Beetle-Based Biological Controls Successfully Manage Invasive Pests and Weeds in U.S.
Biological control using beetles has effectively managed invasive pests and weeds in the U.S. since the late 19th century. The USDA introduced the vedalia beetle to combat California's cottony cushion scale in 1888, saving citrus crops. Oregon deployed a flea beetle in 1971 to reduce toxic tansy ragwort by 90%, aiding livestock safety. Florida has relied on the alligatorweed flea beetle since 1965 to control invasive aquatic mats, which collapse within months of beetle establishment. These cases highlight sustainable pest management alternatives to chemicals.
