Die Studie enthält wieder mal nicht die wichtigen Daten dei man benötigt:

Erk Österlund hat geschrieben:Positive details in the study

1. One of the beekeeper’s own apiaries was used and its colonies were used in the test.. Thus, no queen was introduced to other types of bees in another place. The resistant bees and their queens were tested in their normal environment.
2. The distance between the test and the control colonies were big, 60 km.


Details missing

1.The name of the beekeeper. He had earned a place among the authors.
2. The beekeeper has exchanged breeding material with another commercial beekeeper since 2004. This beekeeper has also not been treating his bees for many years.
3.The number of bee colonies forming the resistant colony population is not mentioned.
4.The cell size used by the beekeeper is 4.9 mm, ie small cellsize, for almost as many years as he did not treat against varroa.
5.The cell size of the control colonies is also not mentioned. Is it also 4.9 mm or larger?
6. It is not mentioned if there are other bees close to the test and control colonies. The test beekeeper has several apiaries. If any of them are near the test apiary, it would probably not affect the test. How many other type of bees could be found near the test and control apiaries (if any) is not mentioned and, if so, the distance to these bees. It is important for the reinvasion risk.
7.Nothing is mentioned of annual losses for the years backwards for the test and control colonies. It may be of secondary significance and these figures may also not have been secured. However, some kind of data about of the losses at the beginning of the adaptation of the test bees could have been interesting to take part of. But the article is inspiring anyhow.
8.There are also no tips for beekeepers inspired by their article to start developing their bees to become resistant. Of course, it is not a task of the test I understand, but some kind of comment about this has been positive since many beekeepers will certainly appreciate the article and be inspired by it. However, such advice I look forward to find in follow-up articles in bee magazines.


Das ist nicht Hans-Otto Johnsen
Aber die Bienen des besagten Tests waren von Terje Reinhertsen und der hielt diese auf kleinen Zellen, 4,9mm und dieser wiederum hat sein Brutmaterial mit Hans-Otto Johnsen ausgetauscht. Und Hans - Otto bekam vor ca 15 Jahren 100 Elgon Ableger und hörte damals zum behandeln auf, hatte etwas Probleme zu Beginn, was sich aber einpendelte.

Die Frage ist nun warum weder Hans - Otto noch Terje in dem Bericht erwähnt werden und auch nichts zu der Zellgröße geschrieben wird.
:verwirrt:
