Insecticidal bioactivity of eco-friendly plant origin chemicals against Culex pipiens and Aedes aegypti (Diptera: Culicidae)

Zeinab Sh. Abou-Elnaga

Mosquitoes are the most important medical insects in the entire world. Natural chemicals have many advantages over the conventional ones in case of mosquito control. The aim of this study is to evaluate the larvicidal and adulticidal bioactivity of some plant origin chemicals against Culex pipiens and Aedes aegypti (Diptera: Culicidae). The chemicals under investigation of Myristicin, Sage oil and Nutmeg oil were isolated and structurally elucidated using GC/MS, and 1H-NMR, spectra that compared with the authentic samples. Myristicin was the highest larvicidal bioactive compound with LC50 values 18.3 ppm against Cx. pipiens and Ae. aegypti, larvae after 24 h of treatment, respectively. The rest of the tested materials showed also high larvicidal and adulticidal activities that may be related to their volatile bioactive constituents. From the results of this study; its highly recommend the tested natural chemicals to be an alternative eco-friendly source for mosquito control chemicals.
