The National Bee Unit is carrying out enhanced monitoring and awareness raising together with local beekeepers after a single insect, confirmed to be Vespa velutina was killed at a sentinel apiary, reported by a beekeeper.Laboratory analysis has shown that the Asian hornet was a female but as it was dried out and damaged it couldn’t be ascertained if it was a queen or worker. Additionally it is highly likely to be from the European population rather than a new introduction from Asia and is highly unlikely to be the offspring of either of last year’s nests in the UK.Further information regarding the yellow legged Asian hornet can be found on Defra's Asian Hornet sightings page and on BeeBase’s Asian hornet page. Please direct all media enquiries to the Defra Press Office: 0330 0416560We continue to ask beekeepers to remain vigilant, record monitoring trap locations on BeeBase (guidance here) and report suspect sightings here.

During the 2021 season, two Asian hornet nests were located and successfully destroyed by NBU inspectors and APHA colleagues, following sightings reported via the Asian Hornet Watch app.The nest found in Ascot, and destroyed on 11th October, was 35 cm in diameter and contained six combs. Results from genetic analyses suggest that all Asian hornets collected in the surrounding area were likely to have come from this nest, and that the nest hadn’t reached the stage of producing adult sexual stages.The nest found in Portsmouth, and destroyed on 31st October, was 31cm in diameter and contained 4 combs. Results from genetic analyses suggest that all Asian hornets collected in the surrounding area were likely to have come from this nest. The nest had reached the stage of producing sexual stages but was highly inbred and a large proportion of the offspring were triploid.The queen and drones for both the Ascot and Portsmouth nest were highly unlikely to be direct offspring of the Gosport nest from 2020.Further information regarding Asian hornet can be found on Defra’s Asian hornet sightings page and on our BeeBase Asian hornet page.

Roedd yn 35 cm mewn diamedr ac yn cynnwys chwe adran i atgenhedlu. Mae canlyniad y dadansoddiadau genetig yn awgrymu bod yr holl gacwn Asiaidd a gasglwyd yn yr ardal gyfagos yn debygol o fod wedi dod o'r nyth hwn, ac nad oedd y nyth wedi cyrraedd y cam lle y caiff ffurfiau rhywiol llawn dwf eu cynhyrchu.Roedd y nyth a ganfuwyd yn Portsmouth, a'i ddinistrio ar 31 Hydref, yn 31cm mewn diamedr ac yn cynnwys 4 adran i atgenhedlu. Mae canlyniad y dadansoddiadau genetig yn awgrymu bod yr holl gacwn Asiaidd a gasglwyd yn yr ardal gyfagos yn debygol o fod wedi dod o'r nyth hwn. Roedd y nyth wedi cyrraedd y cam lle y caiff ffurfiau rhywiol llawn dwf eu cynhyrchu ond roedd wedi mewnfridio i raddau helaeth ac roedd cyfran fawr o’r epil yn driploid.Roedd y frenhines a'r dronau ar gyfer nyth Ascot a Portsmouth yn annhebygol iawn o fod yn uniongyrchol o’r nyth darganfyddwyd yn Gosport yn ystod 2020.Mae rhagor o wybodaeth am y gacynen Asiaidd ar gael ar dudalen golygfeydd cyrn Asiaidd Defra ac ar ein tudalen cyrn Asiaidd BeeBase.

Join regional bee inspectors John Geden and Maggie Gill and seasonal bee inspector Eleanor Burgess to find out about the common causes of colony losses over the winter and what can be done to prevent them. A hive autopsy will look at the signs and symptoms of starvation, varroosis, failing queens and other issues your overwintering bees can experience. Tuesday 15th March from 7:30pm – 9:00pm via Teams -  Register here Questions and photos can be submitted in advance to beekeepers@apha.gov.uk
