In the search for alternative method beside the use of dangerous insecticides for health and the environment, the vegetable kingdom offers many possibilities. Work is carried out in this direction and showed an effectiveness of the extracts of plants. Our results indicate that the chloroformic contents present a better larvicide activity than other extracts. In addition, the analysis by chromatography (CCM) of the three extracts of seeds showed their wealth of flavonic compounds, alkaloids and tannins thus suggesting a correlation between the larvicide activity and the contents in secondary metabolites of seeds.
Keywords: Indigofera pilosa, stems, chloroformic extract, extraction, ccm, larvicide activity.
