TL;DR: The four spirostanol saponin glycosides isolated from the butanol fraction of the methanolic extract of the leaves of Agave heteracantha exhibited strong molluscicidal activites against Biomphalaria alexandrina and Lymnaea cailliaudi, the intermediate hosts of Schistosoma mansoni and Fasciola gigantica in Egypt respectively.
Abstract: Four spirostanol saponin glycosides were isolated from the butanol fraction of the methanolic extract of the leaves of Agave heteracantha (Agavaceae). The structures of these saponins were elucidated by a combination of spectroscopic analysis and hydrolysis followed by identification of both aglycones as tigogenin and gitogenin as well as the sugar moieties. The four saponins exhibited strong molluscicidal activites against Biomphalaria alexandrina (LC90 = 10, 15, 7 and 9 ppm) and Lymnaea cailliaudi (LC90 = 8, 13, 5 and 6 ppm), the intermediate hosts of Schistosoma mansoni and Fasciola gigantica in Egypt respectively.

TL;DR: Comparison of snail histopathological findings and altered cercarial biology observed between the experimental and control groups indicated that the rotifers may have affected the levels of snail's energy reservoirs, which eventually was found to have had an adverse impact on reproduction, growth and survival of the parasite within the snail host, coupled with its performance outside the snail.
Abstract: Objective
To investigate the effect of rotifer internalization into snail tissue on the development of schistosomes.

TL;DR: Slowly released molluscicide was effective at lower concentrations with increasing concentrations of the applied attractant that could reduce its toxicity to the water ecosystem.
