THE MORE IMPORTANT RECORDS IN CANADA FOR JULY 1934 
Conditions accompanying the drought have accentuated the grasshopper out- 
break in the Prairie Provinces, particularly in Manitoba and Saskatchewan. 
The winged insects are migrating, but actual crop damage is limited to the 
southern districts. In Manitoba .there is still a shortage of moisture and 
crops have suffered considerably from hot, dry weather, particularly in 
southern and western sections. Large numbers of grasshoppers have reached the 
winged stage and several extensive flights in northerly and easterly directions 
have occurred. In eastern Manitoba, where good control was obtained, poison- 
ing operations ceased early in July, but were continued a few days longer in 
western Manitoba. In Saskatchewan control efforts have succeeded in keeping 
losses from grasshoppers generally low in areas having moisture sufficient 
for a fair crop, but in heavily infested, drier areas, it became necessary to 
cut much of the corn for fodder. General drought and warm weather in mid- 
July tended to increase hopper damage, and the situation is increasingly 
critical in the large southern area where moisture has been below normal 
throughout the season. In much of the central and west-central crop districts 
of Saskatchewan the outbreak is apparently largely under control for this 
season, unless extensive flights occur. Migrations are reported in various 
sections. In Alberta the control campaign has held crop losses from this pest 
to a minimum. A large proportion of the insects were winged by early July and 
by the middle of the month extensive migrations were taking place, with popula- 
tion increases reported from the foothills area. Some local losses were re- 
ported, but in most areas the grasshoppers were under control. 
In SaskatcheY/an the season has been generally conducive to exceptionally 
severe wireworm injury. 
In eastern Ontario a severe local outbreak of white grubs resulted in 
crop damage amounting to many thousands of dollars. Heavy flights of June 
beetles occurred this spring in southern Quebec, causing defoliation of trees 
and shrubs. Local flights were reported in Ontario. 
The caragana beetle is again abundant and destructive to caragana and 
beans in parts of the Prairie Provinces. Infestations of several other 
species of blister beetles have been reported. 
The striped cucumber beetle caused notable damage to untreated cucurbits 
in parts of New Brunswick and Ontario. 
The rose chafer has again been a troublesome pest of garden plants, shrubs, 
and small fruits in sandy sections of southern Ontario. 
Indications are that the codling moth will again cause serious losses in 
some orchards in the Niagara district, Ontario. 
The apple curculio end the plum curculio ere reported to have increased 
in abundance ov-.t previous years in orchard sections of southern Quebec. 
Outbreaks of the rosy apple aphid and the black cherry aphid were reported 
in some orchards of the Niagara district, Ontario. 
Forest tent caterpillars caused conspicuous defoliation of poplars and 
certain other trees in parts of eastern Canada, Saskatchewan, and eastern 
British Columbia. The fall cankerworm defoliated many valuable windbreaks in 
Manitobr and in parts of Saskatchewan.
