Tha nose bot-fly, Gastrophilus vetqrinus Clark, is yearly assuming 
mors impartan&sin the Prairie Provinces and its distribution appears to 
be general* 
The Hessian fly will cause loss in Manitoba it is feared* The area 
of infestat ion will doubtless occur in the territory north of the 
Canadian Pacific Railway line in areas of the greatest rainfall* 
Tla eastern spruce bark-bpetle, Dendroc tonus, p iceanerd a "Kirby, has 
been active in two localities in Canada during the past few years* in 
outbreak of increased proportions is anticipated this year in the Gaspe 
Peninsula, in Quebec Province, due to the last gear's brood concentrating 
on the weakened trees of a large burn. The Porcupine mountain outbreak 
in Saskatchewan almost completely died out last year and is not expected 
to cause any trouble this year* 
The European corn, borer wintered successfully in Ontario, the 
very low mortality of 3 per cent being recorded in overwintering experiments

HESSIAN FLY ( Phvtothaga destructor Say) 
Illinois T7. p. Flint (April 30): Adults of the Hessian fly have 
not yet been found in the fields* 
Indiana J* J • Davis (April 30): The Hessian fly is not abundant- 
Sowing at the right time has doubtless been effective in 
keeping down the Hessian fly in the northern half of Indiana. 
A late wave last fall is responsible for some fly infestation 
in southern Indiana. In Adams County in the northeastern 
part of the State we examined last fall (November 22) several 
fields sowed on different dates, scattered over the county* 
The results of these counts were as follows:
