Abstract

Research explains evaluating the efficiency the alcoholic and alkaloid extract of the leaves and fruits of Solanum nigrum and testing its effectiveness against the immature stages of the green bottle fly Lucilia sericata within 24 hours at concentrations (5, 10, 15, 20, 0.0) mg/ml, at a temperature of 30 ± 1 and a relative humidity of 60 ± 5%. The alcoholic extract of the plant's fruits had the highest effect on killing Lucilia sericata eggs in all the concentrations used, where the death rates reached (42.34 - 89.11) % at concentrations 5 and 20 mg/ml, respectively, compared to the control amounting to 9.27 % alkaloid extract, of leaves excelled in recording highest rates killing for green bottle fly eggs with a death rate of (35.58- 68.41) % in concentrations 5 and 20 mg/ml compared with the control of 10.40%. The first larval stage was more sensitive than the other larval stages to all extracts of the leaves and fruits in different used concentration, where the highest rates mortality of third larval stages when 20mg/ml of fruit alcoholic extract compared with the alcoholic extract of the plants leaves. The percentages mortality of the third larval stage with the highest concentration (53.19, 57.11)% for the extract of alcoholic for fruits and leaves respectively as for the extract of alkaloid, we find that the alkaloid extract of the leaves more efficient than the alkaloid extract of the fruits in recording the highest death rates for all larval stages with all the used concentrations, the mortality rates of the third larval stage with the highest concentration were (58.13 - 66.09%) for the alkaloids fruits and leaves respectively.
