KASPBEKRY. 141 



The number of insects that infest the Raspberry and 

 Blackberry is very few indeed, and none have as yet be- 

 come very common or destructive. 



The Blackberry bush borer, fig. 57, is occasionally found 



eating out the pith of the young canes of the Raspberry 



-sw s* and Blackberry, but it is not common. The 



YV// beetle, which is the parent of the borer, is 



pM^ about a half inch long, black, rusty yellow 



/A on the breast, and on the top of the thorax.

Fig 57 -BLACK- f t ^ ie Blackberry and Raspberry, generally 



BERRY BUSH at the base of a leaf. The grub penetrates 



BORER. ^ e s tem, eating out the pith, causing the 



young canes to wither. A few of my Blackberry bushes 



were attacked by this insect the past season. 



The infested canes should be pruned off in the fall and 

 buried. In Europe there is a beetle (Byturustomentosvs), 

 which deposits its eggs in the flower of the Raspberry, which 

 produce small white maggots by the time the fruit is ripe. 

 A similar worm is quite common upon our Wild Red 

 Raspberry, but whether it is the same as the European 

 species, or one of the Ortalidians, (some of which are known 

 to deposit their eggs in the Raspberry), I am unable to say, 

 as they are seldom seen upon the cultivated varieties.
