Cylas f ormicarius Fabricius . 



The sweet potato weevil is found commonly in Victoria 

 County and is the great pest of the sweet potato (Jpouura 

 batatas) crops. It breeds natively in the roots of a Convol- 

 Tulvus sp., commonly known as "tie-vine," in which it has 

 been taken in all three stages in January. The weevil breeds 

 in the sweet potato tubers in the field and continues its work 

 all winter in the stored roots, until every potato is honey- 

 combed with its cells. The larvae give the potatoes a bitter 

 flavor, rendering them unfit for food, even for hogs. The 

 dult is a slow insect and is dependent largely upon the assist- 

 ance of man for transportation to new territory.
