UF/IFAS Faculty Celebrate Successful Completion of the Air Potato Biological Control Extension Program

Research and extension faculty with UF/IFAS have reached successful completion of the five-year Air Potato Biological Control Extension Program. UF/IFAS project partners are: Dr. Carey Minteer (lead) with the Indian River Research and Education Center and Ken Gioeli (co-lead) at the UF/IFAS Extension St. Lucie County.

This program began in 2014 as an initiative by the UF/IFAS Indian River Research and Education Center and the UF/IFAS Extension St. Lucie County in collaboration with Extension offices and partner agencies throughout Florida. The focus of the project involved the introduction of a new biological control agent Lilioceris cheni (Coleoptera: Chrysomelidae) to helped teach residents how to use the insect to manage the invasive air potato (Dioscorea bulbifera). Floridians struggled to control this invasive vine which can grow up to eight inches per day and smother native vegetation. This UF/IFAS research and extension program was paired with a mass rearing effort and distribution process that helped citizens throughout Florida. Researchers at USDA ARS are credited for discovering L. cheni as a viable biological control agent for air potato.

The program has been highly successful with tens of thousands of L. cheni beetles provided to stakeholders for release. It significantly increased the general knowledge of invasive species of the people surveyed by an average of 227 percent and general knowledge about biocontrol by an average of 401 percent. Perception of the safety of biological control increased by an average of 434 percent and perceived effectiveness of biocontrol increased by 344 percent. The combination of a charismatic and effective natural enemy along with an educational program has significantly increased the knowledge about invasive plant species and the knowledge and acceptance of biocontrol as a safe and effective control method.

The Air Potato Biological Control Extension Program was recognized with three national awards and one state award.
While UF/IFAS has completed research and extension activities with this project, educational resources will continue to be made available online at http://bcrcl.ifas.ufl.edu/airpotatobiologicalcontrol.shtml. This website features information about insect availability from project partners.
