title: [The effect of temperature and lighting on the biology of Philophthalmus rhionica (Trematoda) miracidia].
abstract: The influence of temperature and illumination on the process of mature eggs production from the uterus of adults of Philophthalmus rhionica and on the hatching of miracidia has been investigated. Illumination in contrast to the temperature does not play a great role. The temperature factor also defines the larvae duration life and the velocity of their swimming and has some influence on the invasiability of miracidia, which is enhanced with heating. The data received does not confirm the position of Semenov (1977) that in the presence of simultaneous influence of light and temperature the influence of the former factor upon the infection of the fresh-water mollusk Melanopsis praemorsa is more significant.
