Deformed Wing Virus (DWV) and its spread around the globe is the focus of a recent publication by Professor Robert Paxton and colleagues from the Martin Luther University of Halle-Wittenberg in Germany.
Monitoring for varroa: determining the level of infestation, and using the results to aid in control
The effective recognized monitoring methods, alcohol washes and powdered sugar rolls, utilize a sample of approximately one-half cup of honey bees by volume. The purpose of both of these methods is to separate the mites from the bees in the sample, enabling the tester to count them and estimate the infestation rate in the colony.
Varroa EasyCheck was developed by Véto-pharma in 2016 to provide an accurate estimation of the mite infestation levels in a hive with the alcohol wash method. Recent investigations in our apiary showed that the Varroa EasyCheck can be used equally with the sugar roll and CO2 injection methods as well.
Varroa monitoring before the end of summer treatment is probably the most overlooked task performed by a beekeeper. Knowing pre-treatment mite loads will provide you with information as to what to expect from your mite treatment.
Varroa infestations may be very different from one beehive to another and from one year to the next. A varroa control strategy must be devised on a case-by-case basis and deployed right from the beginning of the season. Click on the article to learn more about it.
Varroa mites plague nearly all honeybee colonies. Regular monitoring is key so as to know when to treat and how efficient has been your treatment. To help beekeepers check their hives more easily and accurately, Véto-pharma introduced “Varroa EasyCheck” 3 years ago.
According to a survey conducted each year in Eastern France, the later the treatment is applied, the higher the winter losses. Study conducted in 2020 on more than 29,000 hives.
2- Maisonnasse et al, 2014 – Study carried out by INRA (France) between 2009 and 2012 on 552 hives. Average of 5kg [11lbs] (up to 13kg, or 28lbs, per year) on a lavender honeyflow.
