INJURIOUS INSECTS OF 1904. 



Remedy: Cut off the portions containing the rows of punctures, and 

 burn. This is best done in early spring or late fall. Shaking the bushes will 

 sometimes dislodge the full-grown insects. 



2. Tips of shoots of raspberry wilting; two rows of punc- 

 tures one inch apart at base of wilted portion, with a 

 small hole between. Canes are burrowed to the base 

 before autumn.

Remedy: Look over bushes occasionally in June and early July and 

 remove all withered tops. Be sure to cut low enough to catch the borer, and 

 destroy the portion cut off, with contained grub.
