58 N.S. ENTOMOLOGICAL SOCIETY. 



One fruit grower who lives near Digby, and has had experience with 

 the insect in the New England States, says that the insect has been on 

 the increase in that neighborhood ever since he first found it in his or- 

 chard eleven years ago. At Woodstock, the owners of the orchards claim- 

 ed to have first noticed the work of the maggot about six years ago. Sev- 

 eral fruit men near Middleton, who were also accustomed to the insect 

 in the United States, say that it was quite serious in that district nine 

 years ago, but that it has been on the decrease since that time. At Wind- 

 sor the insect seems to have only been noticed these last three years, but 

 it must have been present many years before that to have reached the 

 present state of distribution in that county. 



Thus the evidence is rather conflicting, with an increase in one sec- 

 tion and a decrease in others. This means that a watch will have to be 

 kept upon the insect for some few years to determine whether there is a 

 serious danger to the province. 



Natural Enemies. 



There is a great mortality among the eggs, larvae and pupae this 

 being due to disease, parasitism and to predatory insects. 



There is no doubt that pupae lying exposed in the surface of the 

 ground would soon be picked up by either birds or insects, such as the 

 ground beetles and ants.

In 1914 Mr. W. C. Woods, of Orono, Maine, reared for the first time, 

 from pupae of the apple maggot, a parasite — Biosteres rhagoletis, Rich- 

 mond (Braconidae) — but in this account he stated he had not seen the 

 insect at work. This insect the writer found near Digby in the past
