title: Malaria control in the Gezira-Managil Irrigated Scheme of the Sudan.
abstract: The development of malaria control in the Gezira-Managil Irrigated Scheme of Central Sudan has gone through several phases. As a result of agricultural and irrigation practices in the Gezira, falciparum malaria transmission became perennial instead of seasonal and the mosquito vector developed resistance to several insecticides. Subsequent failure to maintain control led to serious epidemics after 1971. By 1975 malaria was again put under control through an annual round of house spraying with malathion from 1975 to 1980, and with fenitrothion since 1981. A proposal is outlined for a rational strategy for malaria control in the future.
