Caution. 



Prevent robbing. 



Clean up the bee yard. 



Do not feed honey unless boiled. 



Have a sample of brood examined if a colony dies, fails 

 to build up or dwindles. 



Treat colonies immediately upon determining that they 

 are diseased. 



Combs, supers, section boxes, etc., should not be trans- 

 ferred from hive to hive in an infected apiary. 



Melt up old combs ; burn the refuse. 



When handling infected material, and after treating a 

 diseased colony, as a precaution, disinfect the hands, tools, 

 etc., with a 5 per cent, solution of carbolic acid, or a solu- 

 tion of 1 part of corrosive sublimate (mercuric chloride) to 

 1,000 parts of water. 



In introducing queens, the candy in the mailing cage 

 should not be put into a healthy colony. It is safer to re- 

 move the queen to a sterile cage and introduce her, un- 

 accompanied by her escort of workers. 



In purchasing bees, the buyer should be certain that he is 

 getting stock free from disease. 



Beekeepers in the vicinity of greenhouses where bees are 

 used to fertilize cucumbers should insist that discarded hives 

 and combs are not thrown out, exposed to the access of 

 robbers. If of no value to the cucumber grower, such mate- 

 rial should be burned. 



Do not be mistaken in believing that the so-called ' ' bee 

 moth" or " wax moth" causes the loss of a colony of bees. 

 The destruction by this insect is usually secondary ; fre- 

 quently one of the brood diseases is primary, and the 

 ' ' moth " enters as a direct result of the depleted condition 

 of the colony. 



Other Diseases of Bees. 

 There are several other diseases or so-called diseases of 

 bees, among which may be mentioned chilled brood, over- 

 heated brood, starved brood, pickled brood, dysentery and 

 paralysis.
