ENEillKS OF BKES. 34] 



A moth will rarely bo found before the end of May, and 

 not many are seen till the middle of June ; but after this 

 time they are more numerous till the end of the season. 



FKEEZING DESTKOYS THEif. 



It is well demonstrated that the moth, its eggs, larvfe, 

 etc., cannot pass the winter without warmth sufficient to 

 prevent freezing. It can be shown thus. Take all the 

 bees out of a hive in the fall, and without disturbing the 

 honey and comb, put it in a cold chamber where it can 

 freeze thoroughly. In the following March, introduce 

 bees, and when not contiguous to a stock containing 

 worms, not a single worm will be produced before the 

 middle of June, or until the eggs of some moth matured 

 in another hive have had time to hatch. Such hives may 

 be kept for swarms, without any appearance of worms. 



The discovery that worms and eggs can be frozen to 

 death, has led to a plan by w'hich the whole race of 

 moths can be exterminated from an apiary, and only re- 

 appear from those of neighbors. When aided by mov- 

 able combs, it is entirely practicable. I have tried it to 

 gome extent, but since learning that the Italians resisted 

 the moth so much more effectually than the natives, I 

 have not practiced it extensively. 



EXTBKMIKATION OF THE MOTH. 



It is simply to expose the combs, free from bees, to a 

 temperature of 18° below freezing, for ten to twenty 

 hours afler they are once thoroughly cold. To describe 

 more minutely, I would say that during December or early 

 in January, before the bees have nuicli brood, is the best 

 time. 



Take the hive to a dark room, using artificial light to 



keep the bees from flying. Take out one comb, with honey 



enough to last for several days, and put it in an empty 



hive. Set over this, another empty one of the same si«e,
