Varroa mite issue

Recommended Posts

Hi. I removed bayvarol from my hives 2 weeks ago and now when im doing my mite wash counts im finding varroa numbers from 6 to 100 on bee counts of 300.

 

I figure this is resistance to bayvarol or a faulty batch.

 

Im gonna put Apistan in all my hives.

 

Based in Whangarei, but no issues like this on my Ngawha hives.

 

Anybody got any comments to make on this.

 

thanks

Bayvarol and Apistan are the same chemical product.

You would be better to use Apivar or Apitraz.  This is a different chemical group

Did you leave the strips in the sun?

No, they were ordered and put in a cool room for a few days and then they went in the hives

You need to count the Mites as the strips are removed and or look through the Brood at that time.
If the strips are in and the brood is full of mites then there is a problem.
However a Hive can be full of Mites with the strips in but the Mites could be pouring in with returning robber Bees.
If a Hive is full of Mites yet the Brood is clean then thats another re invasion clue

Also.

Not telling you how to suck eggs.

But, How many strips per brood box did you use.

What is the time period the strips were in.

Did you move the strips during treatment.

 

Sorry.  Just trying to get the picture.

Yes so maybe a re invasion issue as the brood looks good and there is no signs of DWV or PMS.

I guess i still have to treat again otherwise im gonna have some issues soon?

I used 1 strip per 2 frames of brood. They were in for 6+ weeks and were moved with the brood.

The more i think about it and talk about it, i figure this is re-invasion. We had high mite numbers when we treated and if we still have high numbers number we would for sure have seen the effect on the brood and bees, yet the hives look healthy. So maybe its not resistance. I will do resistance test to find out.

what part of Whangarei?

it would not surprise me at all if there was abandoned hives around Whangarei. with current honey prices etc there is likely to be those who have just walked away from it.

you will get loads of mites from them.

A count of 100 can’t be sustainable for long surely?

Has anyone had counts like that for long or any idea how long a hive can tolerate that level?

assuming that those 100 mites (per 300 bees) indeed come from reinvasion you MUST make sure they dont reach the brood (especially around this time of the year where the longer living winter bees are reared)

 

so definately treat again (the idea to use another substance sounds like a good idea just in case)

So how many strips did you use??  The correct dosage is 4 strips per box of bees eg 8 strips for a double brood box hive.

I'd go as far as saying 8 strips for two boxes of bees.

 

The brood thing is misleading and encourages people to undertreat.

 

That said, I've gone away from such products as my results were poor even with full treatment

Mite counts depend on where you are.
For example I got a 85/260 count last week and treated that day.
That hive will have a 50/50 chance of survival because up here in west Taupo there isnt much time left for the Queen to organised a viable winter hive.

In coastal areas there's  probably plenty of time left for hives to recover from high Mite loads.

There are lots of Beeks still out there that are not using Alc washers so next season Ill be including those easy wash shakers in many of my Staple orders.,
Get ready Ecrotek

Here’s a sugar shake we did last week. I gave up counting at 160. In s yard of 40 it was the only dud hive. First hive on firstpallet in the half moon yard.... so i’m picking it got all the drift. 

We put more O/A staples in, but experience tells We’ll make it up again in the spring.

I'd probably save yourself a bit of cash and go around and give the bees a squirt of O/A and syrup ..... then go talk to Dr Phil.

Any chance you could do a video of alc wash and sugar shake for varroa?

Here is Alcohol wash.

 

And this one is CO2 wash.

Here is a video I made today about Mite washing
Not in Trev's league but gets my basics across, I hope

https://youtu.be/HEp83ru6zO4

 

To clarify the counting bit
Once the shake is done the mites are in the clear lower bowl
I carefully pour the meths back into the drum ensuring the mites dont flow back into the drum also
They tend to be heavy so its unlikely they do this.
Then with just a few MLs of meths left in the bowl I count the mites by looking down into the Bowl rather than the alternative system of holding the bowl up and counting mites through the clear plastic.
Often there is a lot of debris in the bowl and looking down into the bowl is far more accurate
