July, 1914.] THE APPLE MAGGOT. 23 



In none of the states farther west has the species been observed 

 at work. 



For Ohio Professor Gossard states that but little damage is 

 done by the maggot. An apple is occasionally noted that has 

 been mined by it, and there are sometimes reports that it (pre- 

 sumably this species) has been doing considerable damage in 

 an orchard here and there. 



In Indiana Professor Troop has found the species to some 

 extent. It is not considered such a universal pest as the codling 

 moth and some other species, but in certain seasons and in certain 

 regions or sections of the state it makes itself felt almost every 

 year. 



In Illinois Dr. Forbes writes that he has never seen a specimen 

 of the maggot in the state, or any evidence of its occurrence. 

 It is not represented in the collections of the state. 



South of the Ohio River definite observations of the occurrence 

 of the species are lacking. 



In the southwest the only positive observations are from Ar- 

 kansas. Professor Becker writes that it was once thought that 

 the pest occurred there, but that he could not confirm this from 

 personal observation. A recent letter from Dr. Hinds transmits 

 the information from Professor Walker, formerly horticulturist 

 of the Arkansas Station, that he has seen in the Ozark region, 

 Arkansas, a little of the work of an insect that he takes to be the 

 apple maggot. 



ECONOMIC STATUS IN NEW HAMPSHIRE. 



The economic position of the apple maggot in New Hampshire 

 may be summarized as follows: 



It is one of the important, destructive and persistent apple 

 insects of the state. It is found throughout the state, wherever 

 the apple is grown commercially. It has infested apples more or 

 less in the greater part of these areas for many years. Its 

 damage fluctuates widely from year to year, remaining invariably 

 most persistent in early fruit and showing the widest variation 

 in winter fruit. The general circumstances in the state as 

 regards the condition and care of the ordinary farm orchard 

 and as regards the prevalence of infested wild apples, are exceed-
