The wheat-stern sawfly is fairly abundant throughout southern Alberta, 
and general damage is expected. Injury by this species is gene: 11 severe 
in the infested areas of Saskatchewan, where it was accentuated o:j uneven 
ripening and hot weather, particularly in districts where the crop was not 
badly rusted. Light damage has been reported in Manitoba, but where the 
wheat is heavily rusted the larvae are starving and many are dying. 
The sugar beet root maggot, which was first found causing damage to 
late-sown beets in the Barnwell district of Alberta in 193^ > -~ i3 - z again ap- 
peared in that section. 
Adults of the beet webworm have been extremely numerous throughout 
western Manitoba and Saskatchewan and l'ocally in southern Alberta. 
Heavy flights of moths of the sod webworm ( Orambus trisectus Walk.) 
occurred throughout southern Ontario. The larvae of this species had 
attacked pasture fields, corn, tobacco, and other crops. There was also 
general and widespread injure to lawns and golf courses by sod webworms in 
this section. 
An unusually severe outbreak of the pea aphid developed in sections 
of Quebec and Ontario. Damage was less serious than was anticipated, prob- 
ably as a result of the onset of weather conditions unfavourable to the 
aphids. 
The European earwig appeared in exceedingly large numbers in the 
infested areas of southwestern British Columbia, and is proving destructive 
to garden crops in urban areas. 
The black cherry aphid again appeared in outbreak form on sweet 
cherry trees, in the Niagara district of Ontario. 
Injury by the codling moth in the Niagara district is much lesc se- 
vere than last year. The species is in evidence in some sections of the 
Annapolis Valley, Nova Scotia. 
First-generation adults of the oriental fruit moth were found in all 
districts of the Niagara Peninsula, but were in smaller numbers than in 
former years. The species is much less abundant than in 193^ an< i injury 
is slight so far. 
The gray-banded leaf roller is decreasing the apple crop prospects 
somewhat, in the Annapolis Valley, Nova Scotia. 
As usual, the rose chafer appeared in outbreak form in various sandy 
sections of southern Ontario. 
Adults of the grape leaf hopper came through the winter in immense 
numbers in many vineyards in the Niagara district. Injury by these insects 
is severe in unsprayed and poorly sprayed vineyards.
