The Colorado potato beetle, Leptinotarsa decemlineata Say, was 
about normal in eastern Canada, during 1929, and less abundant and 
destructive than usual throughout the rVest. In British Columbia 
it occurs only in the extreme southeastern corner of the Province. 
Ihe dry season of 1929 engendered increased crop damage by the 
wheat stem sawfly, Cephus cinctus Start., in sections of the Prairie 
Provinces. The loss to wheat in Saskatchewan in 1929, due to the 
sawfly, was estimated at five and one-half million dollars. The area 
of greatest damage occurred over the south-central part of the Province. 
The sawfly also caused noticeable damage in western Manitoba, and in 
certain localized areas in Alberta. Given favorable weather conditions 
a further increase of the insect in 1930 is anticipated. 
An infestation of the pea weevil, Mylabri s pisorum L., was dis- 
covered for the first time on Vancouver Island, British Columbia, late 
in 1929. Efforts are being made to eradicate the insect which so far 
has not been a pest in the Province. 
Slight infestations of the Mexican .bean beetle, Epilachna corrupta 
Muls,. , were found in three localities in southern Ontario during 1929. 
This species was first discovered in Ontario, in 1927, but the original 
infestations disappeared, and it appears extremely likely that climatic 
conditions will prevent the insect from becoming a pest in Canada. 
During 1929 the plum curculio, Conotrachelus nenuphar Host., was 
a serious pest in fruit-growing sections of eastern C a nada. The apple 
curculio, Tachypterellus quadrigibbus Say, was particularly abundant 
in orchards of southern Quebec, and occurred for the first time as a 
fruit pest in British Columbia, causing severe damage to pears in the 
Salmon Arm district. 
The codling moth, Carpocapsa pomonella L. , appeared to be less 
than normally abundant in eastern sections of Canada. In the '.Test, 
this species is increasing in the Okanagan Valley and on Vancouver 
Island, British Columbia. 
The oriental peach moth, Laspeyresia raolesta Busck, increased 
markedly in southern Ontario and caused serious loss in the Niagara 
district, particularly east of St. Catherines. 
Budmoths were less abundant in Nova Scotia orchards than for 
some years past, but appear to be on the increase in southern sections 
of New Brunswick, Quebec, and Ontario. 
The apple and thorn skeletonizer, Hemerophila pari ana Clerck, 
was recorded for the first time in Ontario, during 1929, in neglected 
apple orchards of the Niagara peninsula. 
The oyster-shell scale, Lepidosaphes ulmj L. , appears to be on 
the increase in sections of New Brunswick and southern Ontario, and is
