\u2713 Peoples with late honey room release
\u2713 Peoples who were restless or almost aggressive
\u2713 Peoples who have raved
\u2713 Peoples who only reached the average in honey yield
\u2713 Peoples who weakened slightly at the end of July
\u2713 Peoples who achieved an index of over 32 points in the VRI exam.<\/p>\n\n\n\n
In the last week of July 2019 I have the Varroaindex test with approx. 50 peoples carried out. For this purpose, these selection peoples were brought home by the outstandings, since here the daily mite counts were easier to carry out in time. 10 selection peoples were shortlisted.<\/p>\n\n\n\n

This is recognizable by injuries to the mites, usually severed legs. The ratio of these two components is my measured value Varroakiller factor. If the VKF is 95% or more, this means that most mites in daily mite waste were killed by the bees before demiling. This in turn contributes to an inhibited varroa reproduction in the 10-month observation period. This resistance property works all year round, even in winter, when there is no brood. The other known resistance factors only work with existing brood. e.g.: The opening of infested brood cells, or the infertility of some varroas, these factors I have already found in my first selection peoples in 1990 and described in my two books \u201cBeekeeping today\u201d (1990) and in the book \u201cVARROAESISTENT\u201d and documented with photos. Another important resistance factor is the low attractiveness of the brood for the reproduction for the mites. This property is recognizable in demiling, most mites fall off already in the first days. All resistance factors together result in inhibited varroa reproduction over the observation period of 10 months. But again, a low demitting number does not necessarily predict good varroare resistance, a low demilbing number also arises when the people have swarmed or an optimal demiling has been performed.<\/p>\n\n\n\n Summary:<\/strong><\/p>\n\n\n\n The actual demildication number divided by the \u00d8 daily mite waste before demilding gives the measured value Varroare resistance index (VRI). The higher the varroa resistance of a people, the lower the VR index. For example, my 5 breeding peoples show an average VRI of 20.45 points, which means a very good varroa resistance. A bee colony with a VRI reading of 100 or more has no natural varroa defense. The great advantage of this resistance calculation is also that the test peoples are not exposed to unnecessary exposure to the varroa mites.<\/p>","protected":false},"excerpt":{"rendered":" Varroaresistenz, die Messwerte meiner Zuchtv\u00f6lker f\u00fcr das Zuchtjahr 2020 Das Bienenjahr 2018 In diesem Zuchtjahr habe ich \u00fcber 100 Ableger gebildet.

The Varroare Resistance Test at the end of July 2019 \u2013 The results:<\/strong><\/p>\n\n\n\n![\"\"\/](\"http:\/\/temp.voralpenhonig.at\/wp-content\/uploads\/2026\/02\/image-2.png\")

The \u00d8 VRI index of all peoples of this group is \u00d8 23.8 points. In comparison, the \u00d8 2017 ethnic group had a \u00d8 VRI of 30.50 points. The lower the VRI index, the better the varroare resistance. This improved resistance by 6.7 points (23.8 in 2019 versus 30.50 in 2017) impacts the varroa mitigation number. Compared to the groups of 2017, the demilting number fell from \u00d8 1187 mites to \u00d8 719.2 mites. The daily mite waste before de-milling has also decreased from \u00d8 41.6 mites to \u00d8 29.50 mites.
The further selection<\/strong>
However, I would like to further select these 10 selection peoples on 5 peoples. On the table I have already ranked the 5 peoples with the best index values of 1-5. These peoples are my breeding peoples next year (2020). These 5 peoples I am subjecting to a \u00d8 calculation. The result of the \u00d8 reading of the breeding peoples is:
\u2713 \u00d8 VRI Index: 20.50 points
\u2713 \u00d8 Decay waste after 10 months: 516 mites
\u2713 \u00d8 daily mite waste before demilding 25.4 mites
<\/p>\n\n\n\n
The VRI compared to the overall group of 2019 has improved from \u00d8 23.80 points to \u00d8 20.50 points. This improved index is having an effect. The demiling number has decreased from \u00d8 719.2 mites to \u00d8 516 mites. \u00d8 daily mite waste before demitiling has also decreased from \u00d8 29.5 mites per day to 25.4 mites.
The VARROAINDEX<\/strong> is the ratio of the daily mite waste before demiling to the actual demiling number after demiling. With this index number, I can see even a slight improvement in varroa resistance. The comparison with the group of selection peoples of 2017 shows a very large breeding progress of the offspring. This year, in 2019, I formed about the same number of offshoots as in 2018. These will be selected as discussed in 2020.<\/p>\n\n\n\n![\"\"](\"https:\/\/temp.voralpenhonig.at\/wp-content\/uploads\/2026\/02\/image-3.png\")
