GRAPEVINE ROOT WORM 55 



visit the sections of most importance with very little loss of 

 time. Some very precise and significant statements were 

 obtained from Mr T. S. Clymonts of Cleveland O., who is not 

 only a grower but also a dealer and one who undoubtedly has 

 as good a general knowledge of local conditions as any one in 

 that section. He states that in the Ohio belt, extending east 

 and west of Cleveland, from Painsville to Avon and reaching 

 back 5 miles from the lake, there has been a reduction in ship- 

 ments of fully two thirds during recent years. In 1894 2000 

 carloads of grapes were shipped from that section. This was 

 reduced in 1900 to 900 and in 1901 to 600. Mr Clymonts esti- 

 mated the output for the present year as not over 500 carloads. 



He states that this reduction is due to various causes, the 

 principal ones being the ravages of the grape root worm, the 

 destruction caused by rot, and the prevailing low prices. He 

 attributes fully one third of the entire reduction to the beetles' 

 work and instanced a number of cases where vineyards of con- 

 siderable size had been killed by the operations of this pest. He 

 mentioned one vineyard of 60 acres, another of 25 acres, and 

 stated that innumerable small pieces had been destroyed by the 

 work of this insect. He states that the yield of one 60 acre 

 vineyard has been cut from 10-12 carloads to 35-40 tons by its 

 operations. Mr Clymonts observations led him to think that as 

 a rule the younger vineyards, specially those planted in the last 

 10 or 12 years, suffered most and that the old ones escaped with 

 comparatively little harm. The most destructive work observed 

 by him has been on sandy soil, or on ridges in other pieces. He 

 also states that vines set in an infested vineyard to fill vacancies 

 do not thrive and are usually killed by the insect. 



Mr J. W. Maxwell of Euclid states that 50$ of the vineyards 

 are dead in that section and that in his opinion a large propor- 

 tion of these have died as a result of the operations of this 

 insect. His crop of grapes in a large vineyard was reduced 

 fully one fourth, the most of which he attributes to this pest. 

 He states that the Wordens and Brightons are killed first, while 

 the Concords and Catawbas are not so badly injured.
