Abstract
Keywords: Sweet Basil, Mint-Basil, Pellet, Larvicide, Dissolution, Larvicidal Activity, Larvicidal Agent
The growing number of Dengue victims every year on the Philippines with a reported 371,500 cases as of November 2019, according to European Civil Protection and Humanitarian Operations (ECHO), brought about studies that seeks vector control. In this notion, this research with the purpose of creating an alternative solution to the fast propagation of mosquitoes was made. The goal is to make four types of larvicidal pellet made from 100% Sweet Basil, 100% Mint-Basil, 70% Sweet Basil and 30% Mint-Basil, and 70% Mint-Basil and 30% Sweet Basil. Guided with measuring only the duration of dissolution and larvicidal activity, with larvae drawn from clean stagnant water and canals, the dissolution property of the pellets with size ranging from 0.5-0.8 cm had a mean of 15 minutes and 57 seconds. Following Quasi-Experimental approach, each pellet type had three set ups with 20 larvae contained, 10 pellets were dissolved. Mortality rate ranges from 11.67%-20%, 20% from 100% Sweet Basil on 720ppm, 16.67% on 100% Mint Basil,320ppm, 15% on 70% Sweet Basil and 30% Mint-Basil, 480ppm, and 11.67% on 70% Mint-Basil and 30% Sweet Basil on 320ppm. Determining whether basil type and time interval affects mortality rate was measured through two-way ANOVA which showed that neither of the two nor its interaction affect the mortality rate of the pellets.
