Transmission of viruses between eastern and western honey bees are rare
Interspecific transfers of viruses between the western honey bee (Apis mellifera) and the eastern honey bee (Apis cerana) are rare, even if honey bees are kept in close proximity, new research reveals. Ref. Source 5z.
First multi-year study of honey bee parasites and disease reveals troubling trends
Researchers in the United States recently completed the first comprehensive, multi-year study of honey bee parasites and disease as part of the National Honey Bee Disease Survey. The findings reveal some alarming patterns, but provide at least a few pieces of good news as well. Ref. Source 2i.
Pesticides used to help bees may actually harm them
Honeybees from chlorothalanil-treated hives showed the greatest change in gut microbiome, a new study has concluded. The discovery is a concern because alterations can affect the gut's ability to metabolize sugars and peptides, processes that are vital for honeybee health. Beekeepers typically apply pesticides to hives to rid them of harmful parasites such as Varroa mites. Ref. Source 1g.
Queens, sex and colony collapse
When a queen has sex with many different partners, it can increase her risk of infection with venereal disease. It can also lead to the collapse of her colony. This might read like ingredients for a juicy novel, but for bees it is reality. Ref. Source 3w.
High number of pesticides within colonies linked to honey bee deaths
Honey bee colonies in the United States have been dying at high rates for over a decade, and agricultural pesticides -- including fungicides, herbicides and insecticides -- are often implicated as major culprits. Until now, most scientific studies have looked at pesticides one at a time, rather than investigating the effects of multiple real-world pesticide exposures within a colony. Ref. Source 4k.
We only have ourselves to blame for the terrible things done to the creatures of this earth. Bees have to battle radio signals, invasion of their hive by humans for their honey and pesticides (Other chemicals) just to live.
New findings about the deformed wing virus, a major factor in honey bee colony mortality
In recent years, massive losses of honey bee colonies have occurred during winter in Europe and North America. It could be shown that the Varroa mite and the deformed wing virus are the main factors responsible for the alarming bee mortality. Researchers have succeeded for the first time in simulating the course of disease using artificial genetic material of the virus. Ref. Source 5v.
