Abstract

The aqueous crude of twenty-five flora sourced from the southern and high precipitation zone of Tamil Nadu were screened for their antifeedant and insecticidal potential against the test insect (Spodoptera litura). It was identified that Wrightia tinctoria exhibited maximum potency with the concentration of 5% to give 87.24% antifeedancy accompanied by Cipadessa baccifera (85.51%) and Dodonaea viscosa (81.03%). Insecticidal activity was more pronounced in Glorisa superba (99.99%) and Wrightia tinctoria (99.99%) at 2% concentration.
