CANADA. 



In Canada Dr. Hewitt, Dominion entomologist, writes that 

 the apple maggot is common and injurious in certain sections in 

 Ontario, Quebec and New Brunswick, and is known to be at work 

 in Nova Scotia. The occurrence of the pest in any district is 

 subject to considerable fluctuation from year to year. 



In Ontario Mr. Lawson Caesar has found the apple maggot in 

 sixteen counties, ranging from Dundas, about twenty miles from 

 Ottawa on the east, to Lambton County on Lake Huron. Only 

 a small percentage of the orchards in any of these is infested and 

 in some the insect has been found only in villages or towns. He 

 thinks that further investigation will probably show that it 

 occurs to a very limited extent in several other counties. The 

 pest is worst in the district situated along the northeast part of 

 Lake Ontario. 



Professor Turney writes that in New Brunswick their records 

 show the presence of the maggot in certain orchards at Woodstock, 

 in Carleton County. 



• In Nova Scotia, Mr. William H. Brittain writes that the species 

 is quite prevalent in parts of Digby County, in the southwestern 

 part of the province. Specimens of infested fruit have been 

 noted also in Yarmouth County, and it is probable that the pest 

 has a wider distribution throughout the province than is at 

 present known. 



THE UNITED STATES. 



The situation in Maine is summarized by Dr. Patch in the 

 statement that the insect is the worst insect pest attacking the 

 fruit of apple in the state, and that its range covers the whole 

 apple growing territory. 



A discussion of New Hampshire will be found later in this 

 bulletin. 



In Vermont Professor Cummings Avrites that the insect has 

 caused much harm quite generally over the state, more particu- 

 larly in orchards where sweet or semi-sweet apples occur. Other 

 varieties are sometimes infested. 



Dr. Fernald states that the maggot appears to be generally 

 distributed over Massachusetts, and at least in some places is 

 extremely abundant.
