THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN 
CANDIDA EOR AUGUST AND SEPTEMBER 
The grasshopper infestation in southwestern Manitoba was augmented "by 
migration flights. In this area crops were cut early to lessen damage, "but late 
crops suffered. An adult survey showed a heavy build-up of the infestation in the 
southern and western margins of the Province, probably largely due to flights. 
Weather conditions were favorable to egg laying, and a heavy infestation is ex- 
pected in 1939. In southeastern Saskatchewan there were general flights of grass- 
hoppers, and tb invasion and loss in the Regina area was serious. Grasshopper 
damage and premature cutting rather generally reduced the production of oats and 
barley, with severe but spotty losses in some districts. Late wheat crops over 
much of the southeastern and south-central aroa suffered heavily from the clipping 
of heads by flying grasshoppers. Oats also were severely attacked, even after 
being stooked. Present prospects- indicate an extension of infestation into areas 
of Saskatchewan not previously infested this season, and a general increase in in- 
tensity in most instances. In southern Alberta there was some increase of grass- 
hopper numbers, as compared With 1937 * and slight losses occurred in late crops. 
Grasshoppers were causing concern in parts of the Nicola Valley, British Columbia. 
The entire Peace River country was also more or less infested. 
The wheat stem sawfly caused damage to wheat in central and southern areas 
of Alberta. Rains in the latter part of August rendered most of the sawfly-cut 
grain a total loss by knocking it flat to the ground. Considerable loss also 
occurred in Saskatchewan, where the damage was heavier than in 1937 » although still 
considerably below the average annual total of the years prior to 1§3^« 
An outbreak of the European earwig was reported for the first time in 
Eastern Canada, at Ayton, Grey County, Ontario. 
The outbreak of the amyorn which occurred during the summer involved, to 
some extent, every Province from Prince Edward Island to Saskatchewan* The out- 
break was locally severe in the three Maritime Provinces, Ontario, and Manitoba. 
In Quebec several counties were involved in a widespread outbreak, which affected 
thousands of acr s of crops. The infestations in Saskatchewan were scattered, 
localized, and of light— to— moderate intensity, but several were in open prairie 
from which no reports were received in previous years. 
A major outbreak of second— year white grubs largely destroyed thousands of 
acres of semipasture, and garden and field crops, in Durham, Ontario, and York 
Counties, Ontario. Important injury to market— garden crops also occurred in the 
Niagara district. In addition, there was much damage to crops by these insects in 
southern Quebec. 
Records of abundance of European corn borer moths and larval establishment 
at the Chatham laboratory, in southwestern Ontario, indicated a tremendous increase 
in infestation during the present season, and it was expected that the borers 
would be more abundant than at any time during the last 10 years. 
Reports of damage to sweet and ensilage corn by the corn ear worm were re- 
ceived from southern New Brunswick, and locally from Quebec, Ontario, Manitoba, and 
Sas kat chewan.
