Go easy monitoring your mites: New CO2 option for Varroa EasyCheck!

The decades-long fight of beekeepers against one of the biggest enemies of the apicultural industry still remains a big issue. The varroa mite, Varroa destructor, since its migration from the Asian honey bee (Apis cerana) onto the Western honey bee (Apis mellifera) in the 1960s and 1970s, is widely regarded as the most dangerous parasites of honeybee colonies.

Varroa mite populations in honeybee colonies build up in the honey bee brood every season and can never be completely eliminated in honey bee populations where they are present. Inevitably, beekeepers are faced with no choice, but to fight the mite constantly. This calls for strategic decisions and requires some planning ahead. Putting this into perspective, monitoring varroa has become a crucial everyday component of beekeeping today.

Monitoring allows beekeepers to avoid critical levels of varroa mite infestation and serves as a guide in effectively timing miticide applications.

With our focus on apiculture, Veto-pharma made available the first ready-to-use “3 in 1” monitoring tool: Varroa EasyCheck. Alcohol wash, powdered sugar roll and CO2 injection are the three monitoring methods using the same tool – Varroa EasyCheck. Véto-pharma is pleased to inform you it has the injector and cartridge for the CO2 injection in stock now.

CO2 injection is a monitoring method that can be as effective as alcohol wash, but it leaves your sample of bees alive. The process is super clean and easy. This procedure also saves time as it has proven to be the fastest of all 3 methods.

Unlike the sugar roll method, which can get messy (especially during honey flows, when bees can regurgitate the nectar, or during humid weather) and which may require more time, the CO2 injection method is quick (30 secs) and highly effective, comparatively.

The CO2 injection method for varroa monitoring is easy as pie: Collect a sample of 200 or 300 bees with the white basket, preferably from a frame of capped brood (make sure the queen is not in the sample).

  • Place the yellow lid on top. Create a small opening between the yellow lid and the transparent container and inject the CO2 through the holes of the white basket for 5 seconds, until the bees stop flying. Do not inject directly toward the bees. Then, quickly close the lid. Let the Varroa EasyCheck sit for about 10 seconds, until the bees are anesthetised.
  • Turn the Varroa EasyCheck upside-down and gently shake the sample for 15 seconds, so you do not hurt the bees. Varroa mites will be dislodged from bees and fall through the holes of the basket.
  • Open the yellow lid and count the mites inside. Calculate infestation rate per 100 bees, as for alcohol wash. Depending on if you took 200 or 300 bees divide the number of counted mites by 2 or 3 to get your infestation rate (in %). To interpret the results, please consult our Varroa Guide and/or your local thresholds.
  • Put the bees back in the hive where they will recover. Dispose of the fallen varroa mites, as most will still be alive.

Grab your tools (Varroa EasyCheck, injector, and cartridge), as we keep at it to defeat the mite and keep our bees safe.

Ask your retailer for your Varroa EasyCheck, CO2 Injector, and cartridges. It is all about varroa mites monitoring in easy-peasy mode.
