Beet moth (S. ocellatella) is a major pest of sugar beet crops in Europe, North Africa and Asia. Since its first detection in Poland a few years ago S. ocellatella has spread rapidly, causing extensive damage and is now one of the most serious threats to sugar beet. This problem is linked to climate change, high pest fecundity, its polyvoltinism and initially almost latent feeding. Scrobipalpa ocellatella causes crop losses directly by feeding on plants and indirectly by creating favorable conditions for the growth of pathogens causing rot diseases. Heavy contamination of the beet crown with larval excrement creates ideal conditions for secondary fungal and bacterial infections. Sugar beets with severe root rot delivered to sugar plants are in many cases unsuitable for processing.
