The Buzz about Honey Bee Viruses
High annual losses of honey bees, as well as range reductions and local extinctions of wild and native pollinator species, are concerning because bees are important plant pollinators [1]. Approximately one-third of the typical Western diet requires bee pollination, and honey bees (Apis mellifera) are the primary pollinators of numerous food crops, including fruits, nuts, vegetables, and oilseed...
متن کاملHoney bee (Apis mellifera) colony health and pathogen composition in migratory beekeeping operations involved in California almond pollination
Honey bees are important pollinators of agricultural crops. Pathogens and other factors have been implicated in high annual losses of honey bee colonies in North America and some European countries. To further investigate the relationship between multiple factors, including pathogen prevalence and abundance and colony health, we monitored commercially managed migratory honey bee colonies involv...
متن کاملParasite Pressures on Feral Honey Bees (Apis mellifera sp.)
Feral honey bee populations have been reported to be in decline due to the spread of Varroa destructor, an ectoparasitic mite that when left uncontrolled leads to virus build-up and colony death. While pests and diseases are known causes of large-scale managed honey bee colony losses, no studies to date have considered the wider pathogen burden in feral colonies, primarily due to the difficulty...
متن کاملEvidence for emerging parasites and pathogens influencing outbreaks of stress-related diseases like chalkbrood.
In agriculture, honey bees play a critical role as commercial pollinators of crop monocultures which depend on insect pollination. Hence, the demise of honey bee colonies in Europe, USA, and Asia caused much concern and initiated many studies and research programmes aiming at elucidating the factors negatively affecting honey bee health and survival. Most of these studies look at individual fac...
متن کاملHoney Bee-Infecting Plant Virus with Implications on Honey Bee Colony Health
Honey bees are eusocial insects that are commercially managed to provide pollination services for agricultural crops. Recent increased losses of honey bee colonies (averaging 32% annually since 2006) are associated with the incidence and abundance of pathogens. In their study in mBio, J. L. Li et al. [mBio 5(1):e00898-13, 2014, doi:10.1128/mBio.00898-13] share their discovery that a plant virus...
