94 INSECTS AFFECTING THE STRAWBERRY. 



Professor Forbes, " the adults pass the winter under 

 rubbish and matted vegetation in a variety of 

 situations. With the earliest warm days of spring 

 they venture forth and collect upon whatever tender 

 vegetation of tree or shrub offers them a supply of 

 sap within the reach of their rather slender beaks. 

 On their food plants they lay their eggs. The young 

 soon appear, mingled with the adults as early ;i> the 

 latter part of April and the first of May (in Southern 

 Illinois) and feed -with them side by side. By the 

 middle of May the older individuals have matured, 

 and then all stages may be found together upon the 

 same plants; but the winged forms scatter widely, 

 and in June and July are generally distributed 

 wherever suitable food occurs." There are two, and 

 perhaps more, broods each season. In autumn the 

 adults are to be found abundantly upon goldenrods, 

 sunflowers, asters and various other fall flowers. 



Remedies. — As these bugs obtain their food by 

 sucking, they cannot be destroyed by coating their 

 food plants with poisons. The application of pyre- 

 thrum (insect powder) has proven the most success- 

 ful remedy. By means of a powder gun it can be 

 applied quite readily. Kerosene emulsion also de- 

 stroys them ; and it is claimed that the bugs can 

 frequently be collected in insect nets with profit. 



Other Strawberry Insects. 



The strawberry is subject to attack by a large 

 number of insects besides those discussed above.
