Insect antifeedant activity associated with compounds isolated from species of Lonchocarpus and Tephrosia

The antifeedant activity of a series of 21 chalcones, flavanes, and flavanones isolated from the genera Lonchocarpus and Tephrosia (Leguminosae) was assessed by behavioral and electrophysiological bioassays against larvae of Spodoptera littoralis and S. exempta. The antifeedant activity is related t...

Zusammenfassung:	The antifeedant activity of a series of 21 chalcones, flavanes, and flavanones isolated from the genera Lonchocarpus and Tephrosia (Leguminosae) was assessed by behavioral and electrophysiological bioassays against larvae of Spodoptera littoralis and S. exempta. The antifeedant activity is related to the molecular structure of the compounds, and possible modes of interaction with the insect taste receptors are discussed
