Cotton aphids were generally prevalent in the eastern part of the Cotton 
Belt, after treatment for "boll weevil. 
General infestation hy the fall webworm was reported from the New England 
States southward to Florida/ and from the East Central States southward to 
Mississippi. 
Severe damage hy the elm leaf Beetle was reported from the eastern part of 
Massachusetts through Connecticut into southeastern’ New York. It was also preva- 
lent in Pennsylvania, Virginia, and Ohio. 
General damage hy the locust leaf miner was reported from Massachusetts 
southward into Pennsylvania, Maryland, Virginia, and Mississippi. 
Large areas of maples were Being defoliated By the green-striped maple 
worm from Vermont and Massachusetts and across Michigan to Minnesota* 
Rather heavy infestations of screwworms wore reported from Georgia and 
Florida. 
THE MORE IMPORTANT ENTOMOLOGICAL FEATURES 
IN CANADA FOR JULY AND AUGUST 
The grasshopper outbreak in the Prairie Provinces was reduced materially 
By a vtfidespread and i r, ell-organized poisoning campaign; however, the results of 
this work ??ere offset to some extent in certain areas By grasshopper migrations. 
In Manitoba flights of immigrant grasshoppers resulted in increased infestations 
and damage in south-central and, to some extent, in west-central districts. Wheat 
and late oats and Bafley were seriously affected. Heavy losses occurred in an 
area 15-25 miles wide along the international Boundary from Morden to Boissevain. 
Hot, dry weather in August was favourable for oviposit ion. In Saskatchewan there 
were flights of grasshoppers in many localities, But these were largely finished 
By August 10. Counts of dropping of heads of grain By grasshoppers indicate 
that losses for southeast Saskatchewan average J>0 percent for oats and Barley, 
with wheat averaging IS- percent loss south of Moose Mountain, and 8-percent loss 
north to the Qu’Appelle Valley. In Alberta grasshopper migrations were confined 
to the southeastern part of the Province, where extensive losses to late crops 
occurred. 
Blister Beetles are prevalent in the gras shopper- infos ted areas of the 
Prairie Provinces, causing damage to crops, weeds, and ornamental hedges. 
The wheat stem sawfly infestation appeared to Be materially greater than 
that of last year in Saskatchewan. Both in this Province and in southern Alberta, 
practically the entire plains area was infested and the species caused important 
damage to wheat. Severe— to— light infestations of the eastern wheat stem sawfly 
(C_e^rus_ py gmaeus L, ) were found in many wheat-growing areas of Ontario. 
Heavy infestations of Say*s stink Bug occurred in many localities in 
Alberta, from Calgary and the Red Deer River, south to the international Boundary. 
From 10- to 50-percent damage was expected in many grain fields.
