THE STRAWBERRY 



INSECT ENEMIES OF THE FOLIAGE 



The transformations of the Strawberry Slug 

 have been well represented by Dr Riley in the figure 

 on page 86. The four-winged fly (3) appears in 

 spring, and deposits its eggs within the tissues of the 

 leaf or stem. The larvae feed upon the leaf, gnawing 

 small, circular holes at first. They develop in five or 

 six weeks into pale green worms (4, 6) about three- 

 fourths of an inch long. The larvae now go slightly 

 beneath the soil surface, and there they form cocoons 

 (7) within which they change to the pupa state (i, 2), 

 and later emerge as flies. In the southern states there 

 are two broods each season, while at the north there 

 appears to be but one. 



Remedies — On the non-fruiting plantations this 

 pest may be destroyed by spraying or dusting with 

 hellebore or arsenate of lead. On fruiting plantations 

 this method may be used in localities where a second 

 brood of larvae appears after the fruit is gathered. 



The Strawberry Leaf-roller is a small, brown- 

 ish caterpillar that folds the leaflets of the strawberry 

 by bringing the upper surfaces together and fastening 

 them by silken cords, and feeds upon their substance 

 till they look brown and scorched. It hatches from 

 eggs laid in spring upon the strawberry plants by a 

 small reddish-brown moth. The larva attains its full
