MONTADA DORTA, Domingo et al. Effectiveness of Sipertrin 5 SC for Aedes aegypti control in Santa Clara, Villa Clara. Rev Cubana Med Trop [online]. 2013, vol.65, n.3, pp. 350-360. ISSN 0375-0760.

Introduction: the use of insecticide-treated materials is one of the strategies currently recommended by the World Health Organization (WHO) for the prevention and control of vector-borne diseases. Even though insecticide-impregnated materials have not been used in Cuba, several pyrethroid insecticide formulations have been in use since 1986 for the control of various vector species. Objective: determine the effectiveness of pyrethroid insecticide beta-cypermethrin, formulated as Sipertrin 5 SC, for the control of Aedes aegypti. Methods: effectiveness of Sipertrin 5 SC was determined by three procedures: residual treatment of resting sites-perifocal, impregnation of curtains, and combination of the two, applying the methodologies recommended by WHO, all of which was carried out in households from Condado Norte Council, 20th Anniversary health area, in the municipality of Santa Clara, Villa Clara. Bioassays were conducted to determine the effectiveness of this pyrethroid on various surfaces, following the methodology recommended by WHO. Results: the greatest residual effect was obtained with the combined treatment (resting sites, perifocal treatment and curtain impregnation), with an effectiveness of up to 5 months. In households undergoing resting site and perifocal treatment, residuality was 4 months. Effectiveness of the product was highest on plastic and concrete surfaces, with a mortality rate of 95 to 100 % up to three months. On metal surfaces mortality was 85%. Conclusions: Sipertrin 5 SC is a candidate to be considered for possible inclusion in Aedes aegypti control programs in Cuba. Its use will contribute to the sustainability of the strategies implemented.
