| Deskribapena: | A series of 77 biological wall tests was carried out in a site of persistent malaria transmission, continually exposing Anopheles (A.) punctimacula to D.D.T. . 18. .months after the last spraying. A slight decrease in insecticide activity was detected, which, might also be interpreted as a decrease in the insect's susceptibility. In spite of either factor the tests suggest that mosquitoes resting on . a treated surface for period, close to the maximum here employed, would in any case accumulate a lethal dose of the insecticide. |
