In Tables 12 and 13 will be seen the data obtained from examinase — 
tions of the bands and traps. From 56 banded trees 8,805 larve 
and pupe, or an average of 157.23, were taken, and from 20 codling- 
moth traps 3,941 larvee, pupz, and moths, or an average of 197.05, were 
secured. The destruction of so large a number of individuals should 
aid gradually in obtaining better control despite the fact that the 
experimental data for this, the first year, indicate otherwise. 
Part of the orchard of Charles Lamb near Highland Park was also 
used for the codling-moth trap experiments. This was sprayed by 
the grower who used the short rod equipped with a Bordeaux type 
of nozzle in making all the spray applications. In addition to the 
calyx treatment, six cover sprays were applied. Plat I was sprayed 
and trapped, plat II was sprayed, and plat III was untreated. 
The results of the fruit examinations of eight trees in each of plats 
I and II and four trees in plat III are given in Table 14. In plat I, 
which was sprayed and trapped, 50.54 per cent of the dropped and 
harvested fruit was free from worm infestation; whereas in plat II, 
which was merely sprayed, there was 64.54 per cent of uninfested 
fruit. The unsprayed plat produced 11.45 per cent of fruit free 
from larvee. 
It will be noted in Table 15 that 5,512 larve, pupe, and moths 
were collected from 20 codling-moth traps and that the average per 
trap was 275.6. 
In the Smith experimental orchard, where the principal spraying 
experiments of 1917 were conducted, examinations were made of 20 
codling-moth traps in plat I and of 15 in plat V. The results are 
presented in Tables 16 and 17, in which it will be seen that in plat I, 
6,186 larvee, pups, and moths, or an average of 309.3 per trap, were 
secured, while in plat V a total of 4,673 or an average per trap of 
311.53 individuals were captured.
