Abstract

The objective of this research was to assess the efficacy of the adapted plastic larval sucking duct (LSD) as to remove Aedes aegypti larvae and pupae from domestic water-storage jars. The result indicated that in 1 minute ten volunteers could use this equipment to remove 77.2% of larvae on average from a 50 liter jar. Whereas in a jar with 50 larvae and 50 pupae of Ae. aegypti, 73.5% of larvae and 23.4% of pupae on average were removed from the jar. In a field test, the study showed that 81.0%, 91.4%, 94.6% and 90.1% of larvae and pupae of Ae. aegypti were removed from 30-, 50-, 100- and 200-liter jars, respectively. While 76.8% of larvae and pupae were removed from a 300-liter square-shaped cement container. As the results, this equipment is useful in Ae. aegypti larvae and pupae control. The method is also simple and inexpensive so it might be an alternative to help people in communities protecting themselves from dengue and dengue hemorrhagic fever by getting rid of vectors at home.
