     One of the major concerns in the agricultural systems is the progressive replacement of the synthetic pesticides with natural substances less polluting, less toxic and less expensive for a better management of predatory of the agricultural food products. Many studies have focused on improving forms of using plants that enhance and leverage their insecticidal activity. In this study, we sought to evaluate the potentialities of the roots of Anacyclus pyrethrum (L.) (Asteraceae) against adults, eggs and the emerging of Callosobruchus maculatus (Fab.) (Coleopter : Bruchidae), the main pest of Leguminosae stored food. The tests were carried out on seeds of Cicer arietinum (L.) (Leguminosae) in the temperature of 28.0 ± 2.0 °C, photoperiod  12/12 and relating humidity from 70 to 75%. The results obtained showed that the various doses of aqueous extract tested reduced longevity, fecundity, number of fertile eggs, fertility and success rate of these insects. This indicates that a durable protection and at low cost against this beetle is possible by using the aqueous extract of A. pyrethrum, which can represent an interesting alternative solution to chemical insecticides.
