tervals of a few inches throughout the length of the tunneled portion 

 of the canes; they are small, being about one-third of the diameter 

 of the burrow; and their object is to enable the larva to deposit its 

 excrement outside of the burrow." 



Remedies. "The methods of combating this insect are simple, but 

 they require prompt attention. As soon as the tips of the canes begin 

 to droop they should be cut off below the point where they are girdled. 

 In this way the larva can be destroyed before it has begun to bore into 

 the lower portion of the cane, and thus only the tip of the cane will 

 be lost. When, however, the first indication of the presence of this 

 pest is the dying of the entire cane, caused by the boring of the larva, 

 the infested canes should be promptly cut out and burned. These 

 canes can be readily recognized by the dying of the leaves and by 

 the small holes in them described above. They are most likely to 

 be observed at the time of the blackberry harvest. It is of the ut- 

 most importance that the cutting and burning of these canes should 

 be done promptly. For if it be delayed till autumn, the larvae will 

 have penetrated the roots and will then be beyond the reach of the 

 pruning shears."

THE STRAWBERRY WEEVIL (FIG. 32) 



Anthonomus signatus, Say 



Although this insect is primarily known as a strawberry pest, 

 where its injury is most common and most serious, it breeds in the 

 buds of wild blackberries and dewberries and 

 some other plants. At times, when abundant, it

 It is a small curculio or snout-beetle, about one-

 shinin S wing-covers varying in color from black to 

 reddish brown, but with a large black spot on each. 

 The insects hibernate in the beetle stage, under rubbish, especially 

 in woodlots and hedge-rows. In spring they appear and begin feeding 

 on immature pollen, then deposit their eggs in the unopened buds
