 IJOSE LEAVES INVESTED WITH LEAF-ROLLING SAWELY. 



Th« larvce of Blenocampa pusilla rolJ the leaves into a tube, as sliown in 

 illustration, and then feed on them. 



IiEMEDiES. — All the leaf -feeding larvoe may be destroyed 

 by sprinkling the foliage with sulphur or hellebore 

 powder, or syringing with one of the standard insecti- 

 cides now on the market. Where only a few of the larvae 

 are to bo seen, hand-picking is the best plan to adopt. In 

 the case of the pith-boring kinds, cutting off and burning 

 any shoots that show signs of witheriiig suddenly will 

 make sure of getting rid of these jDests.
