PESTS OF GARDEN AND FIELD CROPS 



The Oblique Banded Leaf Roller (Archips rosaceana Harr.) 

 Roses and other plants in greenhouses and occasionally fruit tree 

 foliage sometimes are badly injured by active, green or reddish cater- 

 pillars, three fourths of an inch long, which roll up the leaves, 

 fasten them with silk, and feed within. The cater- 

 pillar has an indistinct darker stripe down the 

 middle of the back, the head is dark brown or black, 

 the segments of the body are rather distinct. The 

 adult is a brownish, smooth moth, and emerges from 

 a pupa formed within the rolled leaves.

Hand picking is often the best means of control, though a prompt 

 use of Paris green or arsenate of lead will check the pest, pro- 

 vided the application is made before most of the larvae have retired 

 into rolled-up leaves. 



The Bean Leaf-roller 



(Eudamus proteus Linn.) 



Rather odd-appearing 

 worms, 1^ inches long 

 when mature, with narrow 

 neck and prominent head, 

 eat the leaves of beans 

 and sometimes other leg- 

 umes. The ground color 

 of the larva is yellow, and 

 its body is dotted with
