Deadly Human-Made 'Cocktail' Threatening World’s Insect Pollinators (mostly Bees)

Tuesday, April 23, 2013 by Common Dreams
Decline of 'unsung heroes' will have drastic impacts on world's ecosystems, food supply
- Jacob Chamberlain, staff writer


A "cocktail" of human-made "pressures" are threatening insect pollinators across the world, whose decline will have "profound environmental, human health and economic consequences," according to a new report released Monday by the Insect Pollinators Initiative.

Insect pollinators such as bees provide pollination for up to 75% of crops and enable reproduction in up to 94% of wild flowering plants, meaning their current decline greatly "threatens human food supplies and ecosystem function" around the world, the group urges.

According to the study Threats to an Ecosystem Service: Pressures on Pollinators, published in Frontiers in Ecology and the Environment, the steady disappearance of these essential creatures cannot be tied to one factor, but to a multitude of anthropogenic reasons such as "the loss of food resources in intensively-farmed landscapes," pesticides, climate change, and "the spread of alien species and diseases."

Dr. Adam Vanbergen from the UK’s Center for Ecology & Hydrology and science coordinator of the IPI led the review and stated:
There is no single smoking gun behind pollinator declines, instead there is a cocktail of multiple pressures that can combine to threaten these insects. For example, the loss of food resources in intensively-farmed landscapes, pesticides and diseases are individually important threats, but are also likely to combine and exacerbate the negative impacts on pollinators.
“Pollinators are the unsung heroes of the insect world and ensure our crops are properly pollinated so we have a secure supply of nutritious food in our shops," said co-author Professor Simon Potts from the University of Reading. "The costs of taking action now to tackle the multiple threats to pollinators is much smaller than the long-term costs to our food security and ecosystem stability. Failure by governments to take decisive steps now only sets us up for bigger problems in the future.”

Wet Bugs Look Cool

Sleeping insects covered in water droplets
By Daily Mail Reporter
26th March 2010


Glistening in the early morning, these insects look like creatures from another planet as dew gathers on their sleeping bodies.

Captured in extreme close-up, one moth appears to be totally encrusted in diamonds as it rests on a twig.

Dragonflies, flies and beetles also take on an unearthly quality as the water droplets form on them.
These remarkable photographs were taken by physiotherapist Miroslaw Swietek at around 3am in the forest next to his home.
Using a torch, the 37-year-old amateur photographer hunts out the motionless bugs in the darkness before setting up his camera and flash just millimetres from them.

Mr Swietek said: 'I took up photography as a relaxing hobby two and a half years ago and I particularly like taking pictures of insects and lizards.
'I photograph them in their natural environment in the forest next to my village.

'They all are covered in dew because I go to the forest in the morning at around 3am.
'At 3am to 4am insects are sleepy and taking photos of them is easy, but it is very difficult to find them.

Shower time: Mr Swietek gets up at 3am to capture the insects while they are less active in a forest near his home
'You must be very fast taking the photos because the dew quickly disappears.
'It is very satisfying getting a good shot of an insect which I have had to hunt out.
'I have books which help my identify insects but because they are all covered in dew I find it almost impossible to know which types they are.'
Although insects do not 'sleep' in the same sense as humans, they enter a state of torpor where they are virtually immobile and much less sensitive to external stimuli.
Mr Swietek lives with his wife and teenage son in Jaroszow, a village in Poland around 30 miles from the city of Wroclaw.
