"Notwithstanding all this, insects come in from Europe so we promulgated 

 the "Plant Quarantine Act Z7'\ the law which caused all the trouble in 1918 lest 

 we exclude every plant from abroad. It has developed on this side the nursery stock 

 industry to a large extent and we do not have to go outside for anything but 

 absolutely necessary stock which we allow to enter so long as it does so through 

 the agency of the Department of Agriculture and its safe-guard. In this way we 

 are becoming independent of other countries and we are not risking the importa- 

 tion of foreign insect pests. 



Friday, the 7th. Mr. W. Lochhead, Macdonald College, gave an interesting 

 address to the meeting on "Hopkins' Bioclimatic Law''. Mr. Winn, Montreal, 

 whose address was titled '"On the Wings of the Wind", delivered a splendid 

 address on butterflies, then came Mr. Xorman Criddle. Dominion Entomological 

 Laboratory, Treesbank, Man., with his favorite canvas: "Locusts in Manitoba 

 with special reference to the ourbreak in I9I9." 



Mr. Brittain, Truro, gave a very interesting address: "Symposium on the 

 Cabbage Root Maggot and its Control in 1919." (Refer to the 9th report of the 

 Society, page 31). The insect (Phorbia brassicae) lays its eggs near the stem of 

 the cabbage, on the soil. Worms go down into the soil and attack the roots of 

 the plant which wilts and often dies. Mr. Brittain said that, as a means of 

 control, the tarred paper, placed about the stem, close to the soil gave good results. 

 But, by his own experiments, he contends, and this is affirmed by many of the 

 entomologists present, that to kill the insect it is quite sufficient to sow along the 

 row of cabbages, some clay mixed with creosote. This mixture would not cost 

 more than 5 cents per 100 pounds. 



Many other addresses were also given: Mr. F. J. A. Morris: "Life-History 

 of a Hobby-Horse"; Mr. E. H. Strickland, Entomological Branch, Ottawa: 

 "Present Status of Pests of Canadian Flour Mills"; Mr. Hudson, Dominion 

 Entomological Laboratory, Strathroy. Ont. ; "Our common June Beetles" ; Mr. 

 Downes, Victoria, B. C. : "Control of the Strawberry Root Weevil" ; Mr. Ross, 

 Vineland Station. Ont.: "The Strawberry Weevil"; Mr. Arthur Gibson, Ottawa: 

 "Borers in Corn and other Field and Garden Plants which have been or may be 

 mistaken for the European Corn Borer."
