PARASITES OF GIPSY AND BROWN-TAIL MOTHS. 



THE BROWN-TAIL MOTH AND ITS PARASITES IN EUROPE. 



Reference has already been made to the fact that in those sections 

 of Massachusetts in which both the gipsy moth and the brown-tail 

 moth occur, the latter is considered as the lesser pest of the two. 

 This opinion, as held by those who are thoroughly familiar with the 

 comparative noxiousness of the two, speaks quite plainly of the char- 

 acter of the gipsy moth as a pest, in view of the very considerable agi- 

 tation which has come about on account of the brown-tail moth in

localities into which it has preceded the gipsy moth or where the latter 

 has not as yet reached a state of destructive abundance. 



On account of the lesser interest aroused .in the brown-tail moth in 

 Massachusetts, its parasites have not been given quite the considera- 

 tion, in some respects, that has been given to those of the gipsy moth, 

 but this lack of consideration has had entirely to do with the question 

 of the future policy of the laboratory, and has not extended to the 

 actual handling of the parasites themselves. In every respect other 

 than as a basis for calculations as to future policies of the labora-
