calyx lobes remain open, so that the spray may be successfully 
directed into the calyx cups. In New Mexico, however, it would 
appear that the calyx lobes of the little apples do not draw together 
nearly so quickly after the falling of the petals and may remain 
open in suitable condition for calyx spraying for a period of from two 
to three weeks, varying somewhat with the variety and season. 
(Figs. 3 and 4.) 
This condition renders it possible to apply the second spray in a 
way to supplement the first spray into the calyx cups.

The effect of spraying in changing the relative proportion of larve 
which succeed in entering the fruit at the calyx, side, and stem is 
shown for Plats I to WI in Table III. The normal behavior of the 
larvee in entering the fruit may be seen by referring to the figures for 
Plat IV of this table. It will be noted that on the unsprayed plat | 
somewhat over one-half (53.72 per cent) of the total larve for the 
season entered the fruit at the calyx end.
