The Cherry Fruit-Fly. 29 



latter part of May in early varieties of cherries, and we have found 

 them in cherries left on the trees as late as August 5th. We also 

 saw many of what we believe to be the adult insect on the cherries 

 at this late date ; Mr. Lowe reports finding young maggots in fruits 

 as late as August 16th. Our Massachusetts correspondent reports 

 that some of his cherries began to " spoil " even before they had 

 fully matured. 



Varieties of Cherries Attacked. 



The European cherry maggot is said to confine its work to the 

 sweet and sub-acid varieties, but its new American congener seems 

 to be less particular in its tastes. The Massachusetts parties who 

 first called our attention to the insect write us that " all our cherries 

 w^ere badly infested, the Downer and the black ones, but the Morel- 

 los were the worst." At Ithaca, N. Y., only the early varieties are 

 reported infested ; while at Geneva, N. Y., the insect confined its 

 work this year mostly to the English Morello and the Montmorency 

 varieties, the latter being the worst infested. It thus seems that the 

 pest may attack all varieties of cherries whether sweet, sub-acid, or 

 sour, or whether early or late ; the Morello and Montmorency varie- 

 ties seem to have suffered the most this year. 



It May Attack Plums or Prunes. 



One grower at Geneva, JS^. Y., reports that he fears the same 

 insect worked in his prunes last year. Ten years ago maggots were 

 found working in both cherries and plums in Northern Michigan. 

 These were thought to have been the apple maggot, but we believe 

 they were identical with those which have worked in the cherries 

 of New York and Massachusetts this year. Our correspondents 

 report that thus far this year they have found no indications of the 

 maggots in their plums or prunes. It would not be surprising to find 

 the maggots working in these fruits, which are oftentimes grown 

 nearby, as they are not very dissimilar in their nature to the cherry. 

 Thus growers of plums and prunes, as well as of cherries, should 

 familiarize themselves with this serious menace to their business. 

 Should anyone find maggots or " worms " of any kind in plums or 

 prunes, we would like to be notified of the fact at once.
