Toxicity of Acacia arabica leaf extract for the control of Aedes aegypti mosquito larvae-A laboratory study

Abstract

The primary objective of this research was to test the effectiveness and LC50 value of babool (Acacia arabica) leaf extract as a bio larvicide for Aedes aegypti. This research was a laboratory experimental study consisting of 6 treatments and 4 replications. The treatment groups consisted of babool leaf extract concentrations of 0.25%, 0.50%, 0.75%, and 1.0%. Next, the extract was tested for its effectiveness as a larvicide on test animals in the form of Aedes aegypti larvae in third instar. The results of the research were data analysed using Analysis of Variance (ANOVA) followed by Probit Analysis and determining the LC50 value. The research results showed that babool leaf extract (Acacia arabica) was effective as a bio larvicide with an LC50 of 3303 ppm or equivalent to a concentration of 0.33%. The Insect Growth Regulator test findings indicate that it has the same impact as pyriproxyfen at all fatal concentrations. The study's findings indicate that the ethanol extract of babool leaves inhibits the growth of insects and acts as an ovicide against the Aedes aegypti mosquito.
