Anopheles albimanus males carrying an Y-autosome translocation were continuously released into a cage population at a ratio of 1:5 in favor of translocation males. The release caused a significant decrease in the absolute density of cage populations. Virtually complete replacement of wild type Y chromosome by translocated Y chromosome was observed after four generations. The results obtained from the cage experiments encourage actual field trials for the control of this vector species.
