Abstract
Abstract The interstate highways I-10, I-75, and I-95 are key routes for long-distance truckers carrying agricultural products between states and countries. These products often carry pests. Inspectors from the Florida Department of Agriculture and Consumer Services, Division of Plant Industry (FDACS-DPI) work with Agricultural Law Enforcement officers at agricultural inspection stations along these interstate highways. Samples of suspect pests are collected by DPI inspectors and sent for identification. From 2009 to 2021, there were 5,408 samples submitted to entomologists at DPI from inspection stations. These samples resulted in 14,835 interception identifications, of which 1,466 (9.9 %) were pests of regulatory significance to Florida agriculture. Of the regulatorily significant pests, 61.3 % were hemipterans. Several regulated hemipterans, including the potato psyllid, Bactericera cockerelli (Šulc) (Triozidae), are known to be vectors of plant pathogens that do not occur in Florida. Inspection station interceptions are an important tool for monitoring potentially invasive pests, as is demonstrated in the case of the Ligurian leafhopper, Eupteryx decemnotata (Rey) (Cicadellidae), which was intercepted alive at the agricultural inspection stations several times and subsequently found to be established in Florida in 2021. Interceptions at Florida’s agricultural inspection stations can include pests that are not yet present in the United States, such as the armored scale Davidsonaspis aguacatae (Evans, Watson & Miller) (Diaspididae). This species is regularly intercepted alive on avocados and threatens domestically grown avocados. Our data illustrate the importance of interstate highways as a pathway for agricultural pests and of inspection stations as an early warning system for invasive insects.
