引言控制血吸虫病的一个重要可行措施是消灭螺类宿主。杀螺剂已广泛应用于现场,但在某些疫区化费昂贵,因此需选择其它控制螺类宿主的措施。应用竞争螺已为众多学者所考虑,然而除角突瓶螺、藁杆双脐螺和杜氏大扁螺外,其它几种螺还未进行深入的现场研究。本文综述在加勒比海地区应用粒蜷螺进行生物学控制的现场试验的结果。粒蜷螺在加勒比海地区的分布 Introduction An important practical measure to control schistosomiasis is to eliminate the snail host. Spironolactone has been widely used in the field, but it is expensive in some endemic areas, so other measures should be taken to control the host. The application of competitive snake has been considered by many scholars, however, except for the hornbill, the snail and the snail, the other snails have not conducted in-depth field studies. This review summarizes the results of a field trial of the biological control of Thrips snail in the Caribbean. Distribution of snail in the Caribbean
