Abstract:
The present experiment was conducted at toxicology laboratory of Entomology, Dr. PDKV, Akola, during kharif 2019-20, to find out the “Antifeedant activity of some botanical extracts against Spodoptera frugiperda under laboratory condition in Factorial Completely Randomized Design. The results revealed that amongst different botanical extracts 1% neem seed kernel extract followed by 1% lantana leaf extract and amongst different solvents used to extract the solvent ethyl acetate followed by hexane were observed with the highest antifeedant activity. In interaction study 1% neem seed kernel extract by using ethyl acetate recorded highest antifeedant activity against S. frugiperda in their third instar larval population and found at par with 1% neem seed kernel extract by using methanol and 1% lantana leaf extract by using ethyl acetate at 48 hours followed by 72 and 24 hours after treatment. A novel and cheap botanical extract against S. frugiperda is thus developed in this study.
