being the more harmful, injuring the trees by defoliating them, as 

 well as destroying the fruit. Spraying with California mixture before 

 the leaves unfold gave excellent results. Aphids were controlled by 

 spraying with soap quassia emulsion (2 lb. of quassia, 3 lb. of soft soap 

 in about 18 gallons of water). A species of E'picaula destroyed whole 

 fields of potatoes and lucerne in some localities.

These are the minutes of a meeting of the Turkestan Agricultural 

 Society, held on 8th June 1916, to consider measures against an 

 outbreak of Dociostaurus (Stauronotus) maroccanus. After 1911, when 

 the previous outbreak of this locust was finally checked, no damage 

 was done by it until 1916, when it reappeared in large numbers and 

 seriously threatened the cotton crops among others. 



The entomologists present at the meeting pointed out the impossi- 

 bility of completely exterminating locusts in the province, owing 

 to the presence of mountains and of large grass areas scattered over 

 immense steppes and other places inaccessible to man, providing 

 favourable breeding grounds. The absence of a permanent organi- 

 sation dealing exclusively with the destruction of locusts, even in years 

 when the danger is small, also aggravates the difficulties of the 

 situation. 



The meeting finally passed a series of resolutions, which were sub- 

 mitted to the Ministry of Agriculture and which call for the creation 

 of a permanent independent organisation for the control of locusts in 

 Turkestan, at the head of which should be placed an officer with 

 wide powers and an adequate staff of assistants. In order to safe- 

 guard the permanence of this organisation, it should be created a 

 statutory body by act of Parliament. The Entomological Station 

 should be relieved of the many onerous duties connected with the 

 actual campaign.

The author has been in charge of the campaign against locusts, 

 Dociostaurus {Stauronotus) maroccanus and Locusta migratoria, in 

 part of Tashkent, where as many as 10,800 acres were infested with 

 the egg-clusters ; the cost of these operations amounted to about 

 £2,500. The campaign was carried on by various methods, including 

 spraying with Paris green, locusticide and sodium arsenite, the last 

 two proving the more effective ; with poisoned baits of dung, clover 

 or bran soaked in Paris green or locusticide, the first proved more 

 suitable and gave very good results. For various reasons, chiefly the 

 delay in the delivery of insecticides and the inadequate carrying out 

 of the preliminary investigation during the preceeding year, the
