habit of the young larvae, recorded by a number of observers in 

 relation to those hatching from eggs deposited upon the foliage. 

 A few days after entering the fruit many of the larvae desert the 

 initial point of injury and make their way to the blossom, end. This 

 tendency to forsake an apparently perfectly satisfactory shelter is 

 probably an inherited one and is analogous to the action of the larva 

 leaving the temporary leaf mines in the search for fruit. 



Investigations relative to the prevalence of this type of injury 

 show its somewhat general occurrence along the south shore of Lake 

 Ontario and in the vicinity of Lake Erie, as evidenced by the follow- 

 ing observations. 



In an examination September i8th of a "tree-run " of greening 

 apples in the packing shed of Mr H. B. Eaton of Yoimgstown and 

 said to be below the average, the following conditions were noted: 589 

 apples were examined of which 73 showed a July side worm infesta- 

 tion, 2 a July and August side worm infestation, and 2 an August 

 side worm injury. 



In an Albion orchard a greening tree bearing fruit on one side and 

 presumably unsprayed, had practically 99 per cent wormy, there 

 being 2 to 4 or even 6 side injuries on individual apples. 



Counts in two Waterport orchards were kindly made by Mr A. B. 

 Buchholz of Albion and his data are as follows : 



In the orchard of B. G. Wilson, 438 Hubbardston apples were 

 examined with the following results: perfect, 345; side wormy, 

 July, 69; side wormy, August, 4; green fruit worm, 22. 



In the orchard of H. L. Brown, a lot of 529 Hubbardston apples 

 gave: perfect, 468; end wormy, o; side wormy, July, 34; green fruit 

 worm, 18. 



Mr Brown sprays but once for the codling m.oth and usually has 

 good results, though formerly he had considerable trouble with this 

 pest. It has taken him several years to bring the insect under 

 control. A later examination of over a barrel of " tree-run " Bald- 

 wins from Mr Brown's orchard resulted in finding 365 perfect apples; 

 58 scabby apples; 9 infested by leaf roller; 18 side wormy, the larvae 

 having penetrated deeply into the fruit in 6 of these. Approxi- 

 mately a bushel of Baldwins from an old orchard belonging to Mr 

 Brown was also classified with the following results: perfect, 75; 

 sooty blotch or scab, 57; roller and scab, i ; end and side wormy, i ; 

 side wormy, 3 ; side wormy, July, 19. 



Mr J. B. Achilles m.ade an examination of a sample lot of fruit in 

 a Batavia orchard and tabulated his data as follows: perfect, 55; 

 scab, 283; end wormy, 7; end and side wormy, 5; side wormy,
