corded from that section. Towards the end- of June, damage was over for the sea- 
son, with the most extensive crop losses in the Province in a decade. Heavy 
damage was also done locally in Saskatchewan,, Another species, the army cutworm, 
was more abundant in southern Alberta than at any time since 1928 on vegetation 
of all kinds, but losses were generally light. Many of the larvae were destroyed 
by disease. Hatching of eggs of the redbacked cutworm, at Saskatoon, Saskat- 
chewan, was complete by April 19 » or about 12 days earlier than 193&* Cutworms 
caused material loss in various localities in this Province, 
Wireworms have been generally destructive in western Saskatchewan, es- 
pecially in areas where crop growth was retarded by drought, soil drifting, and 
frost. In Alberta, approximately 1 percent of the wheat acreage is reported to 
have been destroyed. A recent survey in Manitoba indicated very little damage 
by these insects. Throughout southwestern Ontario wireworms were reported to be 
more numerous, than usual. 
Major flights of June beetles occurred in southern Quebec, late in May and 
locally in southern Ontario.. Third-year white grubs' of this species are common 
in many parts of- Ontario, where severe damage was done In 193&* 
Asparagus beetles were unusually abundant in southern Ontario. In Niagara 
district the greatest injuryto the asparagus crop occurred late in May, 
Mush' damage to young vegetable garden plants was done by the hop flea 
beetle in southern Alberta.

The fruit tree leaf roller is increasing in many sections of the Okanagan

Provinces. 
Outbreaks of tent caterpillars occurred in 'many' parts of Eastern Canada, 
and were particularly severe in sections ,o.f Ontario and Quebec.

Infestations of the fall canker worm were reported in Hew Brunswick, 
southern Ontario, and the Prairie Provinces. It is reported that the shelter 
belts on at least 10,000 square miles of land in central Saskatchewan are very 
severely infested by this species. ".". •
