THE EEPOET OF THE 



No. 36 



to be free from this pest. It is common in the State of Washington and is gradu- 

 ally extending up the Okanagan Valley in the State of Washington. It can only 

 be a question of time that this pest will be found to occur in the orchards of British 

 Columbia, particularly in the Okanagan. We cannot hope for immunity from this 

 pest for all time, consequently from now on the growers in the lower portion of the 

 British Columbia Okanagan Valley will have to keep a sharp lookout for its appear- 

 ance, and when and where it does appear to subject it to immediate remedial 



measures.

The Codling Moth is an insect of the same nature which also is gradually 

 extending up the Valley of the Okanagan. It is closer to the British Columbia line 

 than the San Jose Scale, but as yet it is not reported in the British Columhia 

 territory of that district. Mr. W. H. Brittain, however, found an isolated centre 

 of infestation at Armstrong, a point north of the Okanagan Lake, this summer. 

 Mr. Thos. Cunningham, the Provincial Inspector of Fruit Pests, promptly dealt 

 with it by collecting all the apples in the locality and boiling them in a large vat. 

 This action is to be highly commended as it delays as much as possible the day of 

 general infestation in the Province. 



There seems little doubt, however, that the day is not very far distant when 

 the Codling Moth, like the San Jose Scale, will be present in the British Columbia 

 orchards, and it may reasonably be first expected in the Okanagan, for as soon 

 as the young orchards in the Okanagan A^alley south of the British Columbia 

 border line come into bearing, their infestation is merely a question of time, and 

 this in due course leads to the bearing orchard land in the southern portion of the 

 British Columbia Okanagan District. The Okanagan Valley lying east of the 

 Cascade Range is the channel along which the prevailing winds travel and the birds 

 migrate. 



In my brief stay in the Okanagan I found the orchard mites Bryohia and 

 Tetranychus of economic importance. They are present also in the Lower Eraser 

 Valley, but the dry climate of the interior seems to be more favarohle to the growth 

 and reproduction.
