Pesticides (neonicotinoids) and Bee Behaviour
3 August 2013
A science experiment showing the effect of pesticides (neonicotinoids) on bee behaviour. From the BBC Horizon documentary titled What’s Killing Our Bees?
From Wildlife Extra:
Neonicotinoids do cause significant damage to ecosystem
For the first time scientists say they are able to provide conclusive evidence that the systemic pesticides neonicotinoids and fipronil (neonics) have caused significant damage to a wide range of invertebrates, including bees.
The IUCN Task Force Systemic Pesticides (a group of global, independent scientists) analysed 800 peer-reviewed reports.
They found that there is clear evidence of a serious risk to honeybees and other pollinators such as butterflies and to a wide range of other invertebrates such as earthworms and vertebrates including birds.
“The evidence is very clear. We are witnessing a threat to the productivity of our natural and farmed environment equivalent to that posed by organophosphates or DDT,” said lead author Dr Jean-Marc Bonmatin of The National Centre for Scientific Research in France.
The most affected groups appeared to be terrestrial invertebrates such as earthworms which are exposed at high levels in soil and plants.
The next most affected group is insect pollinators such as bees and butterflies which are exposed to high contamination through air and plants and medium exposure levels through water.
Bird populations are also at risk from eating crop seeds treated with systemic insecticides, and reptile numbers have declined due to depletion of their insect prey.
“The findings of the WIA are gravely worrying,” said Maarten Bijleveld van Lexmond, Chair of the Task Force.
“We can now clearly see that neonics and fipronil pose a risk to ecosystem functioning and services which go far beyond concerns around one species and which really must warrant government and regulatory attention.”
