REPORT OF THE STATE ENTOMOLOGIST I9IO 2J 



311 or nearly 19 per cent of the total, were found on tree B, less 

 than .5 per cent of these being also end wormy. The minimum 

 number of side or end and side wormy apples was found on tree F. 

 This was 144 or 16.3 per cent of the total yield, less than ,4 per 

 cent being also end wormy. The entire plot produced 8135 apples, 

 of which 1298, or 15.9 per cent, were side wormy or end and side 

 wormy, the latter being a practically negligible quantity. 



Plot 2 had the minimum yield of 134 on tree E, 79.09 per cent 

 being sound. The maximum number of apples, 2258, was produced 

 by tree B, which yielded 86.94 per cent of sound fruit. This tree 

 also produced the maximum number, 295, of wormy fruit, amount- 

 ing however, to but 13.06 per cent of the total yield. The smallest 

 number of wormy apples, 28, was found on tree E, and constituted 

 20.91 per cent of the entire product. Percentage comparisons are 

 very strongly in favor of B, though as an actual fact it bore ten 

 times as many wormy apples. The maximum number of side 

 wormy or end and side wormy apples, 276, occurred on tree F, and 

 com.prised 15.8 per cent of the entire product, less than 2 per cent 

 of the whole yield being end wormy. The minimum number of 

 side wormy apples, 25, were found on tree E and amounted to 18.6 

 per cent of the total yield, less than 2 per cent being end wormy. 

 Here again we see the injustice of strictly percentage comparisons, 

 since F had ten times as many wormy apples as E, yet the per- 

 centage of sound fruit is strongly against the latter. This plot as 

 a whole produced 7316 apples, 1084 or 14.8 per cent being side 

 wormy or end and side wormy. A comparison between plots i and 

 2 shows a gain in sound fruit from the second spraying of only 1.37 

 per cent, though there were 247 less wormy apples on plot 2 than 

 on plot I . 



Plot 3 presents an entirely different set of conditions, since it was 

 ■sprayed but once and then in early June. The minimum tree C 

 yielded but 315 apples, only 36.19 per cent being sound. The 

 maximum tree D produced 1708 apples, 64.17 per cent being free 

 from worms. The wormy apples range in number from 811 in tree 

 A to 201 in tree C, comprising 54.80 per cent and 63.81 per cent, 

 respectively, of the entire product. The maximum number of end 

 wormy or end and side wormy apples was found on tree A with 

 its 448 thus classed, forming 30.2 per cent of the entire yield. The 

 minimum number of "j^ was produced by tree C and comprised 24.1 

 per cent of the total. The entire plot yielded 7594 apples, 1754 or 

 23 per cent of the total being side wormy. The plot as a whole 

 yielded but 57.35 per cent of sound fruit, showing a marked dis- 

 crepancy between it and the two preceding plots.
