I came into the teaching room right at the beginning of a lecture on Oxalsäure. What exactly Oxalsäure is is not entirely clear to me (Leo says "oxalic acid" but that doesn't help at all), but that wasn't too important since I'm not sure what half the things we use in Bienenkunde are called in English anyway. It's kind of better that way. In any case, der Bienenmeister explained to us that we would be mixing distilled water, sugar, and Oxalsäure to make a thicker-than-water, highly poisonous concoction that we would then give to the bees. Apparently, the water dissolves both the sugar and acid crystals (this doesn't sound good), so that when the water evaporates, the bees eat and store the resulting crystals. The Oxalsäure is apparently not poisonous to the bees, but it is to the Varroa (a red-copper mite no bigger than an asterisk), which can kill off a hive during the winter if they're not treated. The varroa get into the cells with the larva and kill them before they can hatch. We had to treat for them now because the bees are not currently laying new young, so the mites won't be able to survive.
However, what this means is opening up the hive. It was warmer today than it has been recently, but the snow is still thick on the ground, and it was cold for even us. Imagine for a second...
It's comfortable in the warm, humming darkness inside the hive. The workers take turns beating their wings to generate heat, swarming in a clump around the all-important queen. The dark, furry mass migrates slowly around the hive, working their way gradually through the precious stores of food they've industriously stored during the summer. Inside the styrofoam boxes, they are safe and warm, content to stubbornly wait out the chilly winter outside.
Sorry, meine liebe Bienchen. |
If you feel just a bit sad and horrified, that's how I felt today. We cracked open every hive to douse the confused bees with our concoction, which had to be dripped right on them to be effective. They didn't like it much, and I don't blame them at all.
As you may imagine, the first hive was the worst. The hives are built of several levels, in most cases three or four: a bottom level full of combs (Waben) that also has the hive's only entrance and exit to the outside; a second level (Zarge), completely open to the first, also full of combs; and sometimes also an extra level that earlier contained the sugary feed (Futter) that the beekeepers give them to replace their stolen honey; and last, the styrofoam roof (Decke). At the first hive, Manfried (one of the other beekeepers) didn't realize that the bees would be clinging to the bottom of the second level, and instead of just tipping it, he lifted the whole thing off and swung it over the snow. The bees were scattered, dropping dazed and twitching in the snow, and the shouting began. The Zarge was replaced, and we rescued as many bees as we could from the snow with a dustpan and a bird's wing, but the whiteness was still pocked by little black specks. Then the Bienenmeister doused them with the chemical and we moved on. I felt a little shaken. For heaven's sake, they're bees--but it's still heartbreaking to see them fighting to crawl out of the deathly cold, waving their legs and fluttering their wings, freezing to death, and know there's no way to help. I took to killing the ones that lay helpless in the snow. I don't know if they felt pain as the winter stole their tiny whiff of life away, but I tried to make it fast.
We went on to the next hive, then the next. Some were alive and abuzz with anger when we let the cold in; some sent out kamikaze pilots that flew at our faces, and one even stung Rolf; some were tiny groups, huddled determinedly around their queen and meekly accepting their chemical baptism; and two of the hives were ghost towns, all of the bees dead, frozen or flown or killed by varroa. Only once more did one of the beekeepers make mistake and spill the bees into the snow, but it wasn't so many as the first time. My job was mostly to follow and watch, or help clean the snow off the top of the hives to open them, but a few times I got to take the bird wing and gently sweep the staggering bees back into the hive before it closed again, crushing them or stranding them to die.
Like I said, this was more than a bit heartbreaking. It seemed cruel, too, to disrupt their warm seclusion, even though I know that the varroa, untreated, can destroy the hive. I picked one fallen bee out of the snow and it crawled on my finger, its tiny feet gripping my skin, its feelers wavering feebly. I tried to flick it back into its hive; I don't know if it made it or not. I hope so. Today's lesson made me look forward all the more to springtime--and swarming season...
