The main conclusion was that there was no universal factor explaining the decline of honeybees, in all the research provided. Despite this fact, as mentioned before, a large number of factors were involved (from pathogens to weather conditions, etc.). Which makes the possible extinction of honey bees not necessarily typical, but rather a bit confusing. However, on a specific aspect of the subject, in terms of bee colonies, the author believes that if "unusual colony losses" were to be explained in the future, research should be directed towards other measures such as : “the molecular pathology of bees”. focusing on the host (vector)-pathogen" (Verlang-Springer 2010). As not all colonies are explainable despite what the author and other researchers know or knew at some point
