A longitudinal study was carried out in order to evaluate Nosema spp. spore counts two key moments of the year (late autumn and spring) honeybee colonies from five eco-regions Argentina. Three hundred sixty were randomly selected infestation level Varroa destructor assessed spring 2015. In addition, a questionnaire concerning all management practices applied answered by beekeepers. Generalized ...
In ecosystems, a variety of biological, chemical and physical stressors may act in combination to induce illness in populations of living organisms. While recent surveys reported that parasite-insecticide interactions can synergistically and negatively affect honeybee survival, the importance of sequence in exposure to stressors has hardly received any attention. In this work, Western honeybees...
In New Zealand, the introduced honey bee (Apis mellifera) is a valuable production animal, providing pollination services for horticultural crops and significant export volumes of honey, especially mānuka honey. Honey bees in Zealand are free from number diseases pests such as European foulbrood, acarine disease, small hive beetle, Israeli acute paralysis virus tropilaelaps mites. We sought to ...
Beekeeping, performed in many parts of the world, has a very large place world trade market with bee products such as wax, venom, propolis and royal jelly, especially honey production. However, diseases are quite common restricted production products. One most important these diseases, Nosema, is caused by spores intestinal epithelium cells honeybee. Nosema apis ceranae factors this disease als...
Parasites, by altering the nutritional and energetic state of their hosts, can significantly alter their foraging behaviour. In honeybees, an infection with Nosema ceranae has been shown to lower the energetic state of individual bees, bringing about changes in behaviours associated with foraging. Comparing the foraging trip times, hive times in between trips, and the crop contents of uninfecte...
