I've never heard that one before. Where did you get that information? If that's true, why does the brood comb turn dark black, but the super comb stay light?The nurse bees cover organic matter with propolis and strengthen the comb with propolis.
This one is correct. They varnish the hive and combs with propolis. It isn't dirty. Bees may be many things but they aren't poor housekeepers. Everything is cleaned, polished, and sealed with propolis which has antiseptic properties. It is one method of combating disease. Like everything in life, it is not perfect nor foolproof. Honey bees still get sick. But they are healthier than bumble bees, whose living habits are a little more laxThe nurse bees cover organic matter with propolis and strengthen the comb with propolis.
Where did you get the study from?In a study of Acaricides in Honey, Beeswax and Propolis, Swiss Bee Research Center,
The Fluvalinate residue level in the honey combs of the same colony was on the average 5 times lower than in the brood combs.
The Folbex residue level in the honey combs of the same colony was on the average 12 times lower than in the brood combs.
The Perizin residue level in the honey combs of the same colony was on the average 10 times lower than in the brood combs.
So you think they are both made of the same material or dirty from traffic. On upper entrance hives, are the honey comb lighter because they track in snow?
I mean no offense when I say this, but I'll always stick with what an individual with a PhD in Entomology has told me to my face over what I read on the internet.This one is correct. They varnish the hive and combs with propolis. It isn't dirty.
Actually, I know Dave Tarpy and have met and talked with him lots of times. I would definitely go with what he says in most cases. But the world is big enough for differing opinions. I am sure that some of the staining is from the fecal material, some from the cocoons, some from stuff dragged in, but bees obviously paint everything in the hive with propolis so without doing a highly sensitive analysis we can hardly be certain of the proportions of eachI mean no offense when I say this, but I'll always stick with what an individual with a PhD in Entomology has told me to my face over what I read on the internet.
Yes, well, working as I do in the scientific profession, I assure you that scientists argue as much or more than anyone. They do little else than argue about scientific research. Any work that doesn't hold up to close scrutiny is not worth very much in the real world.Hard to argue with scientific research.
I was in no way attempting to claim the internet is an inferior way of communicating. Just that it's easy for everyone to put an opinion forth without checking it, verifying it, and assuring that it's correct (not the case here, just generally speaking).Oh, by the way, the fact that we are communicating "on the internet" does not mean we are communicating in some inferior way. Communicating via printed words has gone on for centuries, and this is not different from that, except that it is immediate. Back in the 1800s there were weekly bee journals published and people carried on back and forth conversations such as this one. I'm only sorry that Dave isn't in on this one. By the way, he never dismissed my opinions because I don't have a PhD, ask him.
