Heavy infestations of the fall webworm were reported locally in Uova 
Scotia., Quebec, and southern Ontario. A more general outbreak occurred in 
Manitoba, and severe infestations occurred in various localities in Saskatche- 
wan and Alberta. 
Adults of the European spruce sawfly, in flight during the first week 
of June in central New Brunswick, were several times more numerous than in 
193 1 !-. In the Gaspe Peninsula, Quebec, the infestation continues to be heavy 
and an increase in mortality of the trees is inevitable. The infestation has 
increased considerably in Kamouraska County, Quebec, and some of the trees 
are dying. The species ha.s been found in Cumberland and Pictou Counties, 
Nova Scotia, but does not appear to be present yet in other parts of that 
Province. 
The yellow-headed spruce sawfly caused extensive defoliation of spruce 
in northern Saskatchewan and northern Alberta. Indications are that it will 
eventually become genera.lly distributed throughout the southern portion of 
these Provinces. 
A severe outbreak of the mountain pine bark beetle, affecting lodge- 
pole pine, has ''oeen found in the Kootenay National Park, -British Columbia. 
It is believed that the outbreak has been spreading during the past 5 years. 
Heavy infestations of the satin moth have been reported in a number 
of localities in Prince Edward Island; the Amherst and Springhill districts 
in Uova Scotia; and in Sackville, New Brunswick. The moths were emerging on 
July 13 in Nova Scotia. The species is reported to be comparatively scarce 
over the greater part of the area of infestation in British Columbia. 
Reports of increased abundance of mosquitoes, as compared with previous 
years, have been received from New Brunswick, southern Quebec, sections of 
Ontario, and the Western Provinces. They were noted as extremely abundant 
and annoying throughout the three Prairie Provinces, and were reported to be 
an exceptionally severe pest in the Kamloops area and the Cariboo district 
of 3ritish Columbia.
