===Biological control===
A tiny [[weevil]], ''[[Cyrtobagous salviniae]]'', found in the native distribution of ''S. molesta'', is being studied as a [[biological pest control|biocontrol]]. ''C. salvinae'' was first used as a biological control in Australia at [[Lake Moondarra]], a recreational lake in Mount Isa, Queensland in 1980. By mid-1981, the weevil had reduced the population to a few small patches. It ate the leaves of the weed, but preferred the buds. Its larvae ate the roots, rhizomes, and the buds. As the plant died, it turned brown and sank to the bottom of the waterway and decomposed. This weevil was used with success in other parts of the world (13 tropical countries) such as the [[Sepik River]] in Papua, Sri Lanka, [[Lake Ossa]] in Cameroon as part of an AMMCO project<ref>{{cite web |last1=Aristide |first1=Takoukam |title=Local Residents around Lake Ossa volunteer to help remove S. molesta by hand prior to weevil project |url=https://www.ammco.org/img/DSC08282.JPG |website=African Marine Mammal Conservation Organization |publisher=AMMCO |access-date=13 June 2020}}</ref> to restore [[African manatee]]; [[Wappa Dam]] in Queensland, and lagoons (e.g. [[Kakadu National Park]]) in the Northern Territory, Australia.<ref name="csiro1"/> In Australia, the moth, ''[[Samea multiplicalis]]'' was also released in the hopes that it would reduce the size of the weed population. While this moth did become established in Australia and spread, it was not effective as a biological control. A third species, the grasshopper ''[[Paulinia acuminata]]'', was considered, but not released in Australia. However, this grasshopper has been deliberately released for control of ''Salvinia molesta'' in parts of Africa, Sri Lanka and India, and accidentally in Puerto Rico.<ref>Perez-Gelabert, D.E. (2002).
