« WypHanij ripMKnaAHOil 3HT0M0Jl0riM.» — [Journal of Applied Entomo- 

 logy], Kiev, vol. 1, no. 1, 1917, xx & 114 pp., 23 figs. [Received 

 10th May 1917.] 



This is the first part of a new journal published by the Russian 

 Association of Workers in Applied Entomology, the Editors being 

 V. V. Dobrovliansky, I. V. Emelianov and A. G. Lebedev. The 

 Association came into existence as a result of a resolution to that 

 effect passed by the Kiev Entomological Congress in 1913 [see this 

 Review, Ser. A, iii, p. 245] and the inaugural meeting was held in 

 Kiev in November 1915. The object of the Association is to promote 

 the progress of Applied Entomology in Russia. 



The journal will comprise original articles on Applied Entomology 

 and Zoology and an index of the Russian literature on Applied 

 Entomology will be issued yearly, as a supplement. Among the 

 papers read at the first meeting were : " The methods of ascertaining 

 moisture in thermostats," by I. V. Emelianov [see this Review, Ser. 

 A, iv, p. 169], and " The rearing of Trichogramma semblidis, Aur., 

 and T. fasciatmn. Perk., in the laboratory and temperature 

 experiments on them," by A. P. Bragina [see this Review, Ser. A, 

 V, p. 155].

A large outbreak of Lymantria. dispar occurred in the Crimea in 

 1913, but in 1914 the pest practically disappeared. The reasons for 

 this were : — the presence of parasites, principally Tachinids, which 

 destroyed some 30 per cent, an epidemic disease resembling flacherie 

 which destroyed another 10 per cent., and the shortage of food due 

 to the great numbers of caterpillars which totally defoliated the trees ; 

 the pupae and adults were consequently of very small size and the 

 majority of the adult moths were males. Whereas the females bred 

 under normal food conditions contain up to 1,200 eggs, those from 

 localities suffering from a shortage of food contained only from 60 

 to 200, and the less food there was in a given locality the greater the 

 percentage of males reared in it.

The outbreaks of Oria musculosa, which have taken place in the 

 government of Ekaterinoslav and in South Russia generally since 

 1910, reached their maximum in 1914 [see this Review, Ser. A, iii, 

 p. 110]. In 1915 the development of this moth was principally checked 

 by a Braconid parasite.
