Vceux de la Confederation gen^rale des Vignerons. [Resolution passed 

 by the General Confederation of Vinegrowers.] — Rev. Viticulture, 

 Paris, xlvii, no. 1201, 5th July 1917, p. 15. 

 The Administrative Council, in consequence of a resolution passed 

 by the General Confederation of Vine-growers and in view of the repre- 

 sentations of the Departmental Councils that the use of soluble arsenates 

 is no more dangerous to public health than the use of insoluble arsenical 

 salts, requests that the use of the former salts shall be definitely 

 authorised under the same conditions as insoluble arsenical ones and 

 that Article 11 of the decree of 15th September 1916 [see this Review, 

 Ser. A, V, p. 47] shall be modified in this sense. 



La Pyrale et les Traitements arsenicaux. [Sparganothis pilleriana and 

 Arsenical Treatments.] — Progres Agric. Vitic., Montpellier, Ixviii, 

 no. 28, 15th July 1917, pp. 55-56. 



Sparganothis pilleriana has been causing considerable damage in 

 many vineyards, the reason being that the majority of vine-growers 

 have been unable to carry out the winter treatments which destroy 

 the greater part, if not all, of the larvae hidden under the bark. Both 

 labour and coal necessary for the hot spraying have been lacking, 

 while the prohibition of the use of soluble arsenicals has prevented 

 many vine-growers from resorting to arsenical whitewashing. It is 

 hoped that the protest issued by the Confederation of Vine-growers 

 [see above] against this prohibition will be considered in time to carry 

 out the necessary measures during the winter of 1917.

to Wheat and Barley in Sv/eien.—Mthly. Bull. Agric. Intell. & PI.

and 34-42, 1917.] [Received 21st September 1917.] 



The larvae of Contarinia tritici did considerable damage to the 



different varieties of wheat during the summer of 1916. The damage, 



which varied from 5 to 10 per cent, and in exceptional cases amounted 



to 60 per cent, of the yield of grain, was caused by the insect depositing 



its eggs in the flowers of wheat and other cereals immediately after 



they had come into ear. Bearded and beardless varieties were equally 



liable to attack, but the varieties that suffered most were early ones, 



coming into ear from the 27th to the 29th of June, while those that 



came into ear from the 1st to the 3rd July suffered least. The same 



thing was observed in barley fields in other parts of Sweden, and does 



not imply a higher specific resistance on the part of the late varieties, 



but merely points to the fact that the females of this Cecidomyid are 



more numerous in June ; in other conditions of temperature and 



moisture precisely the opposite state of affairs might occur.

The larvae of Coeliodes fidiginosus attack poppy plantations by 

 boring into the upper part of the roots, causing them to tm^n black
