AGRICULTURAL EXPERIMENT STATION. 195 



the past two seasons from various parts of the State and his 

 observations show that the pest is on the increase, becoming 

 gradually more widely distributed, doing greater damage where it 

 occurs and constantly extending its depredations to new varieties 

 and new orchards. 



Through correspondence, personal observation, the examination 

 of many varieties of fruit from many localities of the State, and 

 through questions sent to fruit growers by the St. Pom. Soc, we 

 glean, that the pest does the most damage in the western part 

 of the State, and is widely distributed in Oxford, Lincoln, Somer- 

 set, Franklin, Androscoggin, Kennebec, Cumberland, Knox, 

 Waldo, Sagadahoc and York counties. 



The writer has found it in the Penobscot Valley at Stillwater, 

 Veazie and Bangor, and the towns of Charleston and Corinth, 

 in Penobscot County and at Bucksport in Hancock County. In 

 the answers to the Pom. Soc. questions it is reported from forty- 

 four localities in the State. We have no knowledge of its occur- 

 rence in Piscataquis and Washington counties. 



Mr. W. P. Gerrard, of Caribou, Me., writes us that apples 

 from Plymouth, Levant, Garland, Corinth and Dexter and other 

 towns in Penobscot County, sold in Aroostook, are of len badly 

 bored by maggots, but he has not seen it in Aroostook grown 

 apples. 



Introduction. 



Since the introduction of the Apple Maggot in Maine, eight or 

 ten years ago, it has done enough damage each year to attract the 

 attention of fruit growers. It has been considered in the Reports 

 of the State Pomological Society almost every year for the last 

 eight. Accounts of its ravages have frequently appeared in the 

 public prints. During the last four years the writer has received 

 many letters regarding it. 



Its ravages have gradually increased. P^ach year it has 

 extended its depredations further, until it is now nearly State wide 

 in its distribution. It has gradually spread from variety to variety 

 until a large per cent, of the varieties of apples grown in Maine 

 are known to be affected by it. 



Its distribution is so wide and its annual depredations so great, 

 that it seriously threatens the fruit interests of the State and 

 therefore, a consideration of its life history is a matter of State 

 importance.
