Aethina tumida (small hive beetle, SHB) was first detected in September 2014 in Calabria region, southern Italy, and in a single apiary in Sicily in November 2014. In September 2015, SHB was again recorded in Calabria, and in 2016, only sentinel honey bee nucleus colonies were found to be infested. Its phylogenetic relationship and possible origin were investigated comparing the cox1 sequences with the corresponding region available in the GenBank database. The neighbour-joining method revealed that the first Italian specimen belonged to a group also containing an African specimen from Cameroon. The Italian specimens differ from the SHBs spread worldwide and are split into two different groups: group B1 includes the AfricCam3 sequence and the first SHB identified in Calabria; group B2 includes specimens from Calabria and the only one from Sicily which share identical cox1 sequences. SHB in Italy appears to have been introduced from Africa and includes independent or contemporary incursions in the two concerned regions. The most likely scenario is that SHB was introduced into Calabria followed by man-mediated migration to Sicily. © 2016, INRA, DIB and Springer-Verlag France.

The first detection of Aethina tumida Murray (the small hive beetle) in Italy occurred on 5 September 2014. Three nuclei containing honey bees (Apis mellifera) and located in a clementine (citrus) orchard near an important international harbour in the Calabria region (southern Italy) were heavily infested with adult and larval A. tumida. A. tumida infestation is a notifiable disease of honey bees in the European Union as well as an OIE listed disease. To prevent any A. tumida introduction, the importation of honey bees is regulated strictly in the European Union (Commission Regulation (EU) No. 206/2010). Early reaction measures adopted in Italy require that beekeepers must notify A. tumida discovery to the local veterinary services and cannot move their colonies. Furthermore, a protection area (20 km radius) and surveillance (100 km radius) zone should be established. The surveillance zone now includes the entire territory of Calabria region. Compulsory visits to all apiaries in the protection zone with the collection of the spatial information by means of a georeferentiation process (georeferentiation can be defined as the process to describe a location relative to the earth, in this context the process consists on the collection of the spatial coordinate of a point that represents the spatial location of the apiaries by means of a GPS device) and colony inspection according to 5% expected prevalence (95% CI) are applied. Destruction of infested apiaries is compulsory and the soil under the infested colonies must be ploughed and treated with pyrethroids. If apiaries in the protection zone are found to be negative, traps are placed. In the surveillance zone, veterinarians visit apiaries that are selected according to a risk analysis (migration in infested areas, honey bee or materials exchange) or randomly and colonies are inspected according to 2% expected prevalence (95% CI). Furthermore, in Italy as well in the rest of Europe, investigations are in progress by competent authorities to make an inventory of all bees and colonies moved from Calabria during 2014. Subsequent controls on colonies should be implemented. People from the honey bee network (beekeepers, veterinarians, beekeeping material producers and distributors) should be aware and informed of the hazard posed by A. tumida to honey bees. © IBRA 2014
