摘要：In the course of an insecticide-testing programme, fenthion was applied in mud-walled huts at an intended concentration of 1.5 g/m2 in a village near Lagos, Nigeria. This paper describes the entomological results obtained. Bio-assays on Anopheles gambiae showed an effective kill (i.e., over 70%) for 7 weeks on mud surfaces, 11 weeks on wood surfaces and 16 weeks on raffia-palm mid-ribs. No mosquitos were found in pyrethrum spray catches in the treated village for 7 weeks after the application of fenthion, although low numbers persisted in the control village near by.
