A NOTE ON RHAGOLETIS POMONELLA IN BLUEBERRIESi 



By William C. Woods 



In the spring of 1913 the attention of the Maine Agricultural Experi- 

 ment Station was called to a certain maggot infesting the blueberries 

 in Washington County; and, accordingly, at the suggestion of Dr. 

 Edith M. Patch, the writer made a few observations on this insect 

 during the summer. Although the work was merely of a preliminary 

 character, the adult was reared, and it seems possible that a brief 

 statement of the situation may be of interest. When bred, the maggot 

 proved to be Rhagoletis pofnonella Walsh. This appears to be the 

 first record from the blueberry, although at least twice it has been 

 reported as bred from the huckleberry, once by Doctor Britton in 

 1906 (Fifth Report State Entomologist of Connecticut, 1905, p. 260), 

 and again in 1910 by Doctor Smith (Report New Jersey State Museum 

 for 1909, p. 802). 



Washington County, which includes a considerable territory in 

 southeastern Maine, is the principal home of the blueberry industry 

 in the state. Roughly speaking, there is a large area of about 250,000 

 acres in this county naturally unforested, known as the "barrens," 

 which has grown up almost entirely with blueberries. Three of the 

 species, Vaccinium pennsylvanicum, V. canadense, and V. vacillans, 

 were to be found attacked by the maggot during 1913. The plains 

 are privately owned, but during the berry season, for a moderate 

 rental, pickers are granted the right to gather the berries, most of 

 which are sold to one or another of the eleven canneries located in the 

 state. 



July 30, when the berries were just beginning to ripen, was the 

 first date on which the plains were visited. No maggots were in 

 evidence, but six adult Trypetids were caught hovering around the 

 berries. These flies resembled the apple maggot exactly, except that
