70 B. C. ENTOMOLOGICAL PROCEEDINGS, 1912. 



became infected, thus conveying the infection to the orchard where we 

 discovered the larvae. I made diligent enquiry on this point and found 

 that a case of trees had been delivered in the adjoining orchard early 

 last spring. The nursery stock was taken out and planted, but the case 

 was allowed to remain for some months. I believe that probably the 

 larvae transformed early in the month of May and found the conditions 

 just right, with food already prepared. 



It will be asked how can we guard against a repetition of such 

 infection ? My plan is to have a chamber constructed in the new 

 Fumigating Station which is about to be built, in which cases containing 

 nursery stock and the packing used shall be run into this chamber and 

 steamed. This will eliminate all possible danger of carrying infection 

 over in the case or packing. 



I may add that the orchards in question will be carefully sprayed 

 with Arsenate of Lead, not once nor twice, but three times during the 

 coming season, at the rate of three pounds of Arsenate of Lead to the 

 barrel of water. The spraying will be done by my own staff, as we do 

 not intend to take any chances in dealing with this insidious pest. It 

 goes without saying that it will be impossible for the Government to 

 continue this system of purchasing fruit. The expense would be too 

 great ; besides there might be cases of the introduction of the pest all 

 along the Boundary Line where thorough inspection would not always 

 be available. The only rational and business method of protecting our- 

 selves is to rigidly exclude the importation of fruit from countries 

 known to be hopelessly infected with the Codling Moth. 



We had another slight outbreak this season at a place named Rut- 

 land, adjacent to Kelowna. This was different in kind from Armstrong. 

 The infection was not introduced in fruit nor yet in nursery stock cases, 

 but was traced to baggage and household effects that had been stored 

 in a fruit cellar in a section of Ontario, pending the removal of the 

 owner to British Columbia. The cocoons were undoubtedly conveyed 

 in this household stuff. The owner innocently conveyed the infection 

 from his farm house to the orchard, which he had recently purchased at 

 Rutland. 



This involves another problem which will be difficult to deal with. 

 The question arises what shall be done to prevent infected baggage and 

 household effects from coming into this Province? It is a difBcult 

 matter to deal with, but a remedy must be discovered, for we cannot 

 afford to take the risks of the introduction of the Codling Moth into 

 this fair Province. We shall have to devise some means whereby baggage 

 may be closely inspected on the frontier. This may be an inconvenience
