Interplay of pollinators and pests influences plant evolution

Interplay of pollinators and pests influences plant evolution

Brassica rapa plants pollinated by bumblebees evolve more attractive flowers. But this evolution is compromised if caterpillars attack the plant at the same time. With the bees pollinating them less effectively, the plants increasingly self-pollinate. In a greenhouse evolution experiment, scientists have shown just how much the effects of pollinators and pests influence each other.
