THE MOBE IMPORTANT ENTOMOLOGICAL FEATURES 
IN CANADA ECa MY AH) JUNE 1935 
Cool, moist weather in the Prairie Provinces during May delayed the 
hatching of grasshopper eggs. The earliest hatching of the lesser nigra- 
tory grasshopper and the two-striped grasshopper in Manitoba and of the 
lesser migratory grasshopper in Saskatchewan commenced about the end of the 
third week in Hay. Hatching of the roadside grasshopper in these two 
provinces started at the end of May* Up to the niddle of June general cool, 
moist weather further delayed development, damage to crops was slight, aid 
poisoning operations were limited. In Alberta, grasshoppers were reported 
just beginning to hatch in the first week of June and by mid-June they were 
abundant in snly a few localities and had ce.used no damage. By June 25, 
light damage to crops was becoming evident in some localities in the three 
provinces, but was being held in check by poisoning. The grasshoppers are 
still a serious potential danger if the weather turns hot and dry, but the 
farmers are well organized to combat them. Hatching of the roadside grass- 
hopper in the Kamloops district of Br it i si 1 . Columbia started on May 10 and 
was 75 percent complete by the end of May. 
The pale western cutworm, which has been in outbrerk form over much of 
southern and central Alberta and Saskatchewan during the past several years, 
is again active in many sections, causing quite severe damage to spring 
wheat, particularly in the drier areas of the two provinces. 
Cutworms of various species are unusually prevalent end abundant in 
southern Quebec and Ontario and are causing materiel damage, particularly to 
garden and truck crops. 
Injury by wireworms is very general and unusually serious in Saskatche- 
wan ^specially in districts of medium end light soils. These insects are 
also generally abundant in southern Alberta, causing losses to grain and con. 
Some damage to corn is occurring locally in southern Manitoba. Injury to 
tobacco crops by wireworms has been reported from Ontario, 
Extensive and heavy flights of June beetles occurred in Ontario. The 
beetles caused much injury to the foliage of forest aid shade trees and 
ornamentals. 
Sod webworms are damaging spring grains and pastures in sections of 
southern Ontario. 
Severe Infestations of flea beetles have been reported 03; cruciferous 
crops in parts of southern British Columbia. 
A very low winter mortality of the codling moth is indicated in souther: 
Ontario and with favorable weather conditions the species will probably be an 
important pest this season. Emergence of adults began in the ITiagara district 
on May 25.
