| The current research included evaluating the efficiency of alcoholic and alkaloid extract of the leaves and fruits of the Solanum nigrum and testing its effectiveness against the immature stages of the blue fly with 24 hours at concentrations of 5, 10, 15, 20 mg/mL at 30 ±1°C and a relative humidity of 60 ± 5 %. The alcoholic extract of the plant's fruits had the highest effect on the killing of blue fly eggs at all concentrations used, where the death rates were 89.11 and 42.43% at concentrations of 5 and 20 mg/mL, respectively, compared to the control (9.27%). As for the alkaloid extract, the alkaloid extract of the leaves of the plant outperformed in recording the highest rates of killing blue fly eggs, with a death rate of 88.83 and 31.14% in concentrations 5 and 20 mg/mL compared with the control amounting to 10.40%. As for the larval stages, the first stage was more sensitive than the other larval stages to all extracts of leaves and fruits of the plant. The highest rates of mortality of the three larval stages were achieved by using the alcoholic extract of the fruits with the highest concentration of 20 mg /mL compared with the alcoholic extract of the leaves, where the death rates of the third larval stage reached the highest rates (57.11, 68.20, and 88.69%) (53.19, 68.64, and 89.11%) of the alcoholic extract of the fruits and leaves, respectively. The recorded data showed that the alkaloid extract of the leaves of S. nigrum lead to achieve the highest mortality rates compared with the alkaloid extract of the fruits for all larval instars and at all the concentrations used. The mortality rates of the third larval stage with highest concentration were (58.13 - 67.64), respectively. With regard to the results of Gas chromatography-mass spectrometry (GC-MS) to investigate the chemical compounds in the alcoholic and alkaloid extract of leaves and fruits, the result showed the presence of chemical compounds of varying numbers. | ||
