Hundreds of bees flying today, its about 65 degrees. Maybe I have more bees in there than I thought.
Happy Thanksgiving to you and yours!!!

Yes... I also thank you and people like you that will meticulously measure and record data such as this.... it helps everyone make educated decisions about how to manage their own hives..... I know I can't do it, but just happy when someone can.
Cheers

Thanks for the compliments but I dont think I am going through this again. I plan on having 3 hives next year and it will be too much to "count". I will just monitor the mites. NO MORE COUNTING. I want to be a beekeeper, not a mitekeeper.

I wonder if the mite reduction has more to do with brood reduction/elimination than anything else. All my hives are on SBB's and I check them every month or so. My 24 hour averages went about such:
early spring.... 3
late spring.....10
early summer....20
late summer.....30
fall............15
late fall.......5

I don't use any chemical treatments at all. I do use russian bees and SBB's as I have mentioned, so my only explanation for the dropoff in mites is brood reduction. I've got about 100 hives and didn't lose any to mites (I did lose hives to robbing, queen loss, etc. however). I had several hives that got up over 100 mites/24 hrs, but even they eventually reduced there count to close to the others. I hope this will be sustainable over various conditions through many years, because I'm not going to ever use chemicals ($, time, quality concerns).

Here is an observation:

I have not been counting, but I have been checking for mite drops from the 5 hives I have at home (I have 3 more a few miles away that surprisingly have not shown almost ANY mite drops throughout the summer and fall; perhaps they are the only bees in the area and have no other to pick the mites from).

All of the 5 hives at home showed very few mite drops througout the summer (I only fogged with FGMO about once/week). However, 4 of the 5 started dropping more and more mites daily in September, but one showed very low counts even through all of October and part of November.
I treated the 4 with high counts with oxalic acid once per week 4-5 times, and the 5th only a couple initially and them stoppped since no mites were falling. Then a couple of weeks ago this 5th hive started dropping dozens to hundreds of mites per day. I treated this and the other hives again and now the numbers in the 4 initial ones are down to 0-4/day, and the 5th is still high but dropping.
What was different about the 5th hive is that the queen in that hive layed many eggs way past what the other queens did. Because the temperature has been low (and due to lack of time) I did not inspect the hive very often to see if the high mite drops coincided with the hatching of the latest batches of brood, but there was that major difference.

So, my hypothesis now (without any evidence to prove or disprove it) is this: the mite count that always shoot up so dramatically in the fall even after long summer periods with almost no mite drops may be due to a synchronization in the laying by the mites. If they all start synchronizing (and perhaps also multiplying the numbers of) their laying of eggs, then missing the hatching of one wave of mites when applying the oxalic acid treatment can allow the explosive proliferation of this creatures.
Alternatively, perhaps theu change their behavior and in the fall, instead of moving out of the cells as they probably do at other times, they stay INSIDE the cells for a larger fraction of the time. The oxalic acid (or other chemicals used to treat for mites) may not reach the deep ends of cells as effectively allowing more mites to survive and reproduce.
Has anybody with observation hives noticed such behavior in mites in the fall?

This phenomenon is what I've noticed every year since I started monitoring the mites. The mite counts will be fine into the fall when they quite suddenly explode.

My theory is that it is a combination of the mites doing their best to reproduce that late, the population that is carrying the mites is decreasing, and the bees are hauling back hitchhikers from crashing hives. But I honestly don't know how the numbers increase so rapidly.

Greetings newbee 101,

Have you seen many/any dead bees in front of hive? Bees without wings or wings that look like they have been "chewed off"?

My counts are simular (chart/graph looks the same), and I have been collecting 5-8 dead bees daily (guess they are young bees hatching from heavily infested cells).

Now your mite counts are low, but what/how much damage (if any) has been done.

Hope we dont experience "winter kill" w/ this one!

A month or so ago I was getting crippled bees ect... No dead or crippled bees now.(no brood)
How many bees do I have left? Thats the big question I wish I knew the answer to. I went in a couple of days ago to see what goo was dripping from the front of the hive. I put a patty in to feed them a bit and the bees generated enough heat to melt the patty , so hopefully theres enough to make it through the winter.
