Evaluation of the in Vitro Efficacy of Capparis spinosa L. Alcoholic Extract in Controlling the Hairy Grain Beetle (Khabra) Tragoderma granarium Everts (Coleoptera; Dermestidae)

This research was carried out to investigate the effects of the alcoholic extract of the leavesand roots of C. spinosa, at concentrations of 10, 20, and 30 mg/ml on the larvae of the second andfourth instars of the hairy grain beetle (Khabra) T. granarium. The results showed the superiority of the alcoholic extract of the leaves at the concentration of 30 mg/ml in killing thesecond and fourth larval instars, with mortality rates of 48.3 and 60.0%, respectively. As for thealcoholic extract of the roots, the concentration of 30 mg/ml caused the highest mortality rate inthe second and fourth larval instars, with mortality rates of 23.3 and 28.3 %, respectively.
