通过比较夜光藻（Noctiluca damagans）食物泡中猎物的分类组成，研究了夜光藻（Noctiluca damagans）对日本九州西海岸硅藻和沟鞭藻的捕食压力。以及周围水体中的微生物。食物泡中总硅藻和中心硅藻的比例高于周围水体，而甲藻和羽状藻的比例则相反。这些结果表明，捕食压力的N。结果表明，硅藻对总硅藻的压力大于对沟鞭藻的压力，中心硅藻的压力大于羽状硅藻。在中心硅藻中，角毛藻和星杆菌在食物泡中占优势，它们各自的比例高于环境水。它们的长刚毛成链菌落似乎很容易被N.这可能是造成该虫高捕食压力的原因。在中心的硅藻上。
Predation pressure of Noctiluca scintillans on diatoms and thecate dinoflagellates was investigated off the western coast of Kyushu, Japan by a comparison between the taxonomic composition of prey in the food vacuoles of N. scintillans and that in the ambient water. The ratios of total diatoms and centric diatoms in the food vacuoles were higher than those in the ambient water, while thecate dinoflagellates and pennate daitoms showed a reverse trend. These results indicate that predation pressure of N. scintillans on total diatoms is higher than on thecate dino- flagellates, and that the pressure on centric diatoms is stronger than that on pennate ones. Among the centric diatoms, Chaetoceros and Bacteriastrum were dominant in the food vacuoles and their respective ratios were higher than in the ambient water. Their chain-forming colonies with long setae appear to be easily trapped by N. scintillans tentacles and this is probably the cause of the high predation pressure of N. scintillans on centric diatoms.
