Wireworms caused severe damage to w heat in western Saskatchewan, and 
to sugar beets, locally, in southern Alberta, this spring. Moisture con- 
ditions were favourable to wireworms in the affected areas. 
Moths of the beet webwom have been extremely abundant in Alberta, 
Saskatchewan., and Manitoba, and very heavy and widespread outbreaks of the 
larvae are indicated. Weeds such as lamb's quarters and Russian thistle 
are chiefly subject to attack, but the species is also a pest in gardens. 
A large flight of June beetles ( Phyllophaga anxia Lee.) occurred in 
eastern Ontario, in late May and June, over an area of possibly 1,500 
square miles. Heavy damage to crops by the resultant grubs is considered 
probable in 1933. 
Outbreaks of flea beetles, notably the potato flea beetle, are re- 
ported from southern Ontario affecting potato, tobacco, and other plants. 
Adults of the oriental fruit moth commenced emerging much later than 
in 1931 in the Niagara district, Ontario. The first-brood infestation is 
lighter than it has been in any spring since the species became of economic 
importance as a peach pest in southern Ontario. 
A serious outbreak of grape leafhoppers developed in the Niagara 
fruit district in Ontario. 
The balsam bark louse, Dreyfusia piceae Ratz., continues to spread 
slowly in southern New Brunswick and now extends up the St. John ]£Lver 
Talley a distance of a little more than 50 miles from the coast. This 
insect occurs throughout Nova Scotia, where it is one of the most important 
forest insect pests. 
Heavy infestations of the western willow leaf beetle occurred over 
wide areas in Saskatchewan and Alberta, resulting in severe defoliation of 
poplar and willow in the affected territory. 
In sections of southern Manitoba, several species of deciduous trees 
have been completely or partially defoliated by the fall canker worm. The 
outbreak of this insect in New Brunswick, which was moderate in 1951, has 
intensified somewhat, and much defoliation of elm and basswood has occurred. 
The larch case bearer continues in outbreak form over a large part of 
e:astern Canada and in many sections severely defoliated larch. 
Ticks are reported as unusually abundant in wooded areas in parts of 
Manitoba and Alberta, and sections of British Columbia. Several species 
are involved. In addition to attacking wild and domestic livestock, cases 
were reported from Vancouver Island and coastal districts of British 
Columbia, of ticks attaching themselves to humans.
