The emergence of schistosome cercariae from snails 3. combined effect of light and temperature on the emergence of schistosoma mansoni and schistosoma haematobium cercariae

, : The emergence of schistosome cercariae from snails 3. combined effect of light and temperature on the emergence of schistosoma mansoni and schistosoma haematobium cercariae. Japanese Journal of Parasitology 30(5): 405-416

The emergence of S. mansoni from Biomphalaria glabrata and S. haematobium from Bulinus globosus was photoperiodic when the snails were exposed to 12-h light/dark cycles at a constant water temperature of C. When hosts were subsequently exposed to continuous illumination, cercarial emergence became nonperiodic. Temperature-induced periodicity was manifested when the hosts were maintained at continuous illumination and exposed to 12-h cyclic temperature variations of C. Photoperiod inversion resulted in photoperiodic emergence of S. mansoni if the cyclic temperature difference did not exceed C. and S. haematobium up to a cyclic temperature difference of C. In both cercarial species, rhythmic emergence could be induced by either prevailing light or temperature conditions, and the illumination affected emergence more than the temperature, especially in S. haematobium.
