7.3.3. Measuring protein consumption by caged adult workers in the laboratory

Consumption can be measured by weighing remaining food, and similar to carbohydrates, should be adjusted to calculate amount consumed per honey bee per 24 hours as detailed in section 7.2.3. It may also be appropriate to calculate quantity of protein consumed, rather than total mass of food stuff providing the protein. This can be determined when the proportion of protein in the food stuff is known. Consult section 7.7 to correct for mass of food stuff lost through evaporation.
