The Effectiveness of Reactivation of Long Lasting Insecticide Nets (Llins) on Mosquito Killing Power Aedes aegypti

Abstract

Vector, especially mosquitoes, is the main cause of vector-borne diseases including malaria, dengue fever and filariasis which are still a public health problem in the world, including Indonesia. Efforts to control vector-borne diseases can be carried out in various ways, including biological, physical, chemical and environmental engineering. Mosquito control in malaria areas is carried out by using various methods of indoor residual spraying (IRS) and use long lasting insecticide nets. Long enough use of long lasting insecticide nets can cause dust and dirt. It is necessary to reactivate the long lasting insecticide nets. The purpose of this study was to determine the reactivity effectiveness of long lasting insecticide nets on the killing power of Aedes aegypti mosquitoes. This research method was pre-experimental the static group comparation with a control group design. The research was carried out by controlling the long lasting insecticide nets without reactivation and treatment with reactivation on the long lasting insecticide nets. Each confinement of 20 Aedes aegypti mosquitoes and the application was carried out for 3 days with 3 replications. The results showed that reactivation of long lasting insecticide nets with clean water had an average death rate of 15 mosquitoes (75%). Reactivation with detergents had an average death rate of 14 mosquitoes (70%), there was no significant difference in the various reactivation methods (p value = 0.209), meaning that various reactivation methods used in the study could be carried out but must pay attention to the detergent dosage used. The conclusion of this study is that there are no differences in the various ways of reactivation with clean water or detergent on the killing power of Aedes aegypti mosquitoes and based on the results of the reactivation effectiveness test of the long lasting insecticide nets used that 45 months of use are no longer effective for controlling vector-borne diseases. For other researchers, reactivation of long lasting insecticide nets for no more than 30 months is used with various reactive methods to determine the effectiveness of the killing power of mosquitoes.
