Les Syndicats de Defense centre les Sauterelles. [Syndicates for Defence 

 against Locusts.] — Rev. Agric. Afr. Nord, Algiers, xix, no. 105, 

 5th August 1921, p. 604. 



As a result of enquiry into the present organisation against locusts, 

 it is found that 183 communities out of the 365 that comprise Algerian 

 territory have formed syndicates for this purpose. This response to 

 the appeal for the formation of syndicates is considered inadequate.

In this report of a meeting of the permanent committee of the 

 International Agricultural Institute held 27th May 1916 the advisability 

 of calling an international conference for the organisation of anti- 

 locust measures is discussed. A resolution was passed [R.A.E., 

 A, V, 192] and the conference took place at Rome, 28-31 October 1920. 

 The general plan for this conference is outlined and certain proposals 

 are suggested on which the ultimate resolutions were based [R. A.E., 

 A, ix, 87].

In the course of these proceedings of the International Conference 

 for the organisation of anti-locust measures, an agreement was drawn 

 up that has already been noticed [R.A.E., A, ix, 87]. This publica- 

 tion also includes a copy of the resolutions passed at the 1st Inter- 

 colonial Conference for the control of locusts in South Africa in 

 August 1916. 



In accordance with the clause in the agreement, by which special 

 arrangements are permissible between any of the States that wish 

 to take combined action, a meeting was held, attended by the delegates 

 representing Egypt, Tripoli, Tunisia, Algeria, Morocco and French 

 West Africa, at which a definite plan of action was adopted. Each 

 of the above-mentioned countries is to carry out scientific biological 

 studies, the results of which are to be conmiunicated to the crop 

 protection service at .Algiers. This service is to fonn a centre for the 

 amalgamation and dissemination of such information. The appear- 

 ance of winged locusts is to be reported immediately to the service, 

 which will prepare flight charts to be forwarded to all the interested 

 countries between the 1st and 14th of every month.
