Epidemiological comments In May 2015, beetle specimens were sent to an expert in taxonomy of beetles at the University of São Paulo for taxonomic identification The result of the preliminary identification was communicated to the official veterinary service only in December 2015 and the species Aethina tumida never reported in the country was indicated. Then investigations to confirm the agent and to assess the extent of infestation began. Beetles samples were sent to another laboratory of Entomology, which confirmed the species Aethina tumida in February 2016. The investigation in the hives currently present in the initial local detection did not show the presence of the beetle. Epidemiological investigations are on-going within a 20 km radius of the location where the first infested hive was detected. In an apiary in a neighboring municipality, adults of a similar beetle were detected. They were sent for identification. The property is interdicted until confirmation and the radius of investigation was extended. Meetings with representatives of associations of beekeepers and industries related to the sector of beekeeping were carried out on the guidance regarding detection, notification and prevention /control measures of the spread of the agent.
