Brassica crops can be infested by up to 49 different species of pest insect. Fortunately, most of these occur infrequently on horticultural Brassicas. They include flies, beetles, caterpillars, aphids and whiteflies. Pests can reduce yield and crop quality through direct feeding damage, transmission of plant viruses and contamination

Turnip yellows virus (TuYV), is spread by aphids, mostly the peach–potato aphid (Myzus persicae). The virus can dramatically reduce yields, especially when plants are infected early in the growing season. It is well established in Europe, and is especially common in areas of intensive brassica production in UK.
