The hibiscus bud weevil is the most important insect attacking hibiscus plants in southern Florida. This pest immigrated to Florida from Mexico and South Texas within the last decade. It is closely related to both the boll weevil and pepper weevil. Currently, the hibiscus bud weevil is a regulated insect due to its significant presence and widespread plant damage, especially in Miami-Dade County, FL. Thus, detecting small populations of the pest is critically important for preventing strict quarantine regulations that restrict plant movement and harm nursery growers.

Consequently, researchers are developing new integrated pest management (IPM) programs. These programs combine yellow adhesive-coated liners with targeted insecticides. No natural predators or parasites directly attack the hibiscus bud weevil, though researchers at the University of Florida’s Tropical Research and Education Center are actively exploring potential biological control agents for this pest.

Kevin Cloonan, PhD, Trécé’s Pete D. Lingren Behavioral Entomology & Chemical Ecology Laboratory Director, is currently collaborating with government and university researchers to identify the insect’s natural pheromone. A breakthrough with this technology will significantly improve the efficacy of the yellow card liners used for monitoring. Additionally, University of Florida researcher Dr. Alexandra Revynthi is collaborating with researchers at the USDA ARS Subtropical Horticulture Research Station investigating the pest’s biology and ecology to develop more effective IPM tools to manage it.

The yellow STKY CANOPY trap pairs perfectly with Trécé’s yellow double-sided adhesive-coated HBW STKY liner. Together, they form the ultimate early detection trapping system for the hibiscus bud weevil. Furthermore, the new STKY CANOPY traps provide early capture and extended monitoring. They achieve this by utilizing a precise yellow color with the exact reflectivity required to attract the pest. Ultimately, Trécé’s early detection trapping system is critical for determining when to spray, ensuring the most cost-efficient results.
