ABSTRACT:Bithynia tentaculata is an aquatic invasive snail first detected in the upper Mississippi River (UMR) in 2002. The snail harbors a number of parasitic trematode species, including Sphaeridiotrema pseudoglobulus, that have been implicated in waterfowl mortality in the region. We assessed the capacity of S. pseudoglobulus cercariae to infect B. tentaculata and native snails found in the UMR. Four snail species (one invasive and three native) were individually exposed to S. pseudoglobulus larvae and all were successfully infected. A subsequent experiment examining infection patterns in invasive and native hosts exposed singly or in mixed treatments revealed no difference in parasite establishment among snail species. Our results add to our understanding of S. pseudoglobulus transmission and provide insight into processes underlying waterfowl disease in the UMR.

Bithynia tentaculata is an invasive snail that was first reported in Lake Michigan in 1871 and has since been rapidly spreading through the waters of the U.S. This invasion has been extremely problematic in the Upper Mississippi River, specifically Navigation Pools 7 and 8, as this area serves as part of the major migratory flyway. As an intermediate host for several exotic trematode parasites, B. tentaculata is associated with severe regional waterfowl mortality. This study was designed to assess the abundance and distribution of B. tentaculata relative to submersed aquatic vegetation (SAV) as it provides nesting and food resources for migrating waterfowl. Temporal changes at specific locations were assessed from 2007 to 2015 using the rake score method of the Long-Term Resource Monitoring Program to survey vegetation and snail densities. Data suggest that B. tentaculata densities have nearly quadrupled since 2007 despite minor changes in vegetation abundance, distribution, and composition. Understanding the spatial distribution of B. tentaculata in relation to other habitat features, including submersed vegetation, and quantifying any further changes in the abundance and distribution of B. tentaculata over time will be important for understanding the potential locations and magnitude of risks of disease transmission to waterfowl. iv ACKNOWLEDGMENTS

We used a comparative approach to investigate the effects of a copper-based pesticide (EarthTec® QZ) on embryos of an invasive snail (Bithynia tentaculata) and a native snail (Physa gyrina). Embryos were exposed to one of three treatments: control (0 mg/L Cu), low-dose (0.1 mg/L Cu), or high-dose (0.6 mg/L Cu), which reflect manufacturer-recommended low and medium 4-day molluscicide treatment concentrations. Exposure to 0.6 mg/L Cu over 4 days generated 100% mortality in both invasive and native snail embryos; however, reducing the exposure time from 4 to 1 day resulted in 100% mortality in B. tentaculata but some hatching (7%) in P. gyrina. In contrast, embryos of both species exposed to 0.1 mg/L Cu treatment for 4 days showed almost 100% survivorship. Further manipulations of Cu concentrations and exposure times may yield regimes that maximize mortality in B. tentaculata while minimizing negative impacts on native species.
