Pesticidas banidos em 2013 não afectam de igual modo as abelhas - Estudo
http://www.bbc.com/news/science-environment-36154134
Citando:
"This study examined the three types banned by the EU in 2013. It shows that different types affect the brains of bumblebees in distinct ways.
Two (imidacloprid and thiamethoxam) were shown to be highly toxic to bumblebees when they were exposed to levels of the chemicals found in the countryside.
They affected their brains, impairing their memory and ability to forage for pollen. The toxic effects also included altering the make-up of the colony, changing the ratio of males to females and in some cases reducing the number of queens.
The third (clothiandin) - a close chemical relative that has not been tested before is shown not to be harmful to bees in the low doses given during field trials. The number of queens in the colonies actually increased."
