Abstract: Introduction Dengue viruses transmitted principally by the urban mosquito Aedes aegypti cause one of the major public health problems confronting tropical cities Insecticide spraying has been the mainstay of mosquito control however its continuous use has selected for resistance Other important methods of control involve community participationObjective This study evaluated two control methods for Ae aegypti that can be used by the community Lethal ovitraps LOs and Bacillus thuringiensis var israeliensis Bti briquettesMaterials and methods The project study was carried out in four similar neighborhoods within a representative district in the city of Cali Colombia Three interventions LO Bti LOBti plus education and one control education only area were evaluated for efficacy in postintervention entomological surveys Additionally entomological indices were also compared to results from a preintervention survey carried out on a sample of city blocks in the same neighborhoods Relative vector abundance in relation to weather conditions using the same entomological sampling methods was comparedResults The interventions did not achieve significant differences in vector abundance among the treatments However the interventions achieved a significant reduction in entomological indices compared with those observed during the preintervention survey House index 151 vs 85 mean pupae per house 115 vs 0073 and Adult index 563 vs 348 p005Conclusions The lack of significant differences among the interventions and between treated and control blocks suggested that educational activities together with periodic visits to the houses produced similar reductions of immature and adult Aedes aegypti
