Amygdalin, a cyanide-releasing compound, is produced by some plants to deter herbivores.[1]
Antifeedants are organic compounds produced by plants to repel herbivores through distaste or toxicity. These chemical compounds are typically classified as secondary metabolites in that they are not essential for the metabolism of the plant, but instead confer longevity. Antifeedants exhibit a wide range of activities and chemical structures as biopesticides. Examples include rosin, which inhibits attack on trees, and many alkaloids, which are highly toxic to specific insect species,[2] such as quassinoids (extracts from Quassia trees) against the diamondback moth (Plutela xylostella).[3]Samadera indica also has quassinoids used for insect antifeedant uses.[4]
Limonoids such as limonin are antifeedants produced by a number of plants of the families cucurbitaceae Rutaceae and Meliaceae.[5]
