3.1.4. Marking techniques

Experimental purposes often require cohort-specific or individual marking of SHB, e.g. for behavioural studies (see the BEEBOOK paper on behavioural methods by Scheiner et al., 2013). Therefore various marking techniques employing dyes, food colouring, dusting, and thoracic notching have been attempted in SHB larvae and adults with different levels of persistence and mortality.
