EX WT. & ARN) SWINGLE (RUTACEAE) AGAINST AEDES AEGYPTI, ANOPHELES STEPHENSI AND CULEX QUINQUEFASCIATUS (DIPTERA: CULICIDAE)}, url={https://innoriginal.com/index.php/iijs/article/view/88}, abstractNote={<p><strong>               </strong>The present study was conducted to evaluate the essential oil from the leaves of<em> Pleiospermium alatum</em> (Wall. ex Wt. & Arn) Swingle (Rutaceae) was evaluated for mosquito larvicidal activity against the larvae of <em>Aedes aegypti, Anopheles stephensi</em><em> </em>and<em> Culex quinquefasciatus</em>. GC and GC- MS analyses revealed that the essential oil contain fourteen compounds. D-Limonene (34.02%) was identified as a major chemical compounds followed by Elemol (18.04%) and <em>γ</em>–Terpinene (11.83%). The larval mortality was observed after 12 and 24 hours of exposure periods. The results revealed that essential oil potential larvicidal activity against the 4<sup>th</sup> instar larvae of <em>A. aegypti, A. stephensi</em><em> </em>and<em> C. quinquefasciatus</em>. After 12 h of exposure period the larvicidal activities were LC<sub>50</sub>=95.2 and LC<sub>90</sub>=366.7 ppm (<em>A. aegypti</em>), LC<sub>50</sub>=72.6 and LC<sub>90</sub>=305.2 ppm (<em>A.stephensi</em>) and LC<sub>50</sub>=104.4 and LC<sub>90</sub>=373.6 ppm (<em>C. quinquefasciatus</em>) and the larvicidal activities after 24 h of exposure period was LC<sub>50</sub>=53.8 and LC<sub>90</sub>=251.0 ppm (<em>A.aegypti</em>), LC<sub>50</sub>=44.4 and LC<sub>90</sub>=213.8 ppm <em>(A. stephensi)</em>, and LC<sub>50</sub>=143.3 and LC<sub>90</sub>=375.5 ppm (<em>C. quinquefasciatus</em>). The present study showed the leaves of the essential oil from the<em> P. alatum</em> and its D-Limonene major compound may have potential for use in control of <em>A<em>. aegypti</em></em>, <em>A. stephensi</em> and <em>C. quinquefasciatus and could be useful in search of new,</em> safe, inexpensive and more effective control of vector mosquitoes. <strong></strong></p><p><strong>Key Words:</strong><em> Pleiospermium alatum.<strong> </strong></em>GC-MS. <em>Aedes aegypti.
