| Resumo: | Studies were made in Belém, Pará, on the duration of the toxic effects of residual DDT on Anopheles darlingi. Wooden walls were sprayed with DDT in kerosene solution at 5%, leaving a residue of 2.09gm per square meter. It was found that toxic effects of the insecticide disappeared completely following the eighth month of application. Any observations referring to mortality caused by DDT in mosquitoes maintained without feeding should be made from the 8th to the 24th hour after capture; in the 48th hour, the percentage of deaths from natural causes is very high. |
