With the purpose of investigating the biological aspects of Angiostrongylus vasorum (Baillet, 1866) Kamensky, 1905 in Subulina octona Bruguiere, 1789 experimental infections were carried out with the exposure of 90 adult molluscs to 155 L1 of the parasite/mollusc during 24 hours. The intramollus-can larval development was checked out daily through the chemical digestion of four infected molluscs and one molluscs from the control group during 21 days after infection.
