Field assessment of the residual effect of deltamethrin (20 mg/m2) against Anopheles arabiensis (Diptera : Culicidae) mosquitoes was performed during evaluation of the malaria vector control programme in Mpumalanga Province, South Africa. Ten treated sleeping rooms, five of which were mud- and five cement-walled, were used in bioassays with laboratory-reared An. arabiensis. The bioassays were run for seven consecutive months after treatment. Seven months after treatment deltamethrin-treated surfaces were still completely effective against the susceptible strain of An. arabiensis, with a 24-hour holding mortality of 100%.
