A&xilt moths of the corn ear worn have been reported as far r.ore abundant 
than for several years at points in- southern Ontario' and southern Quebec. 
Heavy infestations of the larvae also were noted in sections of these Provinces 
and in southern Manitoba, and Light to moderate local infestations in Sas- 
katchewan and Alberta. 
Heavy local outbreaks of aphids occurred on cruciferous crop's in southern 
sections of Ontario, Alberta., and Vancouver Island, British Colunbia. Aphids 
of several species have been extremely abundant on -any kinds .'of plants in 
the Prairie Provinces. Infestation and daaage varied considerably. The apple 
aphid has caused damage in apple orchards in certain sections of "astern 
Canada and in British Columbia. 
Some losses to wheat were caused by the wheat sten sawfly in sections 
of the Prairie Provinces. In Saskatchewan these losses apparently were, some- 
what larger than average, particularly in heavy soils of drier areas. In 
the Red River Valley, Manitoba, the wheat stem maggot caused losses ranging 
from 5 to 15 percent. 
A very general infestation of the common red spider mite in southern 
Alberta resulted in considerable damage to shade trees, garden truck, and bush- 
fruits. This species was a serious pest of small fruits in Ontario and local- 
ly in. Manitoba. The spruce mite was again very prevalent throughout the 
Prairie Provinces. Mites of several species, were troublesome pests of apple, 
plum, and pear in parts of the orchard areas of Ontario and British Columbia. 
There has been a general increase in the codling moth infestation in 
Ontario and southern Quebec. The species was exceptionally abundant in the 
warmer districts of Ontario, where it caused serious damage. 
The gray -banded leaf roller is a serious pest in apple orchards of Nova 
Scotia. 
The oriental fruit moth infestation in the Niagara Peninsula, Ontario, 
was about the same as in 1333 . The species survived winter temperatures as 
low as 23° below zero. 
Grape leafhoppers were exceptionally abundant in unsprayed or poorly 
sprayed vineyards in southern Ontario, where they caused much damage. 
The outbreak of the 'European spruce sawfly continues in the G-aspe Peninsula, 
Quebec, and the larvae have defoliated much of the white spruce over a large 
area. Black spruce is less heavily infested, but defoliation of this species 
also is severe. The sawfly has now been found to bo generally distributed in 
New Brunswick, but up to the present damage in this Province is not severe. 
The hemlock looper has appeared in destructive numbers in parts of Nova 
Scotia and on AntiCosti Island. 
The red-headed pine sawfly is causing serious damage in many localities in 
Ontario and Quebec. 
The satin moth has been reported in the Peace River district of British 
Columbia, east of Rolla.
