Eurofins Agroscience Services perform semi-field studies on honey bee (Apis mellifera L) in test tents with a crop area of 20 to 180 m2. Our experience goes from standard studies where we evaluate the acute toxicity of a test item applied to an attractive crop, to special studies where we evaluate for example the possible risk to the honey bee brood, sublethal effects on bees and residues in bees and their products.
