THE PLUM CURCULIO AN ENEMY TO APPLES. 



(Paper read before the State Horticultural Society at its 1904 meeting.) 



That this pest, which we associate so commonly with plums, does 

 attack apples, is not a new fact, since this departure from the orthodox 

 food habits has been known for some time ; but since appje-raising in 

 Minnesota is, practically speaking, in its infancy, this naughty feature 

 in the life of this weevil, illustrated by the loss, in at least one instance, 

 of 100 per cent of the apple* crop in a Southern Minnesota orchard 

 last season, is unceremoniously brought to our door in a very em- 

 phatic and unpleasant manner. Fourteen other orchards have suf- 

 fered, to my certain knowledge, and there are probably many other 

 instances of its work in apples in this state not known to me. I 

 might add that I placed some of these injured apples in a breeding 

 jar and in September had a fine lot of Plum Curculios from the same.
