Larvicidal activity of Sapindus mukorossi on Aedes aegypti

Key Points

The aim is to evaluate the larvicidal potential of Sapindus mukorossi against Aedes aegypti larvae.
Methanol extract of Sapindus mukorossi was prepared using the percolation method.
Concentrations of 29 μg/mL were tested for larvicidal activity over 24 hours.
Larvicidal effectiveness was assessed by measuring LC50 and LC100 values.
100% larval mortality was achieved at a concentration of 29 μg/mL in 24 hours.
LC50 of the methanol extract was 11 μg/mL, while the active fraction had an LC50 of 5 μg/mL.
One fraction derived from the methanol extract achieved remarkable LC100 at 7 μg/mL.

Abstract

Aedes aegypti is an ecto-parasite and vector of the Dengue fever. New eco-friendly method to control the population of these insects is necessary. In the present study we evaluated the potential of Sapindus mukorossi as larvicide. Methanol extract prepared by percolation method outstand as highly active larvicide, achieving 100 % larval mortality in 24 hours when tested in the concentration of 29 μg/mL. One fractions derived from methanol extract present remarkable LC100 at 7 μg/mL. LC50 of methanol extract and active fractions were found 11 μg/mL, and 5 μg/mL respectively. These extracts will be further studied to determine its larvicidal principle and feasibility at field level.
