ABSTRACT
We conducted a laboratory study to evaluate the effect of the aqueous and alcoholic extract of Mentha spicata on some aspects of the live performance of B. tabaci. The results of the study showed that the alcoholic extract in concentrations of (1, 2, and 3) mg/ml. It had a significant effect on the non-cumulative mortality of the different roles of the insect, where the concentration of 3 mg/ml excelled, as it reached the highest percentage of the mortality rate in the nymphs and adults (81.3% and 76.0%), respectively, at a concentration of 3 mg/ml after 72 hours. While the mortality rate for nymphs and adults in the aqueous extract at the same concentration was (74.3% and 68.7%), respectively, after 72 hours. The results showed that there is a direct relationship between the concentration of the extract and the percentage of mortality rate.
