RESUMO
The life cycle of Moniezia expansa was studied experimentally using 10 species of oribatid mites as intermediate hosts. Four of them became infected, namely Scheloribates laevigatus (76.2%), Sch. latipes (70.8%), Liacarus coracinus (20%) and Platynothrus peltifer (1.1%). The last was found for the first time to serve as intermediate host of M. expansa in Czechoslovakia. The development of the cysticercoid of M. expansa in the oribatid mites at 28 degrees C and 85% relative humidity is completed within 27 days. At 18-20 degrees C and the same relative humidity the development lasts even 97 days.

Scheloribates laevigatus (Koch, 1836) and Scheloribates fimbriatus (Thor, 1930), predominant species of oribatids in soil of Bombay region, were experimentally exposed to infection by uniform suspensions of eggs of Moniezia expansa and M. benedeni. The percentages of mites infected and the average number of cysticercoids developing were observed in 12 sets of experiments. The mites were more readily infected with eggs of M. expansa than with those of M. benedeni. S. laevigatus were infected with M. expansa and less with M. benedeni than S. fimbriatus.
