Jasim Al-Rahmanny Department of biology, College of Education, University of Samarra, Samarra, Iraq Journal Article 2022 06 01 This study evaluates the toxic impacts of <em>Rosmarinus officinalis</em> oil on the <em>M. domestisa</em> adults after 24- 48 h of treatment. The results showed that the activity of all oil concentrations have produced a mortality rate in laboratory when treating <em>M. domestica</em> adults. These results also revealed that the maximum significant difference was at the highest (100%) concentration among these treatments. The mortality rates in this insect were 86% and  100% after 24 and 48 h of the treatment respectively. The minimum mortality rates were 10% and 20% at the lowest concentration (25%) after 24 and 48 h of treatment respectively. https://cjes.guilan.ac.ir/article_5586_1db4ad520b17bd865b24fda7e2bc7abc.pdf
