8 B. C. ENTOMOLOGICAL PROCEEDINGS, 1912. 



account of these galls. I don't know whether very many of these insects 

 have been described. 



During the past season we have had the usual complement of Green 

 and Wooly Aphis, but I don't think it has been larger than other years — 

 certainly the Green Aphis has not. I have confined my remarks almost 

 entirely to insects doing damage to orchard and other crops, as they have 

 come more especially under my own observation. I should like to give 

 you a list of captures of Lepodoptera, but as this paper is already too 

 long, I shall refrain. 



Tom Wilson,

Vancouver. 



Mr. Treherne — Mr. Gibson of Ottawa wrote to me recently and 

 mentioned the fact that M, erosa was a variety of "disstria." In connec- 

 tion with the Root Maggots in relation to the market gardening industry 

 of the Lower Fraser Valley, I noted that the great majority of the 

 enquiries at the Agassiz Experimental Farm were relative to these insects. 

 I invariably replied giving the thin tarred felt paper discs and the 

 Carbolic Emulsion remedies as having been the most effective in the 

 matter of control. Has any one experience in this country with these 

 remedies ? 



Mr. Wilson^ — I can certainly recall instances where the Carbolic 

 Emulsion has given the gardeners in the Fraser Valley very satisfactory 

 results. One grower saved 90 fo to 9Sfo of his crop a year or so ago by 

 using this emulsion, much to his satisfaction. Previously his crops had 

 been failures. 



Mr. Brittain — Fresh pryethrum has also been effective. 



Mr. Bush — The tarred paper discs are thoroughly effective. 

 Usually this remedy is only advocated for small areas, but after all it is 

 not such a big job over a larger area. 



Mr. Lyne — Is there any merit in puddling the roots in a sulphur 

 and mud bath previous to transplanting? 



Mr. Wilson — That method is of very little use. The eggs of the 

 fly are laid after the plant is in the ground. 



Mr. Lyne — But the sulphur might be objectionable. 



Mr. Wilson — Its aroma is not sufficiently strong. 



Mr. Bush — That is why the tarred discs are so effective. They 

 throw off quite a considerable odor when fresh and thus affect the fly. 



Mr. Wilson — -Discs cannot be used with satisfaction for radishes 

 or carrots.
