Antioxidant and insecticidal effect of squirting cucumber, Ecballium elaterium extracts against Aphis craccivora and Phthorimaea operculella

Hanan S Gaballa, Mona N Wahba and Magda H Naroz

The aim of this study was to test the antioxidant and insecticidal activity of these extracts against, Aphis craccivora (Homoptera: Aphididae) and Phthorimaea operculella (Lepidoptera: Gelechiidea). Results showed that the antioxidant activity of different extracts ranged from 10 to 1000 μl/ml. Where found that ethanolic and acetone extracts were having higher activity than other extracts and standard by radical DPPH scavenging and Hydroxyl radical scavenging activity. Identification of phenolic compounds of ethanolic extract was carried out by GC / MS / MS analysis. It has been shown that, E. elaterium may contain compounds that can act as botanical pesticides. Three concentrations (100, 500 and 1000 µg/ml) of each dry extract were obtained by dissolving the dry extract in 0.01% solution of dimethyl sulfoxide (DMSO). The Results showed that the high concentration (1000µg/ml) of the extracts caused high mortality of A. craccivora adults after 72h from exposure. Both the acetone and ethanol extracts showed higher mortality (68 and 71% respectively) than the hexane, chloroform and ethyl acetate extracts (42, 58 and 63%, respectively). All extracts reduced larval penetration deterrent of P. operculellaat concentration 1000 ug/ml. The data demonstrated that ethanol, chloroform and acetone extracts were highestreduction percentage of larval penetration of P. operculella 70.5%, 72.1% and 73.3%, respectively, at the same concentration.
