Growing Brussels sprouts: Part 3

The diamondback moth, cabbage worm, cabbage looper, flea beatle and aphid are five common pests of Brussels sprouts.

• The diamondback moth (Plutella xylostella)

This is a particularly troublesome threat to Brussels sprouts due to its tolerance of many chemical insecticides.

This pest is a small, greyish-brown, night-flying moth with a 2cm wingspan. It holds its wings together, roof-like over its back, when at rest.
