Abstract

Provincial Epidemiology Surveillance Unit (PESU) declared that Cavite is now a state of calamity due to the uprising number of dengue cases. The main objective of this study was to make pellet, liquid and granule larvicides out of the crude extracts of Lansium domesticum (Lanzones) peel and Carmona retusa (Wild Tea) leaves formulated against Aedes aegypti larvae. Two and a half kilo of wild tea leaves and lanzones peel was dried and ground. It underwent ethanolic extraction. Semi-solid isolates were liquefied using dimethyl sulfoxide (DMSO). Concentrations for the Wild Tea leaf extract ranges from 3,000-15,000ppm, the concentration of the Lanzones peel extract from 1,000-5,000 ppm and synergy from 2,000-10,000 ppm. Linear Probit Analysis was used to determine the LC50 and LC90 of the three groups. Results showed that either of the three groups, Wild Tea, Lanzones and Synergy, was eligible for the formulation of larvicides since it didn’t manifest any significant difference with the Positive Control-Abate® 1SG Mosquito Larvicide. Results were verified using the Tukey-Kramer Post Hoc Analysis. The three mentioned groups were then formulated to liquid, pellet and granule larvicides. Larvicidal activity of 97% was shown using the liquid, granule and pellet larvicide after the 48-hours exposure period. Usage of these efficient larvicides: pellet, liquid and granule can be a great help to the locals of our communities. Additionally, people can choose which of the three variants of larvicides will be more convenient to use based on their perspective. Thus, increasing the possibility of lessening of dengue cases in our local community.
