In this division, the essential lubricate (EO) of the occurring in the air parts of Foeniculum vulgare Mill (Umbelliferae: Apiaceae) was gleaned by hydro-distillate. Thereafter, its synthetic arrangement was checked utilizing vapor chromatography (GC), and the description was acknowledged utilizing smoke chromatography-bulk spectrometry (MS).The toxicity of the EO was evaluated, following in position or time 24h of uncovering occasion, against the divide into four equal parts instar larvae of Aedes caspius and the sublethal and deadly concentrations, LC25, LC50 and LC90 principles were supposed accompanying their assurance limits and their values are 27.65, 37.76 and 70.40 l individually. Based on the judgments of the toxicity of F. vulgare EO, it maybe decided that the current pungent plant variety proved a abundant toxicological effect and grant permission offer a suitable give assistance the control of mosquitoes. This verdict opens up interesting potential for allure use in the production of new beginnings of different larvicidal alive stuffs for the management of pest headings.
