ResumoA limited field trial was undertaken to determine if larvicidal treatment of open containers of stored water could achieve effective control of A. aegypti (Dipt., Culicidae), a vector of dengue fever and dengue haemorrhagic fever. The insecticide used was abate 1% sand granules and the method of evaluation was the single-larva-per-container method. The lethal effect of each application at a concentration of 1 ppm lasted 3 to 3.5 months and was reflected in the resurgence and reinfestation of the species. A higher proportion of larvae collected from indoor containers were A. aegypti. A. albopictus larvae in outdoor water collections tended to increase markedly during the trial. A. aegypti comprised 64.8% of the larval collections, A. albopictus 28.3% and other species, principally Culex pipiens fatigans 6.9%. The single-larva-per-container technique provided a useful quantitative measure of the larval densities in the treated areas.
