2.1. Objective of epidemiological studies on honey bee colony losses
The epidemiological study of honey bee colony losses aims to determine explanatory factors for, and to monitor the magnitude and the spatial distribution of honey bee colony losses at the operation, apiary or colony level. This enables the formulation of good advice on prevention and control of colony stressors. In this section, we propose standardized case definitions to facilitate various objectives as follows:
1. Reporting and classification of cases of honey bee colony losses by national and international honey bee experts.
2. Standardization of language for communication purposes.
3. Comparability of data across time and geographical areas.
