Effectiveness of Exterminator Anopheles Spp Larvae from Clove Leaf Waste (Syzygium Aromaticum)

Objective: The current reliance on chemical vector control methods raises concerns about their long-term environmental impact. To address these concerns, we need to explore alternative vector control strategies that are environmentally friendly, effective, efficient, and safe for human health. One promising approach involves the use of plant essential oils. This study aims to determine the effectiveness of residual waste clove leaf oil (Syzygium aromaticum) as an exterminator of Anopheles sp. larvae. Methods: This study used experimental methods carried out at the Entomology Laboratory of Donggala Health Research and Development Institute. It used third-instar Anopheles sp. larvae obtained from the field. The material used is clove leaf oil, which is a by-product of the distillation of clove leaves. The solution used to kill Anopheles sp. larvae uses five different concentrations, specifically 0.006%, 0.007%, 0.008%, 0.009%, and 0.01%. Results: This study shows the ability of waste clove leaf oil (Syzygium aromaticum) to eradicate Anopheles sp. larvae with lethal power LC50 at a concentration of 0.005%. The study found that the number of Anopheles sp. larvae that died varied significantly depending on the concentration of the solution. The difference was statistically significant (P 0.05). Conclusion: Waste clove leaf oil (Syzygium aromaticum) can be used as an ingredient to eradicate Anopheles sp. larvae.
