AbstractAbstract
[en] In this study, using the life cycle interruption test with the Drosophila melanogaster model, under (in-vitro conditions), the n-Hexane (roots and stems) and the EtOAc (roots and leaves) extracts were evaluated as insecticides and the results were promising. The larvae instars showed a significant activity reflected in the reduction of pupae population with respect to the control. The step from Pupae to adult did no show inhibition because in all cases the average of the relation pupae adult is found in values very near 1. The n-Hexane and the EtOAc extracts from roots were the most active with LC50 of 698.2 ppm and 1210.7 ppm. The n-Hexane (stems) and EtOAc (leaves) extracts showed a moderate activity with LC50 of 1654.1 ppm and 2376.0 ppm
