of the locust question in North Caucasia must be based on co- 

 operation between the individual anti-locust organisations by means- 

 of yearly conferences, etc., the revision of and radical changes in 

 the law applying to the campaign, and the creation of special funds 

 in each of the affected governments. 



The Locust Section of the Congress, after a discussion on the papers 

 by Sacharov, Uvarov (see above) and Schreiner (see below) adopted 

 the following resolutions : — (1) The chemical method is at the present 

 time the most successful and efficient, all other methods being 

 admissible only under special local conditions ; (2) the control of 

 locusts must be made compulsory for all the affected localities and 

 all groups of the population. The suggestions of B. Uvarov as to- 

 special funds and co-operation between anti-locust organisations, as 

 well as the necessary changes in the law, were approved. These 

 resolutions were confirmed by the Congress.

The necessity of creating a special Entomological Bureau for the 

 province of the Don is suggested and the urgency of the matter is- 

 illustrated by a few instances of the enormous damage done in that 

 province by various insect pests ; large areas infested with egg- 

 clusters of locusts, especially of Caliptamus (Caloptenus) italicus were 

 noticed in some parts of the government ; Eurygaster integriceps, Osh., 

 has infested some 135,000 acres of forest ; over a million acres of 

 field crops, including at least 234,000 acres of summer-sown wheat 

 of a value of half a million sterling, are threatened by various insect 

 pests ; outbreaks of Epicometis hirta, Poda, and of Phlydaenodes 

 sticticalis, L., have also occurred in the province.

A large number of injurious Orthoptera occur in the Transcaucasian 

 steppes, the most important being Dociostmirus {Stauronotus) maroc- 

 canus, Thunb., Locusta {Pachytylus) danica, L., Caliptamus (Calop- 

 tenus) italicus, L., and Oedaleus nigrofasciatus, De Geer, their multipli- 

 cation being controlled only by various parasites. Of late years, 

 large outbreaks of D. maroccanus have constantly occurred, while an 

 increase in the numbers of L. danica has also been observed. 



It is thought that D. maroccanus originally bred on the wild plants 

 in the steppes of Transcaucasia, having arrived there from Persia, 

 but lately it has become a local species, concentrating in the steppes 

 near cultivated fields and annually causing enormous damage. The 

 best contributory means towards the destruction of this pest, both in 

 Transcaucasia and in the neighbouring Persian Moghan steppe, would 

 be the intensive colonisation of the countr}^, which tends to transform
