The main pest of the crop is the onion thrips, which causes leaf necrosis and reduces the market quality of the heads. Plant resistance to infestation is determined by morphological characteristics, in particular, the intensity of wax bloom development on the leaf surface.

crop Red cabbage,
where this is mentioned in the description.
The onion thrips Thrips tabaci poses a serious threat to red cabbage by feeding on leaf sap. External signs of damage include silvery or grey spots on the underside of leaf blades, which turn brown as necrosis develops, as well as the presence of pest excrement in the form of small black dots.
The pest is capable of penetrating the head, leading to the appearance of rusty spots, which sharply reduce the market quality and storage life of the produce. No specific resistance genes to this pest have been identified in red cabbage; therefore, breeding is based on the selection of varieties with a pronounced epicuticular wax bloom, which acts as a mechanical barrier.
