ABSTRACT

An experimental study was carried out in 4 homes of Villa Nueva community of Tegucigalpa, in Honduras, to evaluate the effectiveness and residual 1% temephos (Abate^®) in controlling Aedes aegypti larvae from October 2007 to April 2008. Field and laboratory bioassays were performed; those from the field were made in 9 water tanks for domestic use, such as "pila" and barrels, which were initially inspected for the presence of larvae, so that if they were positive, temephos was applied -- according to its capacity in liters--, and if they were negative, then they were used as a control group. Furthermore, observations were made at 24 hours after applying the treatment, and then weekly for about 4 months (which were compiled in a register) in order to check the presence of larvae and measure the values of dissolved chlorine, pH and water temperature. On the other hand, the laboratory bioassays was made in the Abate-treated water from "pila", and the percentages of larvae mortality were determined at 24 hours of treating the liquid. Effectiveness of the Abate^® and its residual level of more than 100 days were evidenced, in spite of the influence of environmental, social and anthropogenic factors.
