VILLASECA C, Pablo et al. Validación de sustratos atractivos a oviposición para la detección de Aedes Aegypti. Rev. perú. med. exp. salud publica [online]. 2001, vol.18, n.3-4, pp.77-81. ISSN 1726-4634.

Objective: To compare three types of oviposition baits (local water, Stenotaphrum secundatum solution and 0.5%-methyl propionate solution) for the detection of Aedes aegypti in three Dengue endemic cities in Peru. Materials and methods: Based upon one confirmed Dengue case and in the occurrence of Aedes pupae and larvae, a selective sampling of houses in Tarapoto (San Martfn), Satipo (Junin) and Tumbes (Tumbes) was performed between September and October, 2001. Four traps (containing the three solutions, as well as a control solution: mineral water) were placed in each house and observed for a 3-day period, being supervised every 24 hours. The Duncan Multiple Test and the Dunnet Test (significance level, p < 0,05) were used to perform the analysis. Results: Of 248 traps placed (88 in Tarapoto, 88 in Satipo and 72 in Tumbes) in 62 houses, 13.7% were positive. The average egg content for each trap was 8,02 (range: 0-131) and the average egg content found in the vegetable infusion was higher than those met in the other solutions (p<0,05). Conclusion: The vegetable infusion is the most effective trap bait used for detection of Aedes aegypti.
