Amoebophrya属中的寄生甲藻感染并杀死大量自由生活的甲藻。该寄生蜂由于其较高的后代生产率和一定程度的寄主特异性，具有调节有害甲藻水华的潜力。东海原甲藻（Prorocentrum donghaiense Lu）是我国沿海沃茨常见的有害藻种，其寄生性与水华动态的关系研究较少。因此，本研究通过形态学观察和高通量测序技术，系统研究了东海松轮盛期间变形虫的发生、流行和动态。在6种甲藻中发现了寄生虫感染，感染率高达5.13%，而在开花种东海甲藻中发现的阿米巴虫感染很少。
The parasitic dinoflagellates in the genus Amoebophrya infect and kill a number of free-living dinoflagellates. The parasitoid has the potential to regulate harmful dinoflagellate blooms due to its high offspring production rates and a certain degree of host specificity. The planktonic dinoflagellate Prorocentrum donghaiense Lu is a commonly observed harmful algal species in coastal waters of China, and limited studies have been conducted to explore the ecological roles of parasitism in association with bloom dynamics. Thus, the in situ occurrence, prevalence, and dynamics of Amoebophrya during the recurrent blooms of P. donghaiense were systemically studied via morphological observations and high-throughput sequencing. The parasitic infections were identified microscopically in six dinoflagellate taxa with prevalence up to 5.13%, while Amoebophrya infection in the bloomforming species P. donghaiense was rare (
