Cabbage stem flea beetle (CSFB) and its management in oilseed rape

A lack of effective chemical options in oilseed rape has accelerated the rise of cabbage stem flea beetle (CSFB). This beetle is now pest enemy number one in this crop, with its management resting on a rapidly developing, variable and complex set of alternative solutions.

Why cabbage stem flea beetle is an issue

Without effective chemical protection, CSFB has become more problematic. Critically, the pest can destroy a plant’s growing point and cause crop failure. Learn about the beetle’s life cycle and the factors that influence crop risk.

Cabbage stem flea beetle IPM

Our research has identified the key components of an integrated pest management (IPM) strategy for CSFB and used a traffic-light code to indicate the current reliability for control. Effective management relies on a combination of these components.

Cabbage stem flea beetle treatment thresholds

CSFB has developed resistance to pyrethroid insecticides to various degrees, so it is essential to target – even avoid – sprays as much as possible.

Cabbage stem flea beetle counts

As part of our 'reducing the impact of cabbage stem flea beetle' project, researchers are using water traps and sticky traps to count beetles during autumn 2021.

As this data is available, we are publishing the results in the tool below.
