The viability of a formulation of the fungus Monacrosporium thaumasium (Drechsler, 1937) was evaluated for the biological control of bovine gastrointestinal nematode parasites. Two groups of seven female calves each, holstein x zebu crossbred, four to six months of age, were placed in Cynodon dactylon pastures. In group A, each animal received 20g of pellets of M. thaumasium orally twice a week during a four-month period that began with the onset of the rainy season (October, 2001). In group B (control), the calves did not receive any fungal treatment. The counts of eggs per gram of faeces (EPG) for anima1s of the group B were significantly greater (P< 0.05) than those for animaIs of the group A and the difference of the EPG between the animals of group A and B at the end of the study period was 88,8%. The nematodes of the Cooperia genus were the most prevalent in the both pastures. It is concluded that use of this dose and periodicity of application of M. thaumasium pellets were efficient in the control of bovine gastrointestinal nematode parasites.
