Lansium domesticum Correa Extract as an Environmentally Friendly Larvacidal Activity and Identification

There are various approaches to prevent or reduce the transmission of dengue fever, one of which involves interrupting the vector's life cycle through the use of pesticides and biological control methods. Considering the significant impact of synthetic pesticides on the environment, the utilization of natural ingredients such as botanical pesticides is a prudent option. These have minimal to no adverse effects on the environment and are relatively safe for animals and humans. This research aimed to assess the efficacy of a larvicide derived from duku peel extract (Lansium domesticum Correa) against L3 larvae of Aedes sp. It employed a quantitative approach, utilizing an experimental design with a post-test control group. A purposive sampling technique was used to select a total of 600 larvae. The data collected were then analyzed using SPSS version 23. The initial test involved data normalization, with a p-value >0.05 indicating normal distribution of the data. Subsequently, the Pearson correlation test was conducted, revealing a significant correlation with a p-value of 0.000 <0.05. The variables had a strong connection at a Pearson correlation value of 0.998. Probit regression analysis was then performed, yielding results of 4.699 µg/mL for LC50 and 11.234 for LC90 µg/mL.
