A new invasive pest, the chilli thrips, is causing fear among Florida strawberry farmers and threatening crops across the state and beyond. The insect, which damages a variety of plants including strawberries, blueberries, peppers, and tomatoes, has already been spotted as far north as Massachusetts. The thrips, originally from Southeast Asia or India, suck sap from plants, causing leaves to blacken and fruits to discolor and crack, leading to potential crop loss of up to 80%.
University of Florida researchers warn that the pest could have a devastating economic impact on a wide range of crops, including bananas, cashews, corn, citrus, and grapes. With the potential to spread throughout California and beyond, the chilli thrips pose a risk to America’s food production.
The bug is not only resistant to insecticides but also adept at hiding from them, making chemical treatments ineffective. Farmers are exploring new methods to control the invaders, including importing predatory mites and breeding thrips-resistant plant varieties.
The pest likely arrived in the U.S. on imported produce and continues to spread through wind currents and hitching rides on existing plants. The thrips are small, about the thickness of a ballpoint pen tip, and hide under the calyx of berries, making them difficult to detect and eradicate.
With the potential for widespread damage and significant economic losses, farmers and researchers are working to find solutions to combat the chilli thrips and protect America’s food supply. Home gardeners may also notice damage to their plants and should be vigilant in monitoring for signs of infestation.
