Evolution of egg-killing in Brassicales
Members of the Brassicaceae family are known to express a hypersensitive response(HR)-like necrosis when cabbage white butterflies (Pieris sp.) lay eggs on their leaves. The plant responds with a local cell death in the leaf under ...

Natural selection of (anti-) sex pheromones by egg parasitoids
Butterfly males can produce and transfer an anti-sex pheromone, a
so-called anti-aphrodisiac (AA), to females during mating to render them less
attractive to other males. AAs from cabbage white butterflies, Pieris
brassicae and ...
