CONTROL OF THE CODLING MOTH IN NEW MEXICO. 5 
It would appear that with the minimum of three applications, || 
made as shown in Table IJ, injury from the codling moth in the Pecos | 
Valley may be reduced to less than 5 per cent of the total crop of i 
apples produced. For each of the two additional applications an | 
increase in sound fruit is shown, but probably not in proportion to | 
the expense involved. It should be borne in mind, however, that in | 
these experiments applications were made with much thoroughness, 
| and unless the orchardist will do equally as thorough work it will be 
| better for him to make the additional applications. 
: . PLACES OF ENTRANCE OF FRUIT BY CODLING MOTH LARV. 
| Many observations in different parts of the country have shown 
' that the majority of codling moth larve normally enter the apple at

the calyx end. A careful study of the places of entering sprayed 
fruit by larve, whether at calyx, side, or stem, throws much light 
on the relative effectiveness of the respective spray applications. 
All experiments corroborate the statement that the treatment given | 
immediately after the falling of the petals is by far the most im- 
portant one and that its omission ean not be corrected by subsequent 
treatments, however thoroughly made. 
A study of the behavior of the calyx lobes of the recently set 
apples in the Roswell section furnishes evidence of value in timing 
spray applications. Ordinarily in the Fast there is a period of about 
10 days following the dropping of apple blossoms during which the
