Dr. Neumann hat es mir damals zwar erklärt, aber ich bekomme es nicht mehr zusammen: warum kommt es bei der Varroamilbe nicht zu einer Inzuchtdepression?

#Varroa mite detected in #SouthAustralia for first time!

The discovery was made in a #beehive at #Pooginook in the state's Riverland during routine surveillance by PIRSA inspectors.

The infested hive is believed to have originated in a consignment of hives from Queensland. #auspol #bees #apiarist

Die Ameisensäure hat voll eingeschlagen. Kampf gegen die Varroamilbe ist in vollem Gange. 💪 #varroamite #varroa

Just in case you think Australia’s biosecurity is robust.

Sonntag ist Milben-Zähltag

Ich führe wöchentlich Buch über den Milbenfall. Ziel ist es einen Überblick über die Belastung mit Varroa und Rückschlüsse auf Völker mit einer guten Varroatoleranz zu bekommen. Was sich wiederum bei mir auf Selektion und Zucht auswirkt.

Hier sieht man eine der Varroamilben auf dem Varroaschieber, wie dieser Einschub genannt wird, herumlaufen.

Der Schieber wird nach Auszählung sauber gemacht. Diese eine Milbe ist damit sicher aus dem Volk

Honey

Went and picked honey last week from my supplier, a bio security Officer for Varroa (Varroa development officer). The jar on the right is what I normally get, ‘cause honey. 🍯🐝

Not now. I can only get the middle and left size. Why?

The impact of #VarroaMite on local hives. The example he gave was from our OS SE Island neighbours where the number of hives went 2000 to 8. This is the future of bees in Victoria.

Interesting:

"Varroa mites originally evolved to parasitize Apis cerana, the honey bee species native to Asia, and only affected drones of that species. When Varroa mites infect worker brood in Asian bees, the larva dies and the Varroa mite can’t reproduce."

"As they adapted to the honey bees (Apis mellifera) common in Europe and North America, however, Varroa mites became able to parasitize drone, queen, or worker bees. However, there is a still a large preference for drone brood. Varroa mites are often 5–10 times more abundant in drone brood cells than worker or queen cells. Since drones take longer to mature into adults and the drone brood are bigger, the Varroa mites can produce more offspring in these cells. By removing excess drone brood, a beekeeper can eliminate a large portion of their Varroa mite population."

Last week, we had some warm days (15°C), perfect for checking the hives. Out of 10, one didn’t survive—likely due to varroa. Another was too small to make it through spring. A tough part of beekeeping, but nature moves on. #Beekeeping #SaveTheBees #Biodiversity #Varroa

I am ecstatic to learn that one of our beehives is still varroa-free, here in #brisbane, #australia. It's only a matter of time before they get here though. 🙁

I also harvested about 20kg of honey. The bees were very calm, though it was 30°C and 80% humidity. Sweat city. I'll check our other hive next week.

Vor 5 Wochen waren die #Bienen in der #MelliferaEinraumbeute stark vermilbt mit #Varroa. Wir haben die Bienen dann in der Beute links neu Waben bauen lassen unter täglicher Fütterung. Heute sieht das #Bienenvolk so aus: eine wunderschöne Halbkugel #Naturwabenbau.

Making a thing.

When you need a strainer of a particular size, find something created in OpenSCAD and change the dimensions. v2 was sized and spaced ok but it was too thin. v3 fixed the thinness and added some rings for support around the diameter. The rings were added in the slicer.

A bee strainer for checking for varroa mites that fits in a peanut butter jar.
