Description
Summary:To investigate the acaricidal activity of different extracts from Syzygium cumini ( S. cumini) (Pomposia) againsst Tetranychus urticae Koch ( T. urticae) and the biochemical changes in antioxidants enzymes. Six extracts of S. cumini (Pomposia) at concentrations of 75, 150 and 300μg/mL were used to control T. urticae (Koch). The ethanol extract showed the most efficient acaricidal activity agent against T. urticae (98.5%) followed by hexane extract (94.0%), ether and ethyl acetate extract (90.0%). The LC 50 values of the promising extract were 85.0, 101.0, 102.0 and 98.0μg/mL, respectively. The activities of enzymes including ascorbate peroxidase (APX), peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) in susceptible mites were increased. The activities of all antioxidant enzymes reach the maximum value in mites at LC 50 with ethanol and ethyl acetate extracts, respectively. The extract of S. cumini has acaricidal acivity against T. urticae, and the ethanol extract is the most efficient.
