136 DECIDUOUS FRUIT INSECTS AND INSECTICIDES, 
The influence of the treatments on the places of entrance of fruit 
by the larve of the first and second broods combined for the respective 
plats is shown in Table XVI.

For more ready comparison of the efficiency of the treatments, 
Table XVII is given, from which it will be seen that the demonstra- 
tion and the one-spray treatments were about equally effective in 
protecting the calyx and that neither was satisfactory in controlling 
worms entering the side. The difference in total efficiency between 
the demonstration and the one-spray plats is quite small, namely, 
1.06 per cent in favor of the former. The unsprayed trees show 46 
per cent of wormy fruit, so there is a total saving of 38.44 per cent 
of the crop by the demonstration treatment and 37.68 per cent by 
the one-spray.
