circumstances it may seriously weaken the affected colony, 

 especially if breeding be at a standstill {e.g., during mid- 

 winter), predispose to the loss of the honey harvest and 

 may prepare the way to an attack of Acarine Disease, 

 resulting finally in the complete extinction of the colony. 



TREATMENT. 



Preventive. — Aim always at keeping strong stocks, 

 headed by young virile queens and follow rational methods 

 of management. 



In conducting .manipulations in the apiary, and 

 especially when dealing with infected hives, always keep 

 your hands moist with dilute Izal solution (1-400). 



Empty hives should be washed inside and outside 

 with Izal double strength solution. (See page 21.) 



Entice your bees to a prepared water fountain and 

 charge its water with one teaspoonful of Izal to every 

 ten pints of clean fresh water. The fountain should be 

 situated in a conspicuous though protected place m the 

 apiary. 



Active. — Once the disease is diagnosed as present, it 

 is wise ta fight it by germicidal procedures which depend 

 in their degree of utilisation on the course the disease is 

 taking, the time of the year and other practical con- 

 siderations. You are, therefore, the best judge as to 

 when weather or other conditions will compel limiting 

 or modifying your procedures.
