The Department of Agriculture, Food and the Marine in consultation with the Department of Agriculture, Environment and Rural Affairs, Northern Ireland initiated a Small Hive Beetle (Aethina tumida), Tropilaelaps Mite and Asian Hornet Sentinel Apiary Monitoring Programme on an all-island basis in 2015. The aim of the Sentinel Apiary Programme is to ensure the early detection of three exotic pests, Small Hive beetle (SHB), Tropilaelaps spp. and the Asian Hornet. To date, Small Hive beetle (SHB)and Tropilaelaps spp have not been reported in Ireland, but their potential arrival remains a serious threat. The first discovery in Ireland of a live specimen of Asian Hornet occurred on the 25th of April 2021. There is no evidence that the Asian Hornet is established in Ireland at this time, however this discovery reinforces the importance of the Sentinel Apiary Programme. The Small Hive Beetle (Aethina tumida) is an invasive species originating from Africa. It is well established in the USA and Australia where it has proven to be a serious pest of honey bee colonies. In September 2014, the SHB was confirmed in Europe in southwest Italy and the risk of spread into other European countries is now considerably higher. Tropilaelaps spp. though not reported in Europe to date, remains an economically important pest throughout Asia and has the potential to spread into temperate regions. Under Irish and EU legislation these two pests are listed as notifiable diseases. DAFM would like to thank beekeepers for facilitating this programme.
