介形虫-钉螺生物链与血吸虫病生物防治

实验室实验说明，某些介形虫是肉食的，它们是血吸虫病媒体钉螺的有效杀灭者。介形虫的繁殖是十分快的，在自然界可以迅速增加数量，达到足够的密度。由此推测，介形虫可以应用于血吸虫病的生物防治。这不仅在科学研究上具有重大理论意义，而且在卫生防疫上具有重要实用价值。

OSTRACODA-ONCOMELANIA BIOLOGICAL CHAINS AND BIOLOGICAL CONTROLS ON SCHISTOSOMIASIS

The experimental study indicates that some ostracods are carnivorous,and thus may be considered as an effective predator for the schistosomiasis vector oncomelania.The rates of predation generally increase as a function of the amounts of ostracods.It is inferred from this reason that the ostracods may be used for biological controls on the schistosomiasis vector oncomelania aiming at the prevention of schistosomiasis.The ostracods may be re-produced rapidly,and increase in quantity to enough density in nature.
