However, the combined treatment of &lt;em&gt;T. purpurea + B. sphaericus&lt;/em&gt; (1:2) material shows highest larvicidal activity of the LC&lt;sub&gt;50&lt;/sub&gt; values 80.08, 82.21, 88.00, 92.21 and 98.16 ppm; The LC&lt;sub&gt;90&lt;/sub&gt; values of 108.39, 118.71, 136.75, 149.02 and 153.24 ppm, against &lt;em&gt;A. aegypti&lt;/em&gt; in all the tested concentrations than the individuals and clearly established that there is a substantial amount of synergist act. &lt;strong&gt;Conclusion:&lt;/strong&gt; The present study reported that both &lt;em&gt;T. purpurea and B. sphaericus&lt;/em&gt; materials could serve as a potential larvicidal agent. Since, &lt;em&gt;A. aegypti&lt;/em&gt; is a container breeder vector mosquito this user and eco-friendly and low-cost vector control strategy could be a viable solution to the existing dengue disease burden. Therefore, this study provides first report on the mosquito larvicidal activity the combined effect of &lt;em&gt;T. purpurea&lt;/em&gt; leaf extract and &lt;em&gt;B. sphaericus&lt;/em&gt; against as target species of &lt;em&gt;A. aegypti&lt;/em&gt;.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">737</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Ramesh Venkadachalam&lt;sup&gt;1&lt;/sup&gt;, Vijayakumar Subramaniyan&lt;sup&gt;1&lt;/sup&gt;, Manogar Palani&lt;sup&gt;1&lt;/sup&gt;, Mahadevan Subramaniyan&lt;sup&gt;1&lt;/sup&gt;, Prabhu Srinivasan&lt;sup&gt;1&lt;/sup&gt; and Murugan Raji&lt;sup&gt;2&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
