446 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



commonly used in vineyards is useful in this work, but a hand- 

 hoe will need to be used to throw the earth away from the imme- 

 diate base of the vine. The soil should then be kept well stirred 

 by cultivation at frequent intervals, all of which is merely part 

 of good practice, independent of the control of the root-worm. 



The Grapecane Gall-maker * 



The Grapecane Gall-maker is a small reddish-brown snout- 

 beetle about one-eighth inch long, which lays its eggs in the 



canes, giving 

 rise to galls 

 about twice the 

 diameter of the 

 cane and 1 or 

 1J inches long, 

 with a deep scar 

 in one side. It 

 has been noted 

 as injurious in 

 Ohio and West 

 Virginia, and 

 from the records 

 seems to be gen- 

 erally distrib- 

 uted over the Eastern States, but is by no means a 

 serious pest. 



Life History. The adult beetles appear in May 

 and are gone by early July. They feed sparingly 

 on the vine, making little pits in the tendrils, in the 

 buds or bark of new canes or in the midribs on the 

 under side of the leaves. The females soon lay their 

 eggs and make the egg scars. These cause the galls
