モンシロチョウ
Species in the genus "Iberis" contain not only glucosinolates, which are characteristic chemical defenses of the Brassicaceae plant family, but also cucurbitacins, which are better known as chemical defenses in the Cucurbitaceae plant family. Cucurbitacins from "Iberis amara" have antifeedant activity against the Brassicaceae-feeding specialist "Pieris rapae" (cabbage butterfly). Cucurbitacins from "Iberis umbellata" (globe candytuft) are ecdysteroid antagonists, acting on the ecdysteroid receptor of insects.
