 Agric. Gaz. Canada, Ottawa, i, no. 10, October 1914, pp. 817-818. 



The green apple aphis, Aphis jpomi, and the mealy plum aphis 

 Hyalopterus arundinis, F., were unusually prevalent in some coast 

 sections. Control by the use of Black Leaf 40, with or without soap, 

 was in most cases successful when properly handled. The bud moth, 

 Eticosma ocellana, on apples and cherries, was especially prevalent 

 in the coast sections and was controlled by lead arsenate. A climbing 

 cutworm seriously attacked clover and apple trees. On the latter, 

 sticky fly-paper bands were used on the trunk and the foliage was 

 sprayed with lead arsenate. The cabbage root maggot, Chortophila 

 brassicae, was abundant on cruciferous crops and the damage was 

 aggravated by the unusually dry weather. The tar-paper disk method 

 was exceptionally efficient.

Nearly every seed head of Arctium minus in the Ottawa district 

 is said to harbour one or more larvae of Metzneria lappella, L., during 

 autumn and winter. M. lappella, a native of Europe and Asia, was 

 discovered in Canada, at Levis, Quebec, in September 1898, and is 

 supposed to have been introduced there in the burs of A. minus, 

 contained in fodder. It has since spread considerably throughout 

 Quebec and Ontario and is abundant at Toronto, where it has been 

 observed since 1904. 



Parasol Ants. — Bull. Dept. Agric. Trinidad d Tobago, Port-of-Spain, 

 xiii, no. 83, August-October 1914, p. 280. 



The Governor of Trinidad and Tobago has declared the parasol ant, 

 Atta sp., to be a pest within the meaning of the Plant Protection 

 Ordinance of 1911. An order can now be served on any one having 

 nests of this pest on his land, compelUng him to destroy them. 



La destruction des noix du coton par le feu. [The destruction of 

 cotton bolls by fire.] — Bull. Union des Agriculteurs d'Egypte, 

 Cairo, xii, no. 108, July-October 1914, pp. 247-248. 



On the 5th October, the inspectors of the Ministry of Agriculture, 

 now responsible for cotton worm control in Egypt, were instructed 

 to enforce the Khedivial decree relating to the removal of the bolls 

 before the cotton plants were uprooted and their subsequent des- 

 truction by fire. The bolls must be removed 15 days before the three 

 dates, 15th October, 15th December, and 31st December, fixed as 

 the time limits for the uprooting, the variation of the dates being 

 according to regions.
