FRUIT INSECTS 



difficult to hit them 

 with a spray. Much 

 may be done, how- 

 ever, to lessen their 

 numbers by keeping 

 down all weeds, not 

 only in the field itself, 

 but along fences and 

 in other waste land. 

 Stone piles and fences, 

 rubbish heaps, sodded 

 driveways and near- 

 by woodlands furnish 

 hibernating quarters 

 for the adults, and 

 should be avoided 

 whenever possible. 

 The young may be 

 killed by spraying 

 with kerosene emul- 

 sion or tobacco ex- 

 tract and soap, but 

 this treatment is not 

 effective against the 

 adults. It has been 

 suggested that in 

 nurseries and straw- 

 berry beds the adults 

 may be captured by 

 means of a butterfly net. While this method may be useful in 

 the small garden, it is not adapted for use on a large scale. 

 The control of the tarnished plant-bug in the nursery, on 

 asters when grown for seed and in commercial strawberry fields 

 is still an unsolved problem.
