A major potato pest, the Colorado beetle, has been successfully eradicated from the UK, according to the Department for Environment, Food and Rural Affairs (Defra).
Defra explained that the Colorado beetle is a significant threat to growers as they can completely strip the leaves from potato plants and several other crops – including tomatoes, aubergines, and peppers – and can have a significant economic impact if left uncontrolled.
The most recent outbreak of this invasive species was first discovered in Kent in July 2023, which was followed by two other findings later that year.
Following extensive operational work and surveillance activity, Defra and the Animal and Plant Health Agency (APHA) reported that no further Colorado beetles have been found in the space of two years, leading to an eradication status being reached.
The co-operation and vigilance of farmers, gardeners, and allotment holders has played a key part in the eradication campaign along with effective biosecurity measures from the APHA and Defra.

According to Defra, Colorado beetles primarily found their way into the UK through imported plant products, such as leafy vegetables, salad leaves, and fresh herbs.
Defra chief plant health officer, Prof. Nicola Spence highlighted the importance of reporting any future sightings to the appropriate authorities.
She said: “Colorado beetle can pose a significant threat to plants and the wider potato industry, and I’m grateful for the role of farmers, home gardeners and allotment holders in helping us take the action needed to protect our national crops.
“This has been a huge team effort and is good news for the potato industry, but in order to prevent further outbreaks, it is vital the public continue to be vigilant and report suspected sightings to the Animal and Plant Health Agency with a photo and location details.”
The Colorado beetle, which does not pose a risk to human health, can be identified by its orange-yellow colour and the 10 black stripes on its body.
