Thus, control within outbreak areas could prevent plagues. Plague prevention was achieved for species with small, relatively accessible outbreak areas.

East Africa is bracing itself for a third outbreak of desert locusts, with billions of the destructive insects about to hatch and threaten food supplies in a region already reeling from damaging. THE recent report of the Committee on Locust Control is the sixth of its kind which deals with locust outbreaks in the regions mentioned. In the present instance it covers the year and the.
