16 DISEASES OF BEES 



A thorough study of the control methods employed in the case 

 of European foul brood must be made. In two cases in which swarms 

 from colonies affected with European foul brood were hived on 

 fresh foundation in clean hives the disease did not reappear. In 

 another case in which a swarm was hived on drawn comb the 

 disease soon broke out again. It is not improbable that the shaking 

 method will prove of value in eradicating European foul brood in 

 very obstinate cases of the disease which have failed to respond to 

 the usual requeening treatment.
