combs during the season with a dilute Izal solution is 

 a good practice. Since the queen is the Hfe centre of 

 the colony, it is sound practice not to tolerate poor 

 queens in the apiary. See that your hives are water- 

 proof and your colonies are provided with porous dry 

 packings. 



Active Treatment. — (1) Remove the cause by taking 

 out of the hive of the affected colony, combs with pollen 

 which appears to be mouldy or " stale " and replace 

 with clean combs. 



(2) If the queen is failing, re-queen at the earliest 

 opportunity with a young queen from a reputable strain. 



(3) Stimulate with medicated cane sugar syrup. By 

 such active treatment the disease is quickly brought 

 under control and the affected colony saved. 



N.B. — For Izal dilutions and medications see
