Honeybee Deaths Linked To Seed Insecticide Exposure
2012-01-13 04:31:14

Honeybee populations have been in serious decline for years, and Purdue University scientists may have identified one of the factors that cause bee deaths around agricultural fields. Analyses of bees found dead in and around hives from several apiaries over two years in Indiana showed the presence of neonicotinoid insecticides, which are commonly used to coat corn and soybean seeds before planting. The research showed that those insecticides were present at high concentrations in waste...

Image 1 - Parasitic Fly Likely Culprit in Bizarre ‘Zombie’ Bee Behavior

Scientists suspect that a parasitic fly that preys on honey bees could be the cause behind the alarming phenomenon known as colony collapse disorder (CCD), in which thousands of worker bees exhibit bizarre behavior before suddenly vanishing from their colony. Since the problem was first observed in the U.S. in 2006, experts have been attempting to explain the strange ℠zombie-like´ behavior in usually robotically predictable worker bees. European scientists have also joined in to...

Honey bee populations have been mysteriously falling for at least five years in the United States, but the cause of so-called colony collapse disorder (CCD) is still largely unknown. In a report published Nov. 2 in the online journal PLoS ONE, researchers report that a widely used in-hive medication may make bees more susceptible to toxicity of commonly used pesticides, and that this interaction may be at least partially responsible for the continuing honey bee population loss. The...

A new study reveals how enzymes in the honey bee gut detoxify pesticides commonly used to kill mites in the honey bee hive. This is the first study to tease out the precise molecular mechanisms that allow a pollinating insect to tolerate exposure to these potentially deadly compounds. The findings appear in the Proceedings of the National Academy of Sciences (PNAS). Previous studies have shown that honey bee hives are contaminated with an array of agricultural chemicals, many of which the...

Who would want to steal thousands of bees? That is what police in the Scottish region of Tayside would like to know. Four beehives containing British black bees were seen being taken away by two men from the grounds of a medical school in the city of Dundee, Reuters is reporting. Dr. Chris Connolly, the lead researcher, reported the bees missing Sunday. In a statement he described the bees as "very unique" and said they should be easy to identify if they are resold. The Center for...

Genetically modified bacteria filters out toxic vapors Genetically modified bacteria could be used in air filters to extract pesticide vapors from polluted air thanks to work by researchers in China published this month in the International Journal of Environment and Pollution. The bacteria Escherichia coli is perhaps best known as a bacterium that can cause food poisoning and in one form, the O157:H7, can damage the kidneys and even be lethal. However, E coli, is commonly used in biological...

New types of fungal pathogens, a drastic decline in the number of flowering plant species, the increased use of agricultural chemicals, and climate change are partially responsible for the worldwide plight of bee colonies, claims a new report released Thursday by the UN Environment Program (UNEP). The study, entitled Global Bee Colony Disorders and other Threats to Insect Pollinators, fingers more than a dozen possible factors, all of which have contributed in some way to the decline of the...

Scientists are seeking a way to identify and eliminate mass deaths of the honeybee, the primary pollinator for the world's plants. The die-offs affect more than 30 percent of bee colonies in the United States and more than 20 percent in some European countries. A few possible causes identified in Colony Collapse Disorder (CCD) include blood-feeding parasites, bee viruses, fungi, pesticide exposure and decreased plant diversity causing poor nutrition for honeybees, experts tell Reuters....

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
