REPORT OF THE STATE ENTOMOLOGIST 



I915 



27 



It will be seen from the tabulation on page 26 that the yield of 

 trees in plot i ranged from 460 to 1751, a rather wide variation 

 which is not accompanied by a corresponding difference in the number 

 of wormy apples. The percentage of the latter on individual trees 

 varies from 17.67 to 44.78, the lowest percentage being upon one of 

 the most fruitful trees, while the highest was, as m.ight be expected, 

 on the tree producing the smallest crop. The average percentage 

 of wormy apples for this plot was 27.67, the injuries by late-hatching 

 larvae amounting to 25.34. Even in the case of the tree with the 

 lowest percentage of wormy apples, by far the most injury resulted 

 from the late egg deposition, this being 16.79 per cent out of a total 

 of only 17.67. The damage resulting from end wormy infestations 

 was almost negligible, it amounting to half of i per cent.

The yield on plot, 2 was low and more uniform than in the case o 

 plot I, the number of apples to each tree ranging from 331 to 1016, 

 while the percentage of wormy apples to each tree was fairly uniform
