LIMA, Milton Moura and ARAGAO, Mario B.. Tratamento focal e perifocal contra Aëdes aegypti. Cad. Saúde Pública [online]. 1987, vol.3, n.2, pp. 142-147. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X1987000200002.
In four districts of the city of Rio dc Janeiro focal treatment essays with granulated Abate at 1 ppm and perifocal treatment essays with wettable powder of Sumithion at 2,5% were performed. These were made either alone or in combination as well as associated to insecticides applied at ultra low volume. The premise indices obtained one month after the treatments indicates that the focal treatment alone is effective, no other addicional methods being necessary. The perifocal treatment is not effective and did not prevent the development of Aedes aegypti larvae and other insects in tires which had their external surface painted with Sumithion and Malathion.
