the importance of the treatments made after the buds show green 

 and before blossoms appear. Systematic sjraying of orchards by 

 an approved spraying schedule, and cultivation of orchards are 

 recommended. 



CHERRY MAGGOT 



A littlo-known cherry maggot has been discovered. This new 

 species prefers the sour cherry and was found in abundance at 

 Ithaca and Trumansburg. At the latter place it was found in com- 

 pany with the older cherry maggot. The first flies appeared on 

 June 9 in a neglected cherry orchard and it was found that these 

 flies deposited their eggs on June 24. Fifteen days therefore 

 elapsed between the time of the appearance of the fly and the time 

 the eggs were deposited. The spraying should be done within this 

 period. The mature maggots were found on July 10 ; first spraying 

 made on June 10, the day after the first flies appeared. The mix- 

 ture used was as follows: Two and one-half pounds arsenate of 

 lead, one and one-half gallons of cheap molasses, fifty gallons of 

 water. The second spraying was done two weeks later. The fly is 

 similar to the house fly in habits, going about sipping materials 

 from the surface of fruit and leaves. No effort was made to get 

 the spray on the tops of the trees, and the number of clean fruit 

 seemed to show quite plainly that the spray mentioned will control 

 the pest. The important thing to do is to reach the fly before it 

 deposits the eggs. The cherry fly looks very much like the apple 

 maggot fly except that one of the black bands on the wings has a 

 white spot as if punctured. 



APPLE MAGGOT 



The apple maggot is largely controlled by ordinary spraying 

 with arsenate of lead as for codling moth, and good cultivation of 

 orchard. The application of the sweetened poisoned bait as for 

 the cherry maggot has, during the past two years, completely con- 

 trolled the apple maggot. When thoroughly mixed and sprayed 

 upon the lower part of each tree, a few branches being covered, the 

 adult flies will feed upon the poison and be killed before the 

 eggs arc laid. This remedy should be applied when the first adults 

 of each brood appear, approximately about July 1 for the first 

 brood, and August 20 for the second.
