and feeding on the soft pith ; in the autumn, the larvae pass into the 

 roots, where they pupate and winter. Remedies recommended inchide 

 removing and burning the damaged plants and the rubbish, powdering 

 coal-dust on the plants in May, which drives the larvae from them, 

 watering the soil with a weak solution of potassium permanganate, 

 and in autumn, with carbol-enudsion in order to destroy the larvae 

 in the roots. Rotation of crops is also indicated.

Gardeners' Chron., London, Ivi, 1457, 28th November 1914, p. 357. 



The author recommends the use of gas tar as an efficient remedy for 

 mealy bug [Pseudococcus citri] [see this Review, Ser. A, ii, p. 101].

Chortophila brassicae attacks cauliflowers even to a greater exter.t 

 than it does ordinary cabbages. In many cases in Petrograd, the 

 cultivation of cauliflowers has been made impossible by these larvae, 

 which usually appear in the second year, especially when the soil has 

 been manured with rotten dung.

This note, republished from " The Bulletins of the Simferopol 

 Branch of the Imperial Russian Society of Horticulture," refers to a 

 control measure against Gnjllotalpa recommended by a Swiss horti- 

 culturist. The remedy consists in placing calcium carbide in the 

 burrows of this pest, and when the earth has then been trodden down, 

 the carbide, under the influence of moisture, produces acetylene gas, 

 which destroys the insects.

control of insects in orchards.] — «CaflOBOfl"b.» — [The Fruit- 

 Groiver], Rostov-on-Don, no. 11, November 1914, pp. 815-816. 



The importance of a knowledge of the identity of various pests of 

 fruit trees to owners of orchards, is emphasised. 



In order to ascertain whether trees are infested with species of 

 Psylla, cut branches should be examined with a lens for the presence 

 of the minute eggs of this pest, which resemble linseed. Against 

 these insects, spraying with tobacco extract (i lb. to 30 lb. ot water) 

 and fumigation with tobacco dust are recommended.
