 thei-efore, as it has 

 not been observed 

 attacking goose- 

 berry bushes in its 

 native State, where 

 they are extensively 

 grown, its apparent 

 abundant presence 

 in the above in- 

 stance must be con- 

 sidered as accident- 

 al, and, further, as all the infested bushes were destroyed, it is hardly 

 likely that it will ever become an important enemy of the fruit grower 

 in British Columbia. 



The Westefn Strawberry Crown-borer (Tyloderma foveolatum, 

 Say). — Injuries by a crown-borer which attacks strawberries in 

 British Columbia in a perfectly similar way to the eastern species 

 Tyloderma fragariœ, Riley, have proved to be by the above named 

 species. (Rep. Exp. Farms, 1897, p. 204.) 



The Apple Maggot {Trypeta pomonella, Walsh). — A most destruc- 

 tive enemy of the apple fruit is the Apple Maggot, which has appeared 

 in Canada in one or two places only (Rep. Exp. Farms, 1896, p. 256), 

 although for many years it has caused great loss to fruit growers in the 

 States of Vermont and Maine, and also in ISTew York, Massachusetts 

 and Connecticut. The life history is well known, having been worked 

 out very completely by Prof. Harvey, of the Maine State Agricultural 

 College. The remedy is comparatively simple but requires great per- 

 sistence. The one that is most relied on by those who have' had most 

 experience, is the prompt destruction of windfalls, so as to prevent the 

 maggots going into the ground when they leave the fruit to complete 

 their transformations. This can be done by keeping pigs, sheep or 

 other stock in the orchard. Prof. Harvey says emphatically '"the 

 gathering of windfalls for the chocking of Tiypeta has been tried 

 and found effectual." Deep spading or ploughing of the ground under 

 the trees and the keeping of poultry in the orchards are very useful, 

 because when the larvœ leave tlie apples to pupate they always remain 

 near the surface of the ground. 



The Currant Maggot {Epoclira Canadensis, Loew.). — The' injuries 

 by the Currant M'aggot in many places on Vancouver Island are so
