English visitors: https://dodsbisyssla.com/insulated-and-condensated-hive/ Bina sitter still i sitt klot/kluster hela vintern och värmer bara upp området där de sitter och därför behövs ingen isolering. Bina sitter under maten och honungen håller därmed samma temperatur som utsidan varvid klustret rör sig sakta uppåt vartefter maten tar slut. Det här var vad jag länge trodde men detContinue reading “Isolerade kupor som får kondensera”

English summary: I have, for a while, considered to purchase temp sensors and now I took the step and sourced both temp and humidity sensors. My work on the bee guide is moving and now I think the main chapter describing winter in is finished. Nu tog jag steget och köpte ett antal temp ochContinue reading “Ännu ett steg in i nörderiet samt färdigt kapitel”

English summary: After the epiffany of the value of insulation in the hive I have come up with an easy fix by adding 50 mm of cellular plastic which increase the R value to about 15.Efter att ha insett hur viktigt det är med isolering har jag funderat hur man enklast kan förbättra klimatet förContinue reading “Enklaste sättet att förbättra klimatet för bina”

För den som är intresserad kör vi ett webinar på sö 31/11 där ämnet är isoleringens betydelse för en bra övervintring: Isolering eller ventilation – bästa sättet att invintra bin?den 30 november 202518:00 – 19:30 (WET) Möteslänk: Isolering eller ventilation – bästa sättet att invintra bin? | Microsoft Teams | Snabbmöte-anslutning

English summary: We started a small test in the autumn to compare top cover made by wood to a plastic one with the hypothesis that wood is more risky since the condensated water might be absorbed by the wood and later start to mould. Today we checked a couple of hives with plastic lid andContinue reading “Stoppat test och månadsvägning”

English summary: I have completed another chapter in my planned bee book, and its possible to download it under the menu “Bibok”. Its in Swedish but google can assist. För den som vill läsa och ge feedback finns nu kapitlet om “Våren” att ladda ner under fliken bibok.

English summary: Another subject where opinions varies is how many eggs a queen can lay per day and how long she can live. I did a review of the research and found that it seems that the maximum capacity of a queen is around 1,3 Mio eggs which gives a life span of 3-5 years.Continue reading “Hur många ägg kan en drottning lägga?”

It is surprising how often old knowledge seems to be forgotten and that the wheel needs to be invented over and over again. I stumbled over an old study from 1920 where the author tested hives with or without insulation and the clear result was that the bees survived in unisolated hives but the beesContinue reading “Gammal är äldst – 105 år gammal studie ger “ny” insikt.”

Englsi summary: We have been using Lactic acid (LA) as our “go to” treatment for many years since it is effective but still mild towards the bees with no negative effects reported. Regrettable, until now I haven’t found any study that explains how LA works and why it is not impacting the bees as well.Continue reading “5 nov 2025 – hur mjölksyra fungerar”

English summary: In the figure below we show the result of this years mite count and it seems that we have a decent number of colonies with some degree of resistance (green marked). Of totally 18 colonies (with nuc’s and swarms included) only 2 needed Formic acid and, as always, no oxalic treatment used. WeContinue reading “27 oktober – sammanställning av årets kvalsterräkning”
