Oregano (Plectranthus amboinicus) and Lemongrass (Cymbopogon) as Primary Ingredients for Liquid Mosquito (Culicidae) Larvicide

Abstract

Mosquito-Borne diseases or diseases that spread from host to host are a big problem around the world. This study intends to find out if processed Oregano (Plectranthus amboinicus) and Lemongrass (Cymbopogon) natural extract can be used as an inexpensive and environmentally friendly mosquito larvicidal solution. Based in some studies Oregano (Plectranthus amboinicus), and Lemongrass (Cymbopogon) contains natural chemical that can kill larvae in their early stage. The researchers used two (2) set-ups with four (4) containers including one (1) control group which will be the basis of the experiment, all the containers are containing twenty (20) live mosquito larvae from the Institute of Weed Science, Entomology and Plant Pathology (IWEP) of University of the Philippines, Los Baños, Laguna. The researchers added different concentrations and ratios of the solution in each container in this experiment. As the experiment conducted, the results show that less than fifty percent (50%) of the specimen was eliminated in the whole set-up, The experiment revealed that Oregano and Lemongrass larvicide solution is not enough to reach what this study aims for. Also, experiment results indicate that Oregano and Lemongrass solution is not enough to kill the larvae of mosquitoes. The researchers conclude that the Oregano (Plectranthus amboinicus), and Lemongrass (Cymbopogon) larvicide solution is not effective as an alternative mosquito (Culicidae) larvicide solution.
