Aedes mosquitoes are the major cause of several vector-borne diseases in tropical and subtropical regions. Synthetic pesticides against these have certain limitations; hence, natural, eco-friendly, safe larvicides obtained from plant resources used to overcome these. In present study, larvicidal efficiency Commiphora wightii fourth instar stage dengue fever mosquito aegypti (Linnaeus, 1762) was studied. The gum resin C. collected using borehole tapping method, hexane extracts different concentrations were prepared. fourth-instar larvae exposed extracts, percent mortality, as well LC20, LC50, LC90, calculated. Volatile compounds extract analyzed by Headspace GC/MS, sequence acetylcholine, Gamma-aminobutyric acid (GABA) receptor, octopamine receptor subunit A. obtained. It found that toxic lethal for at concentrations. Minimum mortality observed 164 µg mL-1 (10%/h), while maximum 276 (50%/h). LC90 197.38 mL-1, 294.13 540.15 respectively. GC/MS analysis confirmed presence diterpenes, monoterpenes, monoterpene alcohol, sesquiterpenes samples, which due their inhibitory activity on acetylcholinesterase enzyme, GABA subunit. use commonly occurring control explored, it had activities could be potentially insecticidal.
