Distribution of cyathostomin infective larvae (L3) in feces, soil and in Tifton 85 (Cynodon spp. cv. Tifton 85) pasture was studied in the different seasons under tropical climate of Baixada Fluminense, Rio de Janeiro state, Brazil. The aim of this study was to evaluate the distribution of L3 in the feces, pasture and soil, verifying the time of higher larvae recovery. The collections began one week after deposit, and then every 15 days. L3 were recovered in higher number in the fall and winter, dry period, when compared to spring and mainly the summer, rainy period. More larvae were recovered at 8:00 o’clock, although no statistic difference was observed among the collection times for each season. The soil did not demonstrate to be a potential L3 reservoir, considering the low larvae recovery. The environmental conditions of the studied area rendered possible the L3 development and survival in fecal mass, as well as the migration for the pasture, making possible the infection of horses.KEY WORDS: Cyathostomin, ecology, environmental conditions, horses, pasture.
