PROCESS OF PREPARATION AND APPLICATION OF INSECTICID COMPOUNDS OBTAINED FROM THE HYDROALCOHOLIC EXTRACT OF DONIM LEAVES (Azadirachta indica A. Juss) FOR THE ELIMINATION OF EGGS AND LARVAE OF Aedes aegypti. "The present invention refers to the preparation and application process obtained from the hydroalcoholic extract of Neem leaves (Azadirachta indica A. Juss) for the elimination of eggs and larvae of Aedes aegypti. The extract was obtained from Neem leaves submitted to the 70% (v / v) The alcohol was eliminated by evaporation, at low pressure, the extract obtained undergoes dilutions in water in the proportion of 10 to 90% to obtain the insecticidal compounds The insecticidal compounds must be applied in the place of infestation of eggs and larvae the Dengue Aedes aegypti mosquito. The insecticidal compound obtained in the proportion of 25% of the extract eliminated 100% of the eggs and 76% of the larvae of Aedes aegypti.
