PRACTICAL QUEEN REARING 



the new lot of queens, had previously purchased a breeding 

 queen from the breeder from whom he had first contracted the 

 disease. It accordingly became necessary to requeen his apiaries 

 with new stock, a second time, to get rid of paralysis. 



Diseases of adult bees are, as yet, but little understood; 

 but it is quite probable that there are several different diseases, 

 all of which are known under the general name of paralysis. 

 It is very evident that this trouble, whatever its nature, is 

 widely disseminated by the sale of queens and bees in packages. 

 The trouble has long been prevalent in the south, especially 

 in Florida, but, of late, it is becoming common in many northern 

 localities. It has attracted special notice in Wisconsin and 

 Washington. In dry and warm seasons it is not serious, but in 

 cold and damp summers becomes a serious problem. 



Cases have been called to the writer's attention, where 

 all the bees introduced from a certain locality have died with
