Susceptibility And Some Biological Aspects Of Ceratitis capitata (Wiedemann) As Influenced By Different Crude Extracts Of Nerium oleander L.

A trial was conducted to evaluate the toxic impact of Nerium oleander L. leaf extracts against Ceratitis capitata (Wiedemann), adults.Acetone, ethanol, petroleum ether, and water were used to extract the N. oleander leaves contents.Leaves crude extract with ethanol was the most toxic than the other three extracts based on lethal concentrations (LC 50 and LC 90 ), recording the values of (2.62 & 4.75), (1.68 & 3.29), and (1.10&d 2.23) g/ml post 24, 48 and 72 h of application.Also, the ethanol extract at the LC 50 showed the ability to decline some biological aspects such as the fecundity (number of eggs laid), hatchability percentages, and triggered retardation in larval duration in comparison with the control.Conclusively, the research recommends that Nerium oleander, extracted with different solvents, has a toxic impact against Ceratitis capitata under laboratory conditions.
