A strategy of malaria control.
A field investigation was designed to determine the feasibility of a single annual application of DDT which could fulfil the objectives of malaria control. The concept of a single spraying cycle would eliminate the risks and disadvantages associated with the standard methodology of two spraying cycles, and would result in logistic and economic gains to the country. The timing of the spraying cycle in this modified control methodology is based on the determination of the malaria season solely from entomological data. Details of the field investigation for the years 1974 and 1975, the parameters for calculation of vectorial capacity, estimates of the relative malaria receptivity within the study area, and determination of the malaria season of six months' duration have already been published. The present paper applies the concept of a single spraying cycle to the findings of the investigation and discusses the implementation of the strategy.
