REPORT OF THE STATE ENTOMOLOGIST I915 



21 



It will be seen from the tabulation on page 20 that the yield of 

 individual trees in plot 1 ranged from 311 to 1819, an undesirable 

 variation so far as making close comparisons are concerned. The 

 number of wormy apples varies approximately with the yield except- 

 ing in the case of tree A which had 135 or over 24 per cent of the 

 total yield wormy. A note made at the time of spraying shows that 

 one corner of this tree was not covered so satisfactorily as some of 

 the others. Excluding this tree, the percentage of wormy fruit 

 varies from 8. 87 to 17.53. It will be observed that in each instance 

 a large percentage of the infestation is in the side of the fruit and 

 due to late-hatching caterpillars of the first brood. The average 

 percentage of wormy fruit for the plot is 13.52 per cent, while the 

 side injury, due to eggs hatching in July, amounts to 9.49 per cent.

The trees on plot 2 bore a more uniform crop, the apples on indi- 

 vidual trees ranging from 590 to 1395 and the infestation by the 

 codling moth is likewise somewhat uniform, the percentage of
