- Abstract
Superior plants are a diverse source of potent bioactive agents, some of which have significantly contributed to the successful use of natural products in insect's pest management. In order to evaluate the bio-insecticidal potential of an Algerian desert plant: Euphorbia guyoniana, a study was conducted on Tribolium castaneum: red flour tribolium. A crude ethanolic extract was prepared and then tested in the laboratory during the adult stage. Five different doses were tested. The results of the phytochemical study showed that the plant is rich mainly in flavonoids, gallic tannins, alkaloids, saponosides and glucosides. The plant does not present anthocyanins, leuco-anthocyanins, catechins, coumarins and iridoids. For the insecticidal activity, the repulsive of the extract at a dose of 700 μg/is low, it is 33.33 ± 23.09%. According to the percentages ranking of McDonald et al. (1970), the extract of this plant is classified in the 2nd class. The extract of this plant proved toxic against the adults of this insect, and the total mortality (100%) was reached 48 h after treatment with the highest dose (700 μg/insect). The LD50 obtained at the shortest time (6 hours after treatment) is 169.82 μg/insect. The extract of this plant did not inhibit the AChE activity on the tested adults. The results suggest that this plant does not have a neurotoxic effect on the triboilum. The encouraging results obtained with the extract of this plant suggest the possibility of the use of metabolites of this plant for the formulation of botanical bio-pesticides.
