Disease Testing

Testing for disease in bees is now free in Ireland.

Varroa Calculator

The tool linked here, will help you calculate your Varroa Load after a mite count.

Suspected Bee Poisoning

If poisoning is suspected email beekeeping@agriculture.gov.ie.
This account is monitored by a number of people and someone will reply to you with the sample size needed to confirm suspected poisoning.

In the interim, try and put a minimum of 15 gm bees up to a full honey jar amount into the freezer. The sampling is free at the moment and DAFM will screen for the common chemicals. It is not always possible to identify the source of the poisoning due to the fact that bees have a large foraging range.

Sampling for Disease

Update: DAFM 2023 contact person Sinead Mulcahy

Update Mar 2020: ​As you are aware there was a recent competition to recruit for a specialist to work in the area of honeybee health in DAFM. I am pleased to say that the new recruit has started work in the Plant Health Laboratory here at DAFM in Backweston. The appointed person is Dr Mary Coffey.

This means that there will be some changes to the current honeybee disease diagnostic service that was funded by DAFM with analysis carried out by Dr Coffey in Teagasc. The disease diagnostic service will still continue but samples will now need to be submitted using a new form and directly to Dr Coffey in the Plant Health Laboratory at Backweston.

The new service will now also be named the DAFM honey bee health surveillance programme. The new service will be available on the website at the link below along with sampling guidelines https://www.agriculture.gov.ie/farmingsectors/beekeepinghoney/beehealth/

Any queries regarding the analysis can be directed to maryf.coffey@agriculture.gov.ie

Any general enquiries about the new DAFM honeybee diagnostic service can be sent to Rachel.wisdom@agriculture.gov.ie

We would appreciate it if you would communicate this information to all your members as samples sent to Teagasc in Oakpark will no longer be analysed. This service will still be free of charge.

Kind regards,
Rachel.

Sampling for Nosema & Acarine

Which bees should you sample?

You will need about 30 bees, this number of bees conveniently fits into a matchbox.
You want to try and sample the older bees. Nosema in the gut increases during an infected bee’s life, so the older bees are lightly to have higher spore counts. Bees under 8 days of age won’t have any spores, so sampling them could lead to “false negatives.”

To sample, block off the hive entrance causing the returning foragers to pile up.
Partially open your matchbox and with a sweeping movement collect the bees that have accumulated on the side of the hive.

Close the matchbox and put into the freezer. This will kill the bees.
The same sample will be used for diagnosis of acarine.

The bees can then be posted to Dr Mary Coffey at the above address.

Sending Comb for Diagnosis

  • Locate the queen and make sure she is safe.
  • ​Select a sample of comb from the centre of the brood nest.
  • Shake to remove the bees and remove the frame from the apiary.
  • Cut out a piece of diseased looking comb 15 cm*15 cm, without honey and nectar, and wrap that in newspaper.

​That sample together with the above form can then be posted to Dr Mary Coffey for analysis of the brood diseases AFB, EFB, chalkbrood and parasitic mite syndrome.
