Conducting TIER I laboratory studies & complex higher tier studies

These are conducted under extended laboratory, semi-field and field conditions with standard or special designs. All studies are planned and performed by a highly experienced team of scientists and technical personnel according to the recent guidelines (IOBC, OECD, ISO, EPA) and guidance documents.

Non-Target Dung Organisms

We conduct studies for the testing of veterinary pharmaceuticals with dung organisms including the dung fly species Musca autumnalis and Scatophaga stercoraria, and the dung beetles Onthophagus taurus and Aphodius constans

Residue Studies

As part of a risk assessment for birds and mammals, we can conduct the determination of test item residues in food sources such as plants, earthworms and insects.
