2.2.3. Weighing of adult honey bees
The fresh weight of adult bees is a measure for nutritional and health state and can be measured from live (see section 2.1. on immobilising honey bees) or dead honey bees.
- Tare the balance with container.
- Place honey bee in container.
- Weigh honey bee.
Note that the weight of newly emerged bees is influenced by the meconium (faeces that is expelled in purging flights after emergence, Jackson and Hart, 2009). Adult weight is also influenced by the consumption of food, and standardized starvation of bees in an incubator corrects for this increase (see the BEEBOOK paper on maintaining adults in vitro in the laboratory, Williams et al., 2013).
- Record weight.
