TKEVTMENT OF BEE DISEVSES. 





tlie base of the cell (fig. 5, /, h), or a shapeless nia«s on the lower side 

 wall if the larva did not retain its normal position (fig. 5, ?t, o). 

 Very few scales are black. The ^-cales are not adhehi\ e, but are easily 

 remoA ed, and the bees carry out a great many in their efforts to clean 

 house. 



Decaying larvae which have died of this disease are usually not 

 ropy as in American foul brood, but a slight ropiness is sometimes 

 observed. There is u-^^ually little odor in Euroj^ean foul brood, but 

 sometimes a sour odor is present, \Ahich reminds one of yeast fer- 

 mentation. This di^ea^^e attacks drone and queen lar\ m ^ almost as 

 quickly as those of the ^^ orkers.

European foul brood is more destructive during the spring and 

 early summer than at other times, often entirely disappearing during 

 late summer and autumn, or during a heavy honey flow. Italian bees 

 seem to be better able to resist the ravages of this disease than any 

 other race. The disease at times spreads with startling rapidity and 

 5s most destructive. "Wliere it is prevalent a considerably larger per- 

 centage of colonies is affected than is usual for American foul brood. 

 This disease is very variable in its symptoms and other manifesta- 

 tions and is often a puzzle to the beekeeper. 



^The tendency of this disease to attack queen larvie is a serious drawback m tr^at 



ment Frequently the bees of a diseased colony attempt to supersede their queen, but 



the larvai in the queen cells often die, leaving the colony hopelessly queenless. The 

 colony is thus depleted very rapidly
