THE PICKLED FRUIT FLY— DROSOPHILA 

 AMPELOPHILA, Loew. 



BY G. J. BOWLES, MONTREAL. 



In August, 1879, I met with a small Dipterous fly, Drosophila 

 ampelop/iila Loew, in considerable numbers, and as the subject is of 

 interest to entomologists, I give the result of my observations. I have to

thank Professor Hagen, of Cambridge, for the determination of the species 

 and other information, and also Professor Lintner, of Albany, for a copy 

 of his article in the "Country Gentleman" of ist Jan'y, 1880, on this 

 insect, and from which I have largely drawn. 



With regard to the genus, Professor Lintner says : " Twenty-five North 

 American species of Drosophila are catalogued, which have all, with the 

 exception of three species common to Europe and America, been 

 described by Dr. Loew, the distinguished Prussian Dipterist, and Mr. 

 Walker, of the British Museum. They have not been studied by our 

 American entomologists, and consequently nothing is known of their 

 habits. I find no reference to a single determined species by any of our 

 writers." In the "American Naturalist," vol. 2, page 641, an unknown 

 species of Drosophila is noticed as infesting apples, preferring the earlier 

 varieties. The larvae penetrate the interior of the apple in every direction, 

 and if there are several working together, render it quite unfit for use.
