At Florence (table 15), as in table 14, both larvae and punctures 
were grouped together. The efficiency for the schedule for both 
combined was 99.86. The results of the year's work clearly indi- 
cate that the damage caused by the plum curculio can be greatly 
reduced by spraying. 
EXPERIMENTS IN 1914 
During this season both larvae and punctures are grouped 
under the same heading. The damage done by curculio this 
year was very light.
