Widespread impacts of neonicotinoids 'impossible to deny'

RATE THIS! +39
Posted in Science on 24th Jun, 2014 11:58 PM by AlexMuller

Neonicotinoid pesticides are causing damage to a range of beneficial species and are a key factor in the decline of bees. Researchers, who have carried out a four-year review of the literature, say the evidence of damage is now "conclusive". The scientists say the threat to nature is the same as that once posed by the notorious chemical DDT. 

 

Manufacturers say the pesticides are not harming bees or other species. Neonicotinoids were introduced in the early 1990s as a replacement for older, more damaging chemicals. They are a systemic insecticide, meaning that they are absorbed into every cell in a plant, making all parts poisonous to pests. But some scientists have been concerned about their impact, almost since the moment they were introduced.

 
Much of the worry has surrounded their effects on bees. There's been a well documented, global decline in these critical pollinators. Many researchers believe that exposure to neonicotinoids has been an important destabilising factor for the species.

Decline of bees has received a lot of attention and research. This is quite understandable considering that bees are critical for wildlife and agriculture. Now is the time to evaluate the data coming out from research and reduce and eliminate pesticide - we can not wait to see more definite studies Reply

The problem of immediate halt is that with neonicotinoids and fipronil making up around a third of the world market in insecticides, farmers are over-relying on them in the same way as they once became over reliant on chemicals like DDT.

The difference is that neonicotinoids don't accumulate in human or animal tissue in the way that DDT once did. However, the modern pesticides are more lethal, about 6,000 times as toxic compared to the older spray. Reply
