Cabbage seed weevil

Ceutorhynchus assimilis

Return to listing

Seed weevils invade OSR crops as temperatures increase during May. After about 3 weeks of feeding the females begin to lay eggs in the pods and this continues until seeds are formed.

Adult feeding does not affect yield, so treatment is not necessary during migration into crops. Larvae feeding in the pods can cause severe losses with up to 60% of pods affected, but a single spray of Decis before egg laying will control this damage.

Additional yield losses may result from Brassica pod midge which can exploit feeding damage and egg laying scars to deposit their eggs
