In the case of the sprayed plats, as would be expected, the propor- 
tion entering at the calyx is greatly reduced, and there is a corre- 
sponding increase in the proportion entering the fruit at the side and 
stem. There is considerable variation, however, as to the number of 
larve entering the fruit at the calyx, side, and stem in the several 
sprayed plats, which is of significance in connection with the charac- 
ter of the treatments given. To better compare these points, Table 
IV has been prepared, which requires but little in the way of com- 
ment. A comparison of Plats I and III, both involving the one-spray 
method, shows, as to calyx entrance for the two broods, a difference 
in favor of a coarse as against a mist spray of 17.05 per cent in les- 
_ sening calyx entrance and a corresponding increase in number entering 
at side. As between Plats [and IV a still more marked difference is 
shown, namely, 38.85 per cent in favor of a coarse drenching spra 
in preventing entrance at the calyx.
