We have attempted to identify the factors that contribute to bee mortality by monitoring. The main result of this is that we now know how high bee mortality is, and the differences are between regions and locations. Despite the detailed questionnaires there are still some shortcomings in the monitoring. These are mentioned in Chapter 20 of Honey Bee Colony Health - Challenges and Sustainable Solutions.

• The monitoring focuses strongly on determining the mortality level. The measures bee keepers take to prevent mortality are not taken into account.
• The monitoring only measures mortality in the winter period. Mortality in the period from July to October, or other periods in the season, is often forgotten.
• The monitoring does not consider seasonal events, such as the weather conditions and giving winterfeed.
• The monitoring does not consider issues related to the development of bee colonies, such as their strength.
• The monitoring omits to ask certain questions due to lack of understanding of the causes. If people do not know what they are looking for, then it is not possible to ask the right questions.
• The monitoring does not take soil composition into account. Regional differences do not mean much unless there are clear indications. The local differences may be just as large.
• The monitoring of CCD is very inaccurate. This is because it is difficult for the average bee keeper to distinguish CCD from other phenomena that cause bee mortality.
• Monitoring viruses, as takes place in the USA only provides information about this part. It is also based on a virus diffusion model and does not take account of the manner in which the virus is manifested.
