from the tdve. Since there may be developmental stages not affected 

 by the first treatment, the operation should, after an interval, be 

 repeated to remove those which in the meantime have reached the 

 adult stage. 



A safe method has just been recommended {1) which if satis- 

 factory has more in its favor than the methods just suggested. This 

 is that, since weak, listless colonies are the ones which harbor Braula, 

 the infested colony should be opened in the evening and sprinkled 

 thoroughly with honey water. Then, in cleaning up the dilute 

 honey, the bees are said to remove the Braula. None of these 

 methods has as yet been tested in the United States. 



CONCLUSIONS 



It "appears from the available information that Braula is not a 

 serious pest of the apiary and that no great harm is to be anticipated 

 from its unfortunate establishment in this country. It is, of course, 

 not certain that it will remain here. This introduction, however, 

 should not be considered as unimportant, and wherever Braula 

 occurs steps should be taken to eradicate it from the infested colonies. 

 With such a visitant of the bee colony, it is impossible to determine 

 in advance what effect it may have in some other portion of the 

 country, and every means should be taken to eradicate it if possible, 

 especially since the infested area seems to be small at present. In- 

 spectors of apiaries who find this insect in colonies inspected by them 

 will do well to recomimend its removal. More work is needed on 

 the life history and especially on the feeding habits of the species.
