Increase of Maggot in Untreated Orchards. 



In Bulletin No. 9 Nova Scotia Department of Agriculture, 

 1917, there is described the history of two orchards — orchards 

 No. 1 and Orchard No. 4 respectively — that were formerly ser- 

 iously affected with apple maggot, but which were made to 

 bear clean crops of apples by careful spraying. These or- 

 chards have now remained untreated for two years with re- 

 sults seen in the following counts from both drop and picked 

 fruit of Gravenstein apples. 



Examination of Apples Infested by Apple Maggot. 



Counts made last year in these orchards showed that this 

 pest was on the increase and this year's results show that the 

 increase is progressing and soon we may expect to see the in- 

 festation as severe as it was originally. 



These results may well be contrasted with those of another 

 orchard at Hantsport, N. S., which in 1916 exhibited an infesta- 

 tion of the utmost severity, the least susceptible variety, viz. 

 Golden Russet, showing a 68 per cent infestation. As a result 

 of following our directions for treatment for two years, the own- 

 er now reports practically a perfect crop, though indications 

 otthe presence of the pest can still be detected. 



Conclusion. 



The records contained in the foregoing were taken for the 

 the writer by Mr. J. P. Spittall, whose valued assistance is 

 hereby acknowledged.
