Abstract
The transmission intensity of bancroftian filariasis was investigated during a study on filariasis control performed in 8 villages of the savanna area in the hinterland of Liberia. Although the microfilarial reservoir was reduced considerably in the human population of 2 villages by mass treatment with the filaricide drug diethylcarbamazine, the transmission of W. bancrofti was continued without any distinct reduction. The transmission decreased distinctly or was even interrupted when residual spraying with DDT was used in 2 other villages for vector control. The combined application of both control measures did not completely prevent mosquitoes becoming infected with mature stages of W. bancrofti.
