oils against the honeybee mite Varroa destructor, and its bioac...
Efecto del ácido giberélico en la producción de celdas reales y el rendimiento de la reina en colonias de Apis mellifera L. (Hymenoptera: Apidae) RESUMEN. Para la abeja melífera (Apis mellifera L.), la recompensa por la polinización es la obtención de alimento: néctar, una solución azucarada, o polen, que contiene un alto porcentaje de proteínas y...
Para la abeja melífera (Apis mellifera L.), la recompensa por la polinización es la obtención de alimento: néctar, una solución azucarada, o polen, que contiene un alto porcentaje de proteínas y lípidos. También hay otras recompensas florales ecológicamente

The ectoparasitic mite Varroa destructor is potentially the greatest threat to honey bee colonies of Apis mellifera worldwide. Acaricide rotation is widely accepted to mitigate development of resistance to synthetic acaricides. When a population has developed resistance to a compound, cessation of its use can result in some degree of susceptibility...
