The spring of 1908 in that locality was cold and the beetles, which 
were not numerous, were much retarded in their movements. A total 
of 2,189 curculios was taken during the season. The jarred block 
shows a gain of only 6.71 per cent of sound fruit over the block not 
jarred. 
Also, at Barnesville, Ga., during 1910, a block of 336 trees in 10 
rows was jarred from March 10 to time of picking fruit (and subse- 
quently for other records). A check plat of 60 trees (10 rows of 6 
trees each) was laid off on one end of the jarred block. Counts of 
fruit for infestation were made on 20 trees of each plat, as shown in 
Table LXXXVIII. A total of 6,994 beetles was captured by July 30, 
when all fruit had been gathered.
