Installed package on May 30TH.I have been feeding 1-1 SS with HBH,I did not treat the new package with Fumagilin-B at install.My question is should I go ahead and treat them now or wait untill fall.The package is 7 weeks in since I installed them in a 8 frame med. and foundation.Two weeks ago I added the 2nd. med. with foundation but swapped out 2 frames of brood from the bottom with 2 foundation from the new med. on top.

I never bother with Fumagilin at all. As long as bees have enough to eat, and are not overwhelmed by mites or pesticides, they will do ok. Especially if they winter in a relatively warm place like Georgia...

Thanks jquinn,I sould have researched it a little more.I thought it was just another thing I needed to nip in the bud before it became a problem.I never knew it was more of a regional problem and the milder winters here in the South that we have unless another stress issue causes it I should't have to worry about treating.:thumbsup:

I don't bother with Fumagilin any longer. I do watch for signs of problems coming out of winter after the bees are trapped inside during the cold, just in case I need to treat. I don't treat with anything unless I suspect there might be a problem, granted it sometimes might be too late. I just don't believe in treating with chemicals as a preventive measure when there is no problem. Keeping a colony strong is the best defense anyway. For example, making sure you have a good laying queen goes a long way to keep a colony heavily populated which in turn helps with avoiding illness.

When I first got started with beekeeping the instructors also told me to treat with this at that time etc... I think they were just giving the best advice they could to idiot proof the process. Rather than describing the effects, signs and causes of nosema they just taught use to treat for it.

No problem :) If you haven't checked out Randy Oliver's site, http://scientificbeekeeping.com/ I highly recommend it--his articles really helped a lot when I started beekeeping. I also really like Michael Bush's take on things over at http://www.bushfarms.com/bees.htm

The first problem with Fumigillan is that it causes birth defects in mammals... which explains why it is illegal to use in almost every place in the world except here...
The second problem is that it contributes to Nosema ceranae:

The third problem is that it disrupts the microbes that protect the bees from Nosema (which probably explains why it contributes to Nosema ceranae.
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033188
The fourth problem is that it's only really effective on Nosema apis (if at all since it makes them more susceptible at the same time it is killing it) and Nosema apis has been almost completely displaced by Nosema ceranae.

Recently went to a lecture on nosema. Seems Fumigillin, or any other given item, doesn't do much good. Keeping hives healthy overall helps a lot.

When I have tried it many hives ignored the syrup with the Fumigillin but readily sucked back syrup without it.

I have only used Fumagilin B twice. The first year I saw a small reduction in dysentery. The second year it didn't seem to make a difference and I had high losses. Many of the hives didn't even eat the syrup with the fumagilin in it. I have gone two years without it and my hives seemed to be doing just fine.
