Texas A&M experts released new management guidance following the discovery of invasive short-spined thrips on hibiscus and pepper plants in the Dallas region. The pest, which was first detected in the U.S. in 2020, has since spread across several states due to the ornamental plant trade.
Why it matters
The Texas climate provides favorable conditions for the insect to persist, making early detection vital for slowing the spread to new host plants. With over 40 known plant hosts, the arrival of this pest poses a significant risk to local ornamental and food crops.
Female short-spined thrips measure between 1 and 1.2 millimeters in length and are known to infest more than 40 different host plant species. The pest feeds on various plant structures, including leaves, flowers, petioles, fruit, and buds.
The players
Texas A&M
Texas A&M is a public research university that provides extensive agricultural extension services to the state.
The details
Growers can identify the insects by utilizing sticky traps or by shaking plant samples over a white surface to spot the tiny pests. Researchers are currently evaluating the efficacy of several chemical pesticides, including abamectin, flonicamid, and tolfenpyrad, alongside biological control agents like Swirski mites and minute pirate bugs.
Timeline
2020: The invasive thrips were first discovered in Florida.
Late 2025: Short-spined thrips were confirmed to have reached Texas.
October 2026: Texas A&M published official guidance for managing the pest.
Culture Shift
The introduction of the short-spined thrips into Texas highlights the vulnerabilities inherent in the global ornamental plant trade. As species move through commercial supply chains, local ecosystems face increasing pressure to adapt to non-native pests that exploit regional climate similarities.
Gardeners and commercial growers should adopt a routine of checking hibiscus and pepper plants over white surfaces to catch early infestations. Proactive monitoring is the most effective way for residents to prevent the further spread of this pest throughout the area.
The takeaway
Early identification is the most critical tool for homeowners to protect their garden plants from this invasive species. By utilizing sticky traps and regular physical inspections, gardeners can help prevent the pest from becoming established in their personal landscapes.
