Phloroglucinol-type Furocoumarins, a Group of Potent Naturally-Occurring Insect Antifeedants

Abstract
Phloroglucinol-type furocoumarins were found to have strong antifeeding activity against Spodoptera litura (tobacco cutworm), but the other furocoumarins belonging to pyrogallolor resorcinol-type had only weak activity. Antifeeding activity of these compounds against the other insects was also reported.
