LANSIUM DOMESTICUM CORR. LEAF EXTRACT SPRAY AS BIOINSECTICIDE FOR AEDES AEGYPTI MOSQUITO CONTROL
Background: Dengue Haemorrhagic Fever vector eradication using chemical insecticides showed that mosquitoes have become resistant and they cause environmental pollution. Duku (Lansium domesticum corr.), Indonesia's native plants, is a natural ingredient used as bio insecticide. The skin of fruit, seeds and stems contain alkaloids, flavonoids and saponins that have insecticide activities. This study aims to determine the efficacy of duku leaf extract as a bioinsecticide for Aedes aegypti mosquito control.
Materials and Methods: It used pre-test post-test only method. The samples are 500 mosquitoes for the experimental design of 5 treatment groups and 4 replications. Factors used as treatment were concentrations of extracts (35%, 40%, 45% and 50%) and controls (distilled water) were examined for 24 hours and measured the percentage of mosquitoes died. Anova was used followed by Least Significant Difference.
Result: The results showed the number of mosquitoes died at each concentration showed a significant difference (p<0.001). At a concentration of 35% the number of dead mosquitoes was 87.75%; 40% was 97.5%; 45% was 63.75%; 50% was 58.75% and in controls was 16.87%. LC50 calculation results of duku leaves were at a concentration of 35.97%.
Conclusion: It concluded that duku leaves can be used as a vegetable insecticide with an effective concentration of 40%.Keywords: Aedes aegypty, Bio insecticide, Lansium domesticum, Extract, Duku
