CHAPTER XIT 



STRAWBERRY INSECTS 



Strawberry plants are at the most short-lived ; they are 

 low growing and are usually cultivated in closely set rows. 

 Strawberry growing is more akin to the raising of field crops 

 than to the cultivation of other fruits. Likewise in the control 

 of strawberry insects less reliance is placed on spraying and more 

 attention is given to crop rotation, fall plowing, clean culti- 

 vation, and similar practices. The one-crop system of straw- 

 berry culture as now practiced by the majority of commercial 

 growers greatly simplifies the problem of insect control. This 

 is especially true in the case of white grubs, root worms and other 

 under-ground insects. 



The Strawberry Leaf-roller 

 Ancylis comptana Frolich 



Throughout the Northern states and Canada, from Colorado 

 eastward, strawberries are often seriously injured by a small 

 greenish or brownish caterpillar which folds the two halves 

 of the leaflets together and feeding within the shelter so formed 

 causes them to turn brown and die. In years of great abund- 

 ance the injury may be very severe; the foliage is destroyed 

 and the fruit fails to mature. 



The parent moth measures about J inch across the expanded 

 wings ; its general color is light reddish-brown and the fore 

 wings are marked with wavy bands of white and darker brown.
