The recent decades witnessed the collapse of honey bee colonies at a global level. The major drivers of this collapse include both individual and synergic pathogen actions, threatening the colonies’ survival. The need to define the epidemiological pattern of the pathogens that are involved has led to the establishment of monitoring programs in many countries, Italy included. In this framework, the health status of managed honey bees in the Emilia–Romagna region (northern Italy) was assessed, throughout the year 2021, on workers from 31 apiaries to investigate the presence of major known and emerging honey bee pathogens. The prevalence and abundance of DWV, KBV, ABPV, CBPV, <i>Nosema ceranae</i>, and trypanosomatids (<i>Lotmaria passim, Crithidia mellificae, Crithidia bombi</i>) were assessed by molecular methods. The most prevalent pathogen was DWV, followed by CBPV and <i>N. ceranae.</i> Trypanosomatids were not found in any of the samples. Pathogens had different peaks in abundance over the months, showing seasonal trends that were related to the dynamics of both bee colonies and <i>Varroa destructor</i> infestation. For some of the pathogens, a weak but significant correlation was observed between abundance and geographical longitude. The information obtained in this study increases our understanding of the epidemiological situation of bee colonies in Emilia–Romagna and helps us to implement better disease prevention and improved territorial management of honey bee health.

Here, we present the results of an online international survey concerning the adoption of good beekeeping practices and proper biosecurity measures for the management of varroosis in Apis mellifera. The survey was designed as a risk assessment tool by the Food and Agriculture Organization of the United Nations (FAO), the International Federation of Beekeepers&rsquo: Association (Apimondia), the Center for Analytics Research &amp: Education (CARE) at Appalachian State University, and Istituto Zooprofilattico Sperimentale Lazio e Toscana (IZSLT). The data collected investigated the beekeeping techniques, treatments, and training beekeepers adopt concerning the varroa mite. The idea was to validate a tool able to collect and compare, in the different areas of the world, the management measures adopted by beekeepers to face this major parasitic disease of honey bees. The survey was disseminated online for a period of 14 months (January 2019&ndash:March 2020) through the FAO website. A total of 861 responses were received, most of them from the Americas (20.9%) and Europe (74.7%). Concerning the control measures useful in combating varroa, the results showed an overall awareness of the usefulness of biosecurity measures in beekeeping (BMBs), which we compare across regions. The majority of the beekeepers (89.9% in the Americas and 82.8% in Europe) were interested in additional bee health training and, at the same time, were willing to connect themselves with veterinary experts specialized in bees. This is an indication that beekeepers recognize the importance of training and experts&rsquo: advice. This study revealed the efficacy of the survey adopted as a useful assessment tool that will be further disseminated, even in geographic regions heretofore not investigated, to provide useful information on the status of the beekeeping sector.
