Diamondback moth is a significant and economically important pest of cabbage family crops. Ecologists Gurr et al. review the biological control options for diamondback moth management as sustainable alternative to – or complementary to – insecticides. They show that landscapes with a diversity of vegetation types promote natural enemy species that improve biological control of diamondback moth. For example, woodlands serve as refuges from which natural enemies can efficiently recolonize nearby brassica crops
