09_06_2016, Cristina Botias, Quantifying exposure of bees to pesticides

Subido por ebddsa dsa, 10/06/16 15:03
In recent years, an intense debate has been generated about the environmental risks posed by neonicotinoids, a group of widely-used, neurotoxic insecticides. When these systemic compounds are applied to seeds low concentrations are subsequently found in the nectar and pollen of the crop and so they can be consumed by bees. A key point of controversy is whether bees consume enough of these compounds during the flowering period of the crop to do them significant harm. Thus, there is a need to understand the routes of exposure for bees and the levels present in the pollen and nectar of the flowers they visit. In this seminar I will show the concentrations of neonicotinoid insecticides that bees are exposed to when they forage in agricultural landscapes, and I will comment on the work in progress where I am assessing the effect of field-realistic levels of pesticides on bumblebee colonies.
