OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA TO JUNE 25, I93U 
Tlxe grasshopper outbreak continues to "be of outstanding irportaiice throughout 
the grain-growing areas of the three Prairie Provinces. Hatching of the major 
species began at the end of April in Alberta and early in May in Manitoba ani Sas- 
katchewan, being fron 2 weeks to 1 month earlier than in 1933* Late in May an 
early in June hatching was general and almost complete in. many, sections, and crops 
were damaged severely over wide areas. Unseasonably hot weather and retarded crop 
growth, lue to lack of moisture, greatly increased the extent of the damage. In 
southeastern Saskatchewan important grasshopper migrations started, owing to lade 
of food in the infested fields. General rains and cooler weather daring the first 
half of June caused further germination of seed, better cr^p growth, and lessened 
activity of the insects, and control campaign efforts were much more effective under 
these conditions. In Saskatchewan it is generally accepted that in much of the 
area of very severe infestation, where the soils are light or medium, there would 
have been little or no crop survival after the drought had it not been for the con- 
trol campaign. 
The pale western cutworm began hatching early in the infested areas of Saskat- 
chewan and Alberta Coy April c ?0 in southern Alberta), and by the middle of May the 
infestation was general and damage had started. The Lamage to crops by this spec- 
ies during May was excessive. The insects were checked, however, by rains and cool 
weather in June. In Manitoba . relatively little cutworm damage has been noted. 
In Eastern Canada local cutworm damage, unusually severe in some sections, was re- 
ported in New Brunswick, southern Quebec, and Ontario. 
Some losses from wireworms have occurred in certain localities in southern Al- 
berta, In Saskatchewan wireworms have '.one considerable general damage to crops 
on summer-fallow, especially in medium soils. Seasonal conditions have been gener- 
ally conducive to severe injury by these insects. 
Moderate flights of May or June beetles were noted in southern Quebec, eastern 
Ontario, and locally in southern Ontario during May. The ties caused some 
damage to the foliage of shade trees, raspberry, roses, and her plants. TFhite 
grubs are distinctly reduced in numbers in eastern Ontari . as c impared with la.st 
year, but they are sufficiently abundant to indicate an exceptionally large flight 
of beetles for 1935. ^0 or more grubs per square yard of sod being common. 
Extensive flights of beet webworm moths occurred in various localities in the 
Prairie Provinces during May. In Saskatchewan they were .. rally pr> sent through- 
out at lea-st the central aid southern parts of the province. 
The hop flea beetle is somewhat more abundant than average in localities in 
southern Alberta, attacking radishes, rhubarb, and sugar } ts, and is 1 r is in 
wer Eraser valley, British Columbia, causing local lamage to hops. Crop 
damage "oy the potato flea beetle is severe in sections of Ontario, 1 nd the cabbage 
flea beetle is troublesome on Vancouver Island. 
cal a ' maggot is a. serious pest on untreated plants in southwestern Ontario, 
•ere noted in southern Quebec as more nui in 1 933 • Seed corn maggota 
have damage L truck crops on Vancouver Island. 
Orchards in the Annapolis Valley, Nova Scotia, appear to be unusually f ee from 
insect pests. In the Okanogan Valley, British Columbia, certain fruit pests are 
■ • ■ . n usual. Overwinteri iditions in the Olconagan were very 
favor:-. 1 .; le for hibernating insects*
