In the foregoing table the demonstration plat shows an increase of 
sound fruit over the one-spray method of 4.05 per cent and over the 
unsprayed plat of 19.87 per cent. There was less injury on the 
unsprayed trees than usual for that section, due to the small size of 
the second brood. Only 18 per cent of the first-brood larve from 
bands transformed to moths. 
The effect of the treatments on the places of entrance of fruit by 
larve of the first and second broods is shown in Table XXI.
