ATTACKING THE ROOTS. 231 



This insect inhabits the Middle, Western, and some of the 

 Southern States. It is said to have been exceedingly destructive 

 in North Carolina both to wild and cultivated grapes, and is 

 reported as injurious also in Kentucky. The moth is found 

 in the South from the latter part of June until September. 



It is stated that the Scupperuoug grape, a variety of the fox- 

 grape, Vitis vulpina, is never attacked by this borer ; if this

 roots of the Scuppernong. When it has been ascertained that 

 the borers are at work on a vine, the earth should be cleared 

 away from above the roots and the invaders searched for and 

 destroyed ; hot water applied about the roots is said to kill 

 them. As a preventive measure, mounding the vines, as 

 recommended for peach-trees, under the head of the peach- 

 tree borer, No. 97, would probably be beneficial. 



No. 125. The Grape Phylloxera. 



Phylloxera vastatrix Planchon. 



This tiny foe to the grape-vine has attained great celebrity 

 during the past few years, and much attention has been paid 

 to the study of its life-history and habits, in the hope of 

 devising some practical measures for its extermination. The 

 destruction it has occasioned in France has been so great that 

 it has become a national calamity, which the government has 

 appointed special agents to inquire into; large sums of money 

 have also been offered as prizes to be given to any one who
