Research suggests that warmer fall seasons may lead to colony collapse in honey bees due to increased flying time. However, cold storage for colonies could help reduce the risk of colony collapse by allowing bees to cluster earlier and save workers.
A new study by Penn State researchers found that US honey bee colony loss is primarily related to parasitic mites, extreme weather events, and nearby pesticides. The study integrated multiple large datasets at different spatial and temporal resolutions to assess various potential stressors associated with colony collapse across the US.
Scientists analyzed the virus' course of action and discovered how it captures host ribosomes using a structured RNA sequence called IRES. This finding advances research into feeding bees RNA molecules that interfere with the virus's RNA, potentially offering a solution to Colony Collapse Disorder.
The study found that the supply of queens and packaged bees is sufficiently elastic to absorb demand increases due to colony collapse disorder, leading to no significant price hikes. Beekeeper methods of offsetting winter losses, such as splitting hives, remained relatively inexpensive and effective in meeting pollination contracts.
The largest king penguin colony on Île aux Cochons has plummeted in size by nearly 90%, with researchers attributing the decline to climate change and vegetation encroachment. Satellite images reveal that the colony's population began declining in the late 1990s, coinciding with a major climatic event related to El Niño.
Researchers at Michigan State University have discovered four genes that help Varroa mites survive and two that affect their reproduction. The team used RNA interference to identify the key genes, which could lead to reduced or eliminated mite populations. This breakthrough may also have applications beyond bee conservation.
UK scientists found that widely-used agricultural insecticides like neonicotinoids may not be the primary cause of honeybee colony collapse. Researchers repeated a flawed calculation and used a realistic birth rate, revealing the risk of colony collapse under pesticide exposure disappears.
A new study from Harvard School of Public Health finds a link between imidacloprid and Colony Collapse Disorder (CCD) in honeybees. The researchers discovered that even low levels of the pesticide can cause hive collapse, highlighting the potential impact on agriculture.
A Texas Tech University biologist has identified a possible cause of the sudden death of bee colonies across North America: a combination of an insect virus and a fungus. The researchers' study published in PLOS ONE found an association between the two pathogens and high mortality rates among bees.
Researchers discover Israeli Acute Paralysis Virus (IAPV) significantly associated with colony collapse disorder (CCD) in honey bee colonies. IAPV was found in all four affected operations and correctly distinguished CCD from non-CCD status 96.1% of the time.
A study published by AAAS suggests that Israeli Acute Paralysis Virus (IAPV) is a potential cause of Colony Collapse Disorder (CCD), a phenomenon where adult bees disappear from hives. Researchers found molecular signs of IAPV associated with CCD, but stressors like poor nutrition and pesticide exposure are also likely involved.
