Ill 



experiment in attracting the imagines with molasses and yeast was 

 made, which, although not quite successful owing to the rainy weather, 

 demonstrated that the moths find this substance attractive. In 

 the course of the discussion on this paper, V. G. Averin recorded the 

 occurrence of this pest in Charkov on fields of summer-sown wheat, 

 barley and oats over an area of 39,000 acres. In some cases where the 

 fields were re-sown, they were again destroyed. He recommended 

 mowing the attacked crops and burning them, or, when the number of 

 caterpillars was not great, feeding cattle with the crop. S. A. 

 Mokrzecki reviewed the outbreaks of this pest, dating from that 

 observed by Lindeman in 1882, in the province of Kuban. He had 

 bred 5 species of parasites of this pest, the most important being a 

 species of Trichogramma, and had also obtained a secondary parasite, 

 Anthrax hottentotus, L. {flavus, Meig.). L. D. Moritz reported that in 

 1911 there was an outbreak of this pest in the government of Orel, on 

 winter-sown rye. G. S. Sudeikin referred to the damage caused by it 

 in the province of the Don, in the government of Voronezh, where some 

 5 per cent, of the crops were injured, and in the government of Tambov, 

 where it is specially injurious to wheat sown in strips, which method 

 of sowing also favours attack by other pests, such as Hessian fly, 

 eel worms, etc. A. A. Silantiev reported that in North Eussia, in 

 the governments of Tula and Novgorod, caterpillars of Trachea 

 (Hadena) secalis are found on rye and injure some 10 per cent, of 

 the crop, both the caterpillars and the injuries caused by them being 

 similar to those of 0. musculosa. A. A. Yaichevsky called attention 

 to the con;;rol of this moth by means of fungoid diseases and asked 

 for materials to be sent to the Bureau of Mycology.

The author refers first to the campaign against locusts which was con- 

 ducted in 1913 chiefly in the government of Tobolsk (Siberia) and also 

 in Central Asia and Caucasia, and to the favouiable results obtained 

 by means of chemical remedies, such as spraying with Paris green and 

 other insecticides. In the southern part of European Russia there 

 was again, in 1913, an outbreak of Phlyctaenodes sticticalis, the cater- 

 pillars of which attacked mostly beets and meadow plants ; reports 

 from various governments showed however that this pest was largely 

 dying out in some places owing to the infertihty of the females of the 

 second generation, as well as from other causes. Oria musculosa did great 

 damage in 1913 to crops in Ekaterinoslav and in the province of the 

 Don. Other important pests in South Russia were Trachea {Hadena) 

 hasilinea and Barathra {Mamestra) hrassicae in Charkov, and Brachy- 

 colus noxius in Taurida. In North Russia, the chief pests recorded 

 were the Noctuids, Tholera popularis, F., {Chareas graminis), which 

 destroyed grasses in some parts of Vologda, Euxoa (Agrotis) segetum and 

 Feltia exclamationis, which did much harm in Kazan, Viatka, Olonetz, 

 and Perm. With regard to Agriotes sp., the observations of the
