Abstract
A series of flavones with widely varying degrees of substitution was fed to neonate larvae of the navel orangeworm. Growth of navel orangeworm larvae is inhibited by 5-methoxy flavones and flavone itself; 5-hydroxy flavones do not inhibit growth. Host resistance of citrus fruit to attack by the navel orangeworm might be due to the 5-methoxy flavones that occur in the peels.
