DISEASES AND ENEMIES OF BEES.

from the egg it is difficult to discern them with the naked 

 eye. Their rapidity of growth depends as much on the 

 temperature in which they are placed, as upon their good 

 living. A few days of hot weather may develop the full- 

 grown worm, which would require weeks and even 

 months in a lower temperature. 



The larva, after spinning its cocoon (fig. 93), soon 

 changes into a chrysalis, and remains inactive for 

 several days, when 

 it makes an open- 

 ing in one end, and 

 crawls out. The 

 time necessary for 

 this transforma- 

 tion is also gov- 

 erned by the tem- 

 perature, although 

 I think but few ever pass the winter in this state. A moth 

 will rarely be found before the end of May, and not 

 many are seen until the middle of June ; but after this 

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

DESTKOTED BY SEVERE COLD. 



3Ir. Quinby's experience, as well as my own, leads me 

 to differ with some modern writers on this point, and I 

 am compelled to maintain, that if combs containing eggs 

 or larvae are exposed to the severe cold of our northern 

 winters, not a single worm will be produced before the 

 middle of June, or until some moth, matured in another 

 hive, has had access to the combs, and an opportunity to 

 deposit her eggs therein. 



REMEDIES. 



It has already been observed that the Italians are much 

 less liable to be disturbed, or injured by the bee-moth,
