Glistening honey in the cells -- almost harvest time! Bees remove water and chemically convert sucrose into simple sugars (fructose and glucose) to make honey. When the honey is 'ripe' (water content is <18%), the workers seal each cell with a cap. Well, if we can breed bees that do not cap their honey. it would make extraction much easier. I am ordering an uncapper today (May 28, 2003), which will cost $1,200 (the cheapest that I can afford!). July 2002.
 
 
 
extraction
 
 
Sealed honey has to be uncapped. This photo shows uncapping using an electrically heated knive. This is ok if you have less than 40 hives. Your hands will become very sore after a few hours.
 
 
 
An electrically heated knife is used to remove the honey cappings here. Bees cap honey when the honey is "mature" (moisture < 18%). The cappings must be removed before honey can be spun out by centrifugal force.۰
 
A electrically powered, radial extractor. Frames are putinto the extractor radially and honey flies out from both sides of the frame.

Disease & Pests
 
A healthy colony, with a young queen, should produce brood like this. While the brood is healthy. There are something usual about the pattern of capping. Have you seen anything different? Next photo explains why
 
Well, this capping is not 'normal' or 'usual'. Notice the rosette pattern? one normal looking brood cell was surrounded by six sunken cells. Normal brood should all look like the center cell. After seeing this in my observation colony, I was betting with my lab members that there were probably no brood in these sunken cells. I was wrong! there were normal worker pupae in all cells. Genetic? when the colony swarmed, I harvested it and the same queen produced similar pattern in the new colony! I should have saved a frame in the freezer and could have published another paper...Prof. Randall Hepburn (South Africa) has written a book on wax of bees and showed many strange patterns but he has not seen this type either. He did see rosette patterns before, but usually the center cell is a 'false' cell (no larva). Here all cells have larvae. MSU observation hive, May 3, 2000.
Note, I have discovered (on June 3rd, 2003, three years and one month later...) another queen is doing this again, in the same observation hive! We will try to 'study' what causes these wierd cappings to occur.-- Zachary Huang
 

 

Brood of Apis mellifera uncapped by workers. Pupae seem to develop normally within these uncapped cells. The significance of this is not clear. Some think bees maybe uncapping the cells when they detect varroa mites there. It is true also in Apis cerana this phenomenon is more common, where varroa is not a problem. MSU apiary.

A frame of brood that is not so healthy. The white stuff in cells are chalkbrood mummies. This colony is probably infected with chalkbrood, possibly also brood disease (AFB or EFB), and perhaps also varroa mites. When varroa mite infection is severe, it often causes frames like this, which is called bee PMS (parasitic mite syndrome). Photo by Prof. M.V. Smith, University of Guelph
