becoming a serious pest in the interior of British Columbia. 
Spider mites were prevalent in many parts of Canada, during 1929, 
The European red mite, Paratetranychu s pilosus C. & F., for the first 
time was an important pest in orchards of southern New Brunswick, and 
was abundant and injurious in the Niagara district, Ontario. Red spiders 
also heavily infested small fruits and various other plants in sections 
of Ontario and the Prairie Provinces, and fruit trees in the Okanagan 
Valley, British Columbia. 
An outbreak of spruce budworm, Cacoecia fumiferana Clem., on 
balsam, in the '.7 e stree district, north of the Georgian Bay, Ontario, 
which apparently originated around Meteor Lake, is slowly extending 
westward. The outbreak of this species on Vancouver Island, British 
Columbia, north of Victoria, is subsiding. 
The fir sawfly, Neodiprion abietis Harr. , was found infesting a 
considerable area of balsam forest in the Sault - Ste. M a rie district, 
Ontario, during 1929. An outbreak of this insect in Manitoba has been 
much reduced by parasites. An incipient outbreak of a species of saw- 
fly, of the same genus as the abova, has been discovered affecting jack- 
pine over a considerable area in the Biscotasing district, Ontario. 
Severe local outbreaks of the latter insect also were found in Quebec. 
The satin moth, Stilpnotia salicis L. , which was first recorded 
in Canada at New '.Testminster, British Columbia, in 1920, now occurs 
throughout the Lower Fraser Valley and on the east coast of Vancouver 
Island. 
The European beech bark louse, Cryptococcus fagi Baerns., which 
occurs widely in Prince Edward Island and N va Scotia, is spreading 
northward in eastern New Brunswick from the infested area in Albert 
and »V e stmoreland Counties. It was first discovered in New Brunswick 
in 1927. 
The brown-tail moth, Nygmia phaeorrhoea Don., has been practically 
eliminated from'.'Canada. The only evidence of the pest found since 
1927, in the previously infested areas in the Maritime Provinces, was 
a male moth captured at Fredericton, New 3runswick, in July, 1929. 
Infestations of the gipsy moth, Porthetria dispar L. , discovered 
in southern Quebec in 1924, in Stanstead and St- Johns Counties, appear 
to have been completely stamped out by the vigorous combative measures 
adopted. Extensive scouting, continued in 1929, failed to reveal any 
evidences of the pest.
