title: Analysis of Insect toxicity and repellent activity of Phytochemicals from "Skimmia laureola, Nair" against "Black garden ant, Lasius niger" of Pakistan.
abstract: A study was conducted to evaluate the toxicity and repellency of essential oils from root, stem and leaves of Nazar panra, Skimmia laureola (DC.) Zucc. Ex Walp. of family (Sapindales: Rutaceae) ver. Nair of Pakistan. The oils were tested at three concentrations i.e. 1, 5 and 10%. Black garden ant, Lasius niger L. (Hymenoptera: Formicidae) of Pakistan were selected and exposed to essential oils at room temperature. All essential oils showed Insecticidal activity with LC(50)=10.15, while dose dependant effect was significant with R(2)=0.98. It can be concluded that the three Essential oils in this study have both Insecticidal as well as repellent effect.
