REPORT OF THE STATE ENTOMOLOGIST I915 



29 



The yield on plot 3 was so light that two special trees just to the 

 north and designated as trees A A and BB were also picked and the 

 fruit classified to see if the conditions on these trees varied materially 

 from those found to exist on the trees originally selected. The yield 

 of these two trees, as will be seen by referring to the tabulation, was 

 634 and 410 apples, respectively, the percentage of wormy fruit 

 being 32.33 and 39.26 per cent, with side injury amounting to 32.0T 

 and 38.53 per cent, respectively. In other words, here as elsewhere 

 in this orchard, a very large proportion of the wormy apples suffered 

 from the late-hatching larvae. 



Another tree designated CC was east of plot 2 and was supposed 

 to have had three sprayings. It was selected because of the rela- 

 tively large crop of apples, producing 3175. Here there was 20.44 

 per cent wormy, 18.96 per cent being classed as such because of the 

 side injury. The relatively high percentage of scab infection, 

 namely 47.14, indicates that this tree may not have been sprayed 

 so thoroughly as some others. AU three of these special trees, like 

 those in plot 3, are remarkable because of the almost total absence 

 of end- wormy apples.
