infestations "by forest tent caterpillars were occurring over this sane terri-

The elm leaf "beetle was quite prevalent in the New England and Middle 
Atlantic States, with unusual damage in the East Central States and localized 
outbreaks in Idaho and California. 
European elm scale was generally prevalent from New York to Iowa. 
THE MORE IMPORTANT FEATURES IN CANADA 
IN MAY AND JUNE 1936 
The grasshopper outbreak in the Prairie Provinces, which has been wide- 
spread, serious, and menacing since 1930, was greatly reduced during 1935 hy 
weather conditions, natural enemies, and the effects of organized intensive 
control campaigns. Indications this spring point to still further reduction. 
Hatching in Manitoba was slow and irregular and no damage has been observed, 
so far, except in the southwest, where dry conditions caused some trouble 
from grasshoppers. In Saskatchewan hatching began the middle of May, but up 
to the middle of June, the infestation in southern areas was very light and 
no severe damage had been done. The insects were generally abundant west of 
Saskatoon, but damage has been minimized by cool weather, heavy rains, and the 
distribution of poisoned bait. In Alberta slight losses to crops were occurring 
in drier areas late in June, but theeo were being held in check by the poisoning 
campaign. A moderately widespread outbreak of grasshoppers has developed in 
sandy regions of Renfrew and Hastings Counties in eastern Ontario, 
Cutworms of several species v;ere reported to be unusually abundant and 
causing damage to garden, truck, and field crops in parts of every province 
in the Dominion. A resurgence of these insects occurred in many parts of 
Canada in 1935* The pale western cutworm is in serious outbreak form in 
southern Alberta, causing severe losses to grain crops in some areas. Quite 
severe damage was reported also in sections of Saskatchewan. A considerable 
outbreak of the red-backed cutworm was reported through much of the northern 
and east-central part of the Pr.rk Belt in Saskatchewan, with resultant damage 
to field and garden crops. It caused local damage in gardens in southern 
Manitoba. 
'.Vireworms are proving to be the most serious pest of the year in 
medium- and light-soil areas of prairie and open-park sections of Saskatchewan. 
Losses to wheat seeded in summerfallow quite generally ranged from 10 to 50 
percent. Infestations have increased markedly in recent years, particularly 
in idle fields and in districts affected by drought and soil drifting. In-' 
festations are general in many areas of southern Alberta, with damage slight 
to severe. 'Vireworms were reported as destructive to grain and other crops 
locally in southwestern Ontario. 
A major flight of June beetles occurred in southern Quebec and much
