The results of the present study, which aimed to demonstrate the efficacy of Lambdacyhalothrin 10% and alcoholic extracts of Datura innoxia fruits in the control of fourth larval instar and adults of the phlebotomus papatasi , indicated that the highest mortality percentage of the larval instar was 100% in concentration 3 μL / ml, and the lowest mortality percentage of 33.3% at the lowest concentration of 0.05 μL / ml. The results of adult treatment were the highest mortality percentage of 93.33% at the concentration of 3 μL / ml and the lowest mortality percentage were 20% at concentration of 0.05 μL / ml after 24 Hour of treatment.
The results of the treatment of the fourth larval instar with the Datura innoxia fruits extracts showed that the highest mortality percentage was 100% for the concentration of 2000 ppm and the lowest of 13.3% at 75 ppm. The highest mortality percentage of adults insects was 100% when treated with the most effective concentrations (1600, 2000ppm). Thus, the results are shown to be affected by the control method used and the interaction of the insect larval instar to this method. In the end, there was a convergence of the effect of the insecticide and extract in the larval instar and adults insect.
