A team of PoshBee researchers lead by Prof. Alexandra-Maria Klein from the University of Freiburg, Germany, performed field and semi-field experiments aiming to measure the effect of chemicals and their interactions with other stressors on bees.

 

The field experiments were undertaken in an apple orchard near lake Constanz (Germany). The researchers observed honeybees, bombus bees, and mason bees.

For the purpose of the semi-field experiments large spaces covered with a net were built where different types of environments were created for bees. The team performed colony assessment and collected data for bombus bees, flower visiting, they extracted haemolymph from bees, etc.
