If only treating with Apistan once a tear which is better, to treat in the spring or fall? I have only treated so far in the fall but then again my lone hive is only going into their second year. I would think that tne fall would seem more productive because the treatment would kill off most of the mites in the fall leaving the overwintered hive more mite free and possibly more resistant. All newborn bees would be in theory mostly mite free in the spring , or not hmmm tell me? p.s what other more natural treatments are people using FGMO etc and how can these be obtained? I rarely see these on beekeeping sites. pharmacy? chem supply?
Here's one POV.
I think fall is best because it's the same mites you will be killing in the spring, since no brood is reared in the winter really, so why not kill them before they suck the life out of your bees all winter?
Either way will work about as well.
Personally I don't use Apistan at all anymore since it failed completely to kill my mites last time I used it. I'm doing FMGO, small cell, and oxalic acid.
Treatment of any kind, should always be based on NEED.
Do you need to treat this spring? Have you been monitoring your hive's mite load? How heavily infested is the hive, NOW?
METHODS of MONITORING include:
1) Sticky-board Test (w/SSB or Screen Insert)
2) Hive Debris
3) Frame Inspection
4) Brood Inspection
5) Powder Sugar-Shake
6) Ether Roll
7) Bee Wash
CULTURAL CONTROL METHODS include:
1) Restricting Queen - Breaks brood cycle, allowing bees to clean out diseased or damaged brood.
2) Drone Brood Removal
3) Small Cell Bees
PHYSICAL / MECHANICAL CONTROL:
1) Screened Bottom Board (or Beltsville Insert)
2) Dusting w/ Sugar or Flour
3) Scraping off mites w/ pollen trap
1) Genetic bees
2) Hygienic Behavior
3) Natural Resistance Selection

I can find the following on these:
A. Hirsutella http://www.nal.usda.gov/ttic/tektran...000136200.html
M. anisopliae http://esa.confex.com/esa/2002/techp...paper_7285.htm
B. Metarhizium ? is this really Metarhizium anisopliae?
Metarhizium anisopliae http://esa.confex.com/esa/2002/techp...paper_7285.htm
But where do you get any of them? I found nothing on bio-blast. Do you have a link or other info on it?
>. . I. Tobacco Smoke
I've seen some research on this and it was not very effective until the dosage was high enough to harm the bees. I have tried it and actually find that Tobacco smoke is a very effective calming agent in small amounts, but if you smoke them heavily it will cause the bees to pass out on the bottom board in a pile.
Yes, fall treatment is fine, but it means you need to treat at least one brood cycle before the bees start to cluster. You need to prevent the bees from entering the cell nad damaging the workers, the very workers that winter the colony over. It is not the mite that kills the colony over winter, it is the damage the mite does to the wintering bee that kill sthe hive over winter. My flow takes me well into fall, so I dont take my supers off intime to fall treat. If I had to I would, but spring treatmetn makes most sence to my operation.
I hate mites

As there is no EPA, FDA, or WTO OIE-SPS approval, there
are no production quantities yet being made, nor is it
yet available for sale.
Fischer Alchemy has made formal application for, and has
been working with the USDA for the last few months on a
technology license for the USDA-patented innovation (using
Metarhizium anisopliae to combat varroa). We hope to bring
this product to market under a USDA license much sooner than
has been the usual case with bee products that require EPA
and/or FDA approval, and I have my legal beagle doing the
paperwork to create a non-profit limited partnership
("Fungi Fun Guys, LLC") to produce and distribute a packaged
product utilizing Metarhizium in cooperation with some other
beekeeping houses with names that are familiar to all.
We expect to sell this stuff at cost. If we make any profits
by mistake, we will give the money to the EAS bee research
fund, as we do with Bee-Quick.
We hope that the bee supply dealers will share our strategy of
"a rising tide raises all boats", and realize that not making
a profit on a mission-critical "must have" item like effective
and food-grade varroa control will generate more revenue, and
hence, more profits in sales on the other items that they sell.
> I found nothing on bio-blast.
The company went bust, as "bio-control" companies have a
regular habit of doing. They were EPA-approved for only
cockroaches and/or termites.
Metarhizium is very impressive. I like it so much, I am
spending lots of money to "productize" it. But don't hold
your breath, as there is a big difference between a promising
research project, and a viable commercial product. I have
no idea what gremlins might pop up.
There are rumors of others wanting to market Metarhizium as
a varroa control. If they show us that they will do it right,
and at a reasonable price, we may hand them our license on a
silver platter to satisfy the usual "exclusive" that every
for-profit gang of capitalists thinks they need.
