Pollen beetles

Time to act:

Jun, Jul, Aug, Mar, Apr, May

In spring and summer, pollen beetles fly in from nearby oilseed rape crops to gather in open flowers where they feed on ripe pollen. Mostly, the beetles do little harm although occasionally they may nibble into unopened flower buds and damage the developing flowers of cauliflowers.

Symptoms

Flower heads are infested with small bronze-green shiny beetles that spread pollen over petals.

Pollen beetles can be a nuisance if you want to bring cut flowers indoors. Stand the flowers in a bucket somewhere dark for a few hours, say a shed, but near to a bright window or lamp. The beetles will fly up towards the light. Grow brassica crops under fleece or very fine mesh netting.
