The use of test syrups

There are multiple reasons for using syrups (sugar water) in the study of honey bee colonies. In this section, we will only focus on syrup use to study pesticide effects on colony or pesticide repartition within the colony. The use of syrup to distribute an AI for varroa control such as the trickling method (pouring syrup directly onto the bees between the frame spaces with a syringe) will not be reviewed but can be found in Dietemann et al., 2012.
