For antibiotic studies

When experiments are set to study antibiotics, they usually aim at documenting the repartition of antibiotic residues within the apicultural matrices. Antibiotics are mixed with syrup made usually with sucrose. Syrup can be poured into frames (Adams et al., 2007), or fed to the colony with through feeders. Control colonies are fed with non-supplemented syrup (Martel et al., 2006).
