Anna Mészáros of the UF/IFAS Palm Beach County Extension office and Dr. Julien Beuzelin of the UF/IFAS Everglades Research and Education Center recently began investigating the increase in unusual insect injury observed since 2020 in conventional and organic celery and parsley fields in southern Florida. This injury consisted of weevil larval tunneling through plant petioles, crowns, and roots. A research and extension program was initiated to identify the insect causing the injury, study pest population dynamics, evaluate insecticide efficacy, and promote information exchange to answer grower needs.
We are thankful for our great collaborations with Florida celery and parsley growers and crop consultants who have shared their knowledge and have assisted with on-farm experiments to develop a management solution for L. sparsus.
