Renowned TV gardener Alan Titchmarsh has issued a warning to gardeners in the south of the UK about the reappearance of a ‘savage’ beetle that poses a significant threat to crops. The Colorado beetle, which has not been seen in the UK for half a century, has resurfaced, sparking concerns about potential crop devastation.
The beetle, known for its voracious appetite for potato plants and other vegetation, can swiftly decimate entire crops if left unchecked. Titchmarsh emphasized the urgency of addressing the issue promptly, likening the beetle’s impact to that of locusts due to its rapid and destructive nature.
Gardeners and farmers are urged to be vigilant and report any sightings of the Colorado beetle to the Animal and Plant Health Agency (APHA). The distinctive beetle is between 6mm and 11mm long, yellow or cream-colored with 10 black stripes, and features an orange head with irregular black spots.
Historically, outbreaks of the Colorado beetle have occurred in the UK, with previous instances in the 1930s, 1950s, and 1970s. Swift eradication measures were implemented during these periods, underscoring the importance of public awareness and proactive pest management strategies.
Professor Nicola Spence, Defra’s Chief Plant Health Officer, highlighted the grave threat that the Colorado beetle poses to plants and the potato industry. She emphasized the crucial role of public vigilance in swiftly identifying and reporting suspected sightings to safeguard biosecurity.
Dr. Jenny Stewart, Interim Chief Executive of the APHA, emphasized the pivotal role of public surveillance in protecting UK borders from plant pests like the Colorado beetle. She underscored the need for collective action from home gardeners, allotmenteers, and farmers in identifying and reporting potential beetle sightings.
Recognizing the distinctive features of the Colorado beetle is crucial for early detection. The beetle’s body is yellow or cream with black stripes, an orange head, and measures between 6 to 11mm in length. Additionally, its larvae, which are pinkish red or orange with black spots, can grow up to 15mm in length.
Visitors to the APHA’s exhibit at the Chelsea Flower Show can engage with interactive displays that highlight the beetle’s destructive impact on plants and provide guidance on identifying signs of infestation. The exhibit aims to educate the public on reporting suspected beetle sightings to protect the British potato industry.
If a Colorado beetle is found in England and Wales, individuals are advised to capture it in a secure container and promptly report the sighting to APHA. Similar protocols apply to Scotland and Northern Ireland, where specific contact information is provided for reporting suspected beetle sightings in those regions.
The resurgence of the Colorado beetle serves as a stark reminder of the ongoing battle against plant pests and the critical role of public vigilance in safeguarding agricultural crops. With swift reporting and coordinated efforts, the threat posed by these destructive beetles can be effectively mitigated.
