Remedy. — The remedy is the same for all three of the borers. The 

 dead and injured canes can be told as soon as the buds are opening and 

 should at this time be cut out and burned. This will destroy the borer 

 before it can mature and escape. 



THK SPAN-WOEM (Eyfitchia ribearia Fitch). 



The span, or looping caterpillar of 

 the currant and gooseberry, when it 

 appears in a locality, is usually quite 

 destructive by very quickly stripping 

 the bushes of their leaves. The cut 

 shows the caterpillar, natural size, in 

 a few of the many attitudes which 

 it assumes, and represents it so well 

 that no description is needed. There 

 is only one brood in a year and this 

 brood often has its numbers greatly 

 reduced by parasites.

The remedy is Paris green when it can be used without poisoning the 

 fruit, otherwise hellebore. 



THE YELLOW-LINED CURRANT BUG (Poe<nlocapsus Hneahts Fabr.). 



The injury done by this bug is in 

 puncturing the young leaves so that 

 little brown blotches appear and 

 later, when these spots become more 

 plentiful, the leaves will wither and 

 drop off. The bug is quick and active 

 and when approached dodges to the 

 other side of the leaf or drops to 

 the ground. The line at the right 

 of the drawing shows the natural 

 size of the bug. 



Remedy. — Spray with kerosene 

 emulsion.
