THE PESTS OF THE KASPBERRY. 



or 



Mammoth Cluster. A very large, late variety, covered with an 

 abundance of bloom; of good quality, hardy and productive. 



Gregg. A late variety of large size, finer quality and with less 

 bloom than the last ; very productive but not as hardy as the other 

 varieties described. 



Yellow-cap. This is an old variety, very common in old gar- 

 dens ; of fine quality, but the Caroline, described under Red 

 Raspberries, is superior in quality, productiveness and hardiness. 



Shaffers. A cross between the Red and Black-cap Raspberry; 

 fruit large, dark red and very acid; valuable for preserving; very 

 vigorous and productive. 



INSECTS. Few insects are destructive to the Raspberry 

 blackberry. The Root-Borer (JSgeria 

 rubi) Fig. 69, a being the male and b 

 the female, is a small, wasp-like moth, 

 resembling the peach-borer somewhat, 

 but smaller. The .eggs are laid dur- 

 ing June and July, on the canes near 

 the ground. The egg hatches, and the 

 larva eats into the pith of the cane 

 and passes down into the root. Here 

 it continues feeding until the following 

 spring, when it comes up through the 

 center of another cane, where it un- 

 dergoes its changes and comes out the 

 perfect moth, as illustrated. The in- 

 jured canes generally are destroyed 

 early in the summer. 



Remedy. The presence of the Root- 

 Borer is generally made known by the dying of the new canes 

 early in the summer, and the remedy is to cut until the worm is 

 found. 



A few other insects are sometimes injurious to the Raspberry 

 and blackberry, but not so much so as to warrant description in 

 so limited a work as this.
