68 PRACTICAL QUEEN REARING 



difference of opinion as to the proper age of larvae, but all 

 agree that larvae more than three days old should never be 

 used. Nobody holds that better queens can be reared from 

 larvae two days old than from younger larvae, although some 

 think that as good results can be obtained. The majority seem 

 to favor larvae from twelve to twenty-four hours old, with some 



Fig. 27. Larvae not to exceed thirty-six hours old should be used for 



grafting.
