The aim of this study was to evaluate the larvicidal activity of &lt;em&gt;Acroptilon repens&lt;/em&gt; against third instar larvae of &lt;em&gt;Anopheles stephensi, Culex pipiens and Culex quinquefaciatus&lt;/em&gt;. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; The aerial parts of &lt;em&gt;A. repens&lt;/em&gt; plants was dried in the shaded places for 3 days at 26-28&amp;deg;C. The leaves, flowers and stems were blended to crashed form using an electric blender. The larvicidal activity of total extract of &lt;em&gt;A. repens&lt;/em&gt; were evaluated against third instar larvae stage of mosquito vectors, &lt;em&gt;An. stephensi&lt;/em&gt;, &lt;em&gt;Cx. pipiens&lt;/em&gt; and &lt;em&gt;Cx. quinquefaciatus&lt;/em&gt; under laboratory conditions with 24h exposure period. Data were subjected to probit regression analysis in order to estimate the lethal concentrations for 50% and 90% mortality values. &lt;strong&gt;Result:&lt;/strong&gt; The extract of &lt;em&gt;A. repens&lt;/em&gt; exhibited significant larvicidal activity against third instar larvae of &lt;em&gt;An. stephensi&lt;/em&gt;, with 24h LC&lt;sub&gt;50&lt;/sub&gt; of 0.2970 and LC&lt;sub&gt;90&lt;/sub&gt; of 2.2097 mg/l. The LC&lt;sub&gt;50&lt;/sub&gt; and LC&lt;sub&gt;90&lt;/sub&gt; values were 2.5047 and 24.7374 mg/l for &lt;em&gt;Cx. pipiens&lt;/em&gt; and 2.9047 and 16.1459 mg/l for &lt;em&gt;Cx. quinquefaciatus&lt;/em&gt;. &lt;strong&gt;Conclusion:&lt;/strong&gt; The extract of &lt;em&gt;A. repens&lt;/em&gt; can serve as a natural larvicide against &lt;em&gt;An. stephensi&lt;/em&gt;, &lt;em&gt;Cx. pipiens&lt;/em&gt; and &lt;em&gt;Cx.quinquefaciatus&lt;/em&gt;. According to the larvicidal properties of this plant, formulating an extract of &lt;em&gt;A. repens&lt;/em&gt; which is known as an abundant agricultural weed in Iran creates an alternative to chemical larvicides and providing a job opportunities.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">453</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Ramesh Toolabi&lt;sup&gt;1&lt;/sup&gt;, Mohammad Reza Abai&lt;sup&gt;1*&lt;/sup&gt;, Mohammad Mehdi Sedaghat&lt;sup&gt;1&lt;/sup&gt;, Hassan Vatandoost&lt;sup&gt;1&lt;/sup&gt;, Mansooreh Shayeghi&lt;sup&gt;1&lt;/sup&gt;, Saeed Tavakoli&lt;sup&gt;2&lt;/sup&gt;, Mohammad Sistanizadeh Aghdam&lt;sup&gt;1 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
