The investigation of successive steps involved in the infection process of the marine diatoms  Coscinodiscus granii  and  Coscuwdiscus wailesii  by the host-specific parasitoid nanoflagellate (PNF) Pirsonia diadenw showed that flagellates reacted chemokJinokinetically with changes of swimming pattern to the presence of a host diatom. Chemosensory stimulation appeared to induce readiness for infection, whereas attachment and penetration of the diatom cell wall was induced by a mechanosensory response to morphological features on the diatom frustules. The mean swimming speed of  P.diadema  flagellates decreased during their infective lifetime of 3 days from an average of 78 μm s −1  to 51 μm s −1  while the frequency of small loops in the swimming pattern increased from 0.8 to 6.3 loops min −1 . At high  Cgranii  densities, an epidemic was delayed. It is suggested that this could be caused by overlapping gradients of extracellular material released by the diatoms which impaired the sensing of spatial gradients by PNF and, therefore, the location of hosts.
