^: The leaf-mining fly Hydrellia egeriae Rodrigues-Junior (Diptera: Ephydridae) was evaluated under quarantine conditions as a candidate biological control agent of the invasive aquatic weed Egeria densa Planchon (Hydrocharitaceae) in California, U.S.A. The objective of this study was to test the fly's feeding preference for E. densa as compared to the North American native Elodea canadensis Michaux (Hydrocharitaceae), an important benchmark species. No choice testing revealed that H. egeriae can complete development on E. canadensis and choice testing indicated the fly presents little oviposition discrimination between E. densa and E. canadensis. It is concluded that the host range of H. egeriae is too broad for use as a biological control agent of E. densa in the U.S.A. aref1
