It will be noted from the foregoing table that the unsprayed trees 
(Plat I) show 77.79 per cent of fruit free from the codling moth, which 
is a lighter injury than usual for that section. 
larvee covering the season 1909, taken from trees in another orchard, 
show that only 13 per cent of the first-brood larve transformed to 
moths, and hence the second brood was comparatively light. 
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. 
42,818, and 42,867, giving a total of 123,560. 
The effect of the treatments on the places of entrance of fruit by 
larvee of the first and second broods is shown in Table XVIII.
