Schistosomiasis is one of the most important parasitic diseases in tropical and subtropical areas. Its prevalence is associated with the distribution of freshwater snails, which are their intermediate hosts. Thus, control of freshwater snails is the solution to reduce the transmission of this disease.

- Control of snail hosts is an effective method to interrupt schistosomiasis transmission, and the compound Luo-Wei (tea-seed distilled saponin) shows promise as a molluscicide.
- Laboratory and field tests demonstrated that 4% TDS had significant lethal effects on various snail species, with high mortality rates observed within a week.
- While 4% TDS exhibited moderate toxicity in some non-target organisms like quail and shrimp, it was found to be highly toxic to zebrafish, raising environmental safety concerns.
The mating system of B. alexandrina was studied under laboratory condition by allozyme analysis and SDS-PAGE protein analysis for parent snails and their progenies of two successive generations produced by self and cross fertilization. Allozyme analysis detected 11 genetic loci in 3 enzymes; ACP (3 loci), LDH (2 loci) and EST (6 loci).
