Damage caused by Thrips parvispinus, an invasive insect, is costing vegetable and ornamental plant producers millions of dollars. The Foundation for Food & Agriculture Research is providing the University of Florida a $137,441 Rapid Outcomes from Agricultural Research (ROAR) grant to develop tactics that control the pest. The University of Florida and Bedner Growers, Inc. are providing matching funds for a total investment of $274,882.
The first recorded observation of T. parvispinus in the continental United States was in Florida in 2020. By 2022, Florida’s vegetable farms and ornamental plant nurseries were experiencing significant damage, with one pepper grower alone reporting estimated losses of $1 million to T. parvispinus. The insect has since spread to seven states and poses a serious threat to vegetable production, especially peppers. Little is known about conditions that favor the insect or how to effectively manage it.
Researchers led by Dr. De-Fen Mou, assistant professor of entomology at the University of Florida, are monitoring T. parvispinus in vegetable crops to better understand how it chooses host crops. Additionally, the research team is evaluating pesticide efficacy in peppers to identify an effective chemical control program.
