Madre de Cacao (Gliricidia sepium)Leaves Extract as a Main Component in Making Mosquito Coil Repellent

Abstract

INTRODUCTION

The DOH suspected dengue cases from January 1 to August 5 2017, they recorded 58,598 cases in the Philippines. and they also suspected Japanese encephalitis cases from January 2017 to August 5 and have recorded 392 cases with 9 deaths in the Philippines. With this, the researcher decided to make a mosquito repellent because of the number of cases of dengue and Japanese encephalitis in the Philippines.

METHODS

The researcher used Madre de Cacao as a component in making mosquito repellent in a form of coil. The coil was made by: first, the Madre de Cacao leaves were extracted using cheesecloth, then, the materials such as the extract and dried Madre de Cacao leaves were mixed. There were different concentrations of Madre de Cacao leaf extracts and dried leaves on the 4 treatments. After that, the coil was used to mold the mixture then it was placed inside the oven for 10 minutes and the molder was removed. Lastly, the coil was tested and observed using incubated mosquitoes. The characteristics of the coil were evaluated by grade 3-6 MScI students of Jose Rizal Memorial School.

RESULTS

The researcher found out that the properties of the coil were observed on each treatment, in which treatment 1 had the longest burning time and ignition time while treatment 4 had the most mosquitoes repelled. With these, it can be concluded that every time the Madre de Cacao leaf extract increases, the number of mosquitoes repelled also increases.

DISCUSSIONS

Based on the data that the researcher gathered, it was concluded that every time the Madre de Cacao leaf extract was increased, the number of mosquitoes that are repelled also increased.
