Hexane and methanolic extracts of plant Scutellaria  scandens and  Hyptis suveolens was prepared and compounds were isolated by means of column chromatography. The antifeedant activity of methanol and hexane extracts were tested for antifeedant activity using leaf dip method in term of % growth reduction.Isolated compounds were tested for antifeedant activity using duel choice leaf disc method against Spodoptera litura a polyphagous pest of cotton rice, tomato, tobacco, groundnut, castor and legumes.  Methanol  extracts of Scutellaria scandens exhibit maximum growth reduction followed by hexane extract of Hyptis suveolens , hexane extract  of Scutellaria scandens and methanol extract Hyptis suveolens

 

Key words: Spodoptera litura, antifeedant activity, Himalayan Plants
