Owing to the rudimentary condition of 

 the wings of this insect, it does not pass 

 rapidly from one field to another, so trouble 

 from this source would be considerably 

 modified by a good system of rotation. If 

 plants are to be taken from old beds they 

 should be removed before the insect lays 

 its eggs. Spraying in the fall with arsenates 

 will result in the destruction of many of the 

 beetles. The burning over of old beds after 

 picking the crop is very beneficial in destroy- 

 ing great numbers of these insects. 



Leaf eaters. — The most injurious insect 

 of the strawberry is the leaf roller. This is 

 a small, brownish caterpillar that folds one 

 of the sections of the leaf of the strawberry 

 by fastening the upper surfaces together 

 with very fine silken threads, feeding upon 

 the enclosed surface until the leaf turns 

 brown. When the larva is full-grown it 

 is about half an inch long. It then pupates, 

 or rests, inside the rolled leaf, emerging as 

 a moth in midsummer, being in turn able 

 to lay eggs for a second brood of cater- 

 pillars, even three or four broods a year 

 being hatched in the Southern States. 



The remedies are simple, consisting of
