The lower precipitated layer of a methanol extract of Citrus natsudaidai seeds, when applied to paper discs at a dosage ranging from 500 to 2000 μg/disc, significantly deterred feeding by Reticulitermes speratus nymphs. Three termite antifeedant limonoids (i.e., obacunone, nomilin and limonin) were identified as the active principles. Obacunone (with a minimum effective dosage of 150 μg/disc) was about two-fold more active than nomilin. Limonin was weak even at 1000 μg/disc.
