Common salvinia, Salvinia minima Baker, is an aquatic invasive fern that obstructs waterways and impacts water quality throughout the southeastern United States. In an effort to establish populations for classical biological control, the weevil, Cyrtobagous salviniae Calder and Sands, was released at multiple sites across Louisiana. Many of the release sites were lost due to a variety of ecological and anthropological disturbances. In 2008, C. salviniae was found to have successfully overwintered on S. minima in Gramercy, Louisiana. Attack by Cyrtobagous salviniae significantly increased the number of damaged terminal buds and decreased the fresh weight biomass of S. minima.La salvinia común, Salvinia mínima Baker, es un helecho acuático invasor que obstruye vías fluviales y afecta la calidad de agua por el sureste de los Estados Unidos. Para fundar poblaciones de control biológico clásico el gorgojo Cyrtobagous salviniae Calder y Sands fue introducido en múltiples sitios por toda Louisiana. Fueron perdidos muchos sitios de introducción debido a varias alteraciones ecológicas y antropológicas. En 2008 fue notado que C. salviniae invernó exitosamente en S. mínima en Gramercy, Louisiana. El ataque de Cyrtobagous salviniae aumentó apreciablemente la cantidad de brotes terminales dañados y disminuyó la biomasa fresca de S. minima.
given that common salvinia is one of several invasive species found in Louisiana waterways, I can't help but feel like I'm in an awesome biological fantasy, (albeit a bit more understated). Ms. Parys has also done research on the impact of red imported fire ants on the weevil mentioned above(PDF link), the abstract for which I had the fortune to translate as well.
ain't science grand?
